GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
|
||||
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
License is intended to guarantee your freedom to share and change free
|
||||
software--to make sure the software is free for all its users. This
|
||||
General Public License applies to most of the Free Software
|
||||
Foundation's software and to any other program whose authors commit to
|
||||
using it. (Some other Free Software Foundation software is covered by
|
||||
the GNU Library General Public License instead.) You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
this service if you wish), that you receive source code or can get it
|
||||
if you want it, that you can change the software or use pieces of it
|
||||
in new free programs; and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
anyone to deny you these rights or to ask you to surrender the rights.
|
||||
These restrictions translate to certain responsibilities for you if you
|
||||
distribute copies of the software, or if you modify it.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must give the recipients all the rights that
|
||||
you have. You must make sure that they, too, receive or can get the
|
||||
source code. And you must show them these terms so they know their
|
||||
rights.
|
||||
|
||||
We protect your rights with two steps: (1) copyright the software, and
|
||||
(2) offer you this license which gives you legal permission to copy,
|
||||
distribute and/or modify the software.
|
||||
|
||||
Also, for each author's protection and ours, we want to make certain
|
||||
that everyone understands that there is no warranty for this free
|
||||
software. If the software is modified by someone else and passed on, we
|
||||
want its recipients to know that what they have is not the original, so
|
||||
that any problems introduced by others will not reflect on the original
|
||||
authors' reputations.
|
||||
|
||||
Finally, any free program is threatened constantly by software
|
||||
patents. We wish to avoid the danger that redistributors of a free
|
||||
program will individually obtain patent licenses, in effect making the
|
||||
program proprietary. To prevent this, we have made it clear that any
|
||||
patent must be licensed for everyone's free use or not licensed at all.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License applies to any program or other work which contains
|
||||
a notice placed by the copyright holder saying it may be distributed
|
||||
under the terms of this General Public License. The "Program", below,
|
||||
refers to any such program or work, and a "work based on the Program"
|
||||
means either the Program or any derivative work under copyright law:
|
||||
that is to say, a work containing the Program or a portion of it,
|
||||
either verbatim or with modifications and/or translated into another
|
||||
language. (Hereinafter, translation is included without limitation in
|
||||
the term "modification".) Each licensee is addressed as "you".
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running the Program is not restricted, and the output from the Program
|
||||
is covered only if its contents constitute a work based on the
|
||||
Program (independent of having been made by running the Program).
|
||||
Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's
|
||||
source code as you receive it, in any medium, provided that you
|
||||
conspicuously and appropriately publish on each copy an appropriate
|
||||
copyright notice and disclaimer of warranty; keep intact all the
|
||||
notices that refer to this License and to the absence of any warranty;
|
||||
and give any other recipients of the Program a copy of this License
|
||||
along with the Program.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and
|
||||
you may at your option offer warranty protection in exchange for a fee.
|
||||
|
||||
2. You may modify your copy or copies of the Program or any portion
|
||||
of it, thus forming a work based on the Program, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in
|
||||
whole or in part contains or is derived from the Program or any
|
||||
part thereof, to be licensed as a whole at no charge to all third
|
||||
parties under the terms of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively
|
||||
when run, you must cause it, when started running for such
|
||||
interactive use in the most ordinary way, to print or display an
|
||||
announcement including an appropriate copyright notice and a
|
||||
notice that there is no warranty (or else, saying that you provide
|
||||
a warranty) and that users may redistribute the program under
|
||||
these conditions, and telling the user how to view a copy of this
|
||||
License. (Exception: if the Program itself is interactive but
|
||||
does not normally print such an announcement, your work based on
|
||||
the Program is not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Program,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Program, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program
|
||||
with the Program (or with a work based on the Program) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable
|
||||
source code, which must be distributed under the terms of Sections
|
||||
1 and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three
|
||||
years, to give any third party, for a charge no more than your
|
||||
cost of physically performing source distribution, a complete
|
||||
machine-readable copy of the corresponding source code, to be
|
||||
distributed under the terms of Sections 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer
|
||||
to distribute corresponding source code. (This alternative is
|
||||
allowed only for noncommercial distribution and only if you
|
||||
received the program in object code or executable form with such
|
||||
an offer, in accord with Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form of the work for
|
||||
making modifications to it. For an executable work, complete source
|
||||
code means all the source code for all modules it contains, plus any
|
||||
associated interface definition files, plus the scripts used to
|
||||
control compilation and installation of the executable. However, as a
|
||||
special exception, the source code distributed need not include
|
||||
anything that is normally distributed (in either source or binary
|
||||
form) with the major components (compiler, kernel, and so on) of the
|
||||
operating system on which the executable runs, unless that component
|
||||
itself accompanies the executable.
|
||||
|
||||
If distribution of executable or object code is made by offering
|
||||
access to copy from a designated place, then offering equivalent
|
||||
access to copy the source code from the same place counts as
|
||||
distribution of the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program
|
||||
except as expressly provided under this License. Any attempt
|
||||
otherwise to copy, modify, sublicense or distribute the Program is
|
||||
void, and will automatically terminate your rights under this License.
|
||||
However, parties who have received copies, or rights, from you under
|
||||
this License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||
|
||||
5. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Program or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Program (or any work based on the
|
||||
Program), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the
|
||||
Program), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute or modify the Program subject to
|
||||
these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties to
|
||||
this License.
|
||||
|
||||
7. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Program at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Program by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Program.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under
|
||||
any particular circumstance, the balance of the section is intended to
|
||||
apply and the section as a whole is intended to apply in other
|
||||
circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system, which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
8. If the distribution and/or use of the Program is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Program under this License
|
||||
may add an explicit geographical distribution limitation excluding
|
||||
those countries, so that distribution is permitted only in or among
|
||||
countries not thus excluded. In such case, this License incorporates
|
||||
the limitation as if written in the body of this License.
|
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions
|
||||
of the General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Program
|
||||
specifies a version number of this License which applies to it and "any
|
||||
later version", you have the option of following the terms and conditions
|
||||
either of that version or of any later version published by the Free
|
||||
Software Foundation. If the Program does not specify a version number of
|
||||
this License, you may choose any version ever published by the Free Software
|
||||
Foundation.
|
||||
|
||||
10. If you wish to incorporate parts of the Program into other free
|
||||
programs whose distribution conditions are different, write to the author
|
||||
to ask for permission. For software which is copyrighted by the Free
|
||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||
make exceptions for this. Our decision will be guided by the two goals
|
||||
of preserving the free status of all derivatives of our free software and
|
||||
of promoting the sharing and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||
REPAIR OR CORRECTION.
|
||||
|
||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
||||
POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the program's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||
This program is free software; you can redistribute it and/or modify
|
||||
it under the terms of the GNU General Public License as published by
|
||||
the Free Software Foundation; either version 2 of the License, or
|
||||
(at your option) any later version.
|
||||
|
||||
This program is distributed in the hope that it will be useful,
|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
||||
GNU General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU General Public License
|
||||
along with this program; if not, write to the Free Software
|
||||
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
||||
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program is interactive, make it output a short notice like this
|
||||
when it starts in an interactive mode:
|
||||
|
||||
Gnomovision version 69, Copyright (C) year name of author
|
||||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||
This is free software, and you are welcome to redistribute it
|
||||
under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, the commands you use may
|
||||
be called something other than `show w' and `show c'; they could even be
|
||||
mouse-clicks or menu items--whatever suits your program.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
||||
necessary. Here is a sample; alter the names:
|
||||
|
||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
||||
`Gnomovision' (which makes passes at compilers) written by James Hacker.

|
||||
|
||||
This General Public License does not permit incorporating your program into
|
||||
proprietary programs. If your program is a subroutine library, you may
|
||||
consider it more useful to permit linking proprietary applications with the
|
||||
library. If this is what you want to do, use the GNU Library General
|
||||
Public License instead of this License.

At the time of this writing, DAPHNE will compile fully under these unix'ish
|
||||
platforms:
|
||||
- Ubuntu Linux version 11.04 (x86)
|
||||
- i386 GNU/Linux (primary platform)
|
||||
- i386 FreeBSD
|
||||
- Sparc Solaris (untested)
|
||||
|
||||
MAC OSX USERS SHOULD USE THE XCODE PROJ INSIDE THE MACOSX DIRECTORY!!!
|
||||
The MAC OSX Makefile method is obsolete and is no longer maintained!
|
||||
|
||||
--------------------------
|
||||
STEP BY STEP INSTRUCTIONS:
|
||||
--------------------------
|
||||
|
||||
- Make sure you have g++, make, and sed installed.
|
||||
|
||||
- Install these libraries (with headers) if you don't already have them:
|
||||
SDL 1.2 (tested with 1.2.14, older versions may work fine)
|
||||
SDL NOTE:
|
||||
To have minimum hardware acceleration, SDL needs to be built with "xv" support.
|
||||
"OpenGL" support is also recommended for better hardware acceleration.
|
||||
SLD_image
|
||||
SDL_ttf
|
||||
libfreetype6-dev
|
||||
Ogg Vorbis (libogg, libvorbis, libvorbisfile)
|
||||
Zlib
|
||||
GLEW (http://glew.sourceforge.net)
|
||||
|
||||
- You will most likely have to convert the source files line endings to Unix format.
|
||||
Install dos2unix or similar tool for this.
|
||||
|
||||
- Now you are ready to compile. Daphne doesn't use the traditional
|
||||
autoconf/automake nonsense. Instead, it uses a separate Makefile for
|
||||
each platform. To compile under GNU/Linux, open up a termianl window and
|
||||
type this (from the src directory):
|
||||
|
||||
cp Makefile.vars.linux_x86 Makefile.vars
|
||||
make
|
||||
|
||||
(You'd do something similar if you were compiling under the other platforms.)
|
||||
|
||||
- You also need to compile libvldp2.so which comes with DAPHNE and has its
|
||||
own set of instructions inside the vldp2 directory. When you get there
|
||||
type:
|
||||
|
||||
chmod +x configure
|
||||
./configure
|
||||
make -f Makefile.linux
|
||||
|
||||
- If compiling SINGE then you also need to comple libsinge.so separately
|
||||
before making Daphne. Go to the game/singe folder and type:
|
||||
|
||||
make -f Makefile.linux
|
||||
|
||||
- Once you got your libraries compiled then return to the main "src"
|
||||
directory. Begin the compiling process by typing "make".
|
||||
|
||||
-----------------------------------------------------------------------------
|
||||
|
||||
An alternate way...
|
||||
|
||||
Go to the "src" folder and rename the appropriate Makefile.vars.linux_x??
|
||||
to Makefile.vars. Open up a terminal window and type the following:
|
||||
|
||||
chmod +x buildme.sh
|
||||
./buildme.sh
|
||||
|
||||
|
||||
If everything goes correctly it should compile daphne with the vldp2
|
||||
and singe libraries.
|
||||
|
||||
|
||||
---------------------- LINUX QUESTIONS -------------------------
|
||||
|
||||
+ "Can't load VLDP2 library"
|
||||
|
||||
Open up a terminal window. Navigate to daphne's main directory and type:
|
||||
|
||||
export LD_LIBRARY_PATH=.:$LD_LIBRARY_PATH
|
||||
|
||||
Another way is to copy libvldp2.so and linsinge.so to /usr/lib.
|
||||
|
||||
sudo cp libvldp2.so /usr/lib
|
||||
sudo cp libsinge.so /usr/lib
|
||||
|
||||
+ Daphne hangs after quitting.
|
||||
|
||||
This is a known issue with static singe builds under linux.
|
||||
Use a dynamic build instead.

The following document explains how to compile Daphne under Windows.

*******************************************************************************
|
||||
|
||||
1. Check part E for what libraries you need to get. If you need
|
||||
to generate your own libraries then go ahead and do so.
|
||||
2. On the very same folder where you found this text file double click
|
||||
on the solution file "daphne_vs2003.sln".
|
||||
3. Select the type of build you wish to create (debug or release).
|
||||
4. Take a minute to add the necessary paths to your project's directory
|
||||
lists for "include" and "library" settings.
|
||||
5. Check daphne's C++ pre-processor settings and if needed modify
|
||||
it to meet your needs (eg, add/remove ZLIB_WINAPI or BUILD_SINGE).
|
||||
6. Check daphne's Linker Input Settings so all libraries
|
||||
are correctly spelled.
|
||||
7. Build your solution.

B. Tested Development Environments
|
||||
*******************************************************************************
|
||||
|
||||
|
||||
Daphne has been tested to compile under the following Microsoft products:
|
||||
|
||||
Visual C++ 6
|
||||
Visual C++ .NET 2003 (a.k.a. Visual C++ 7.1)
|
||||
Visual C++ 2005 (a.k.a. Visual C++ 8.0)
|
||||
Visual C++ 2008 (a.k.a. Visual C++ 9.0)
|
||||
Visual C++ 2010 (a.k.a. Visual C++ 10.0)
|
||||
|
||||
|
||||
*******************************************************************************
|
||||
C. Compiler Quirks:
|
||||
*******************************************************************************
|
||||
|
||||
If you are using Visual C++ 6:
|
||||
|
||||
- Make sure you have MASM installed. VS7.1 automatically comes with this
|
||||
installed. If you are using VS6, you may need to upgrade to
|
||||
service pack 5 and then install the Processor Pack in order to get MASM.
|
||||
There are other ways to get it installed, but this way requires the
|
||||
shortest explanation :).
|
||||
|
||||
- Get SDL-devel-1.x.xx-VC6.zip.
|
||||
|
||||
|
||||
If you are using Visual C++ 2003:
|
||||
|
||||
- If compiling your own libogg and libvorbis libraries then get
|
||||
version 1.2.0 for both. That's the last version that supported this
|
||||
compiler. You can find it by browsing older release versions
|
||||
at the xiph.org address below:
|
||||
|
||||
http://downloads.xiph.org/releases/ogg/
|
||||
|
||||
|
||||
If you are using Visual C++ 2005:
|
||||
|
||||
- Make sure you apply Service Pack 1. Some newer libraries (eg, libSDL)
|
||||
may generate errors if you don't.
|
||||
|
||||
|
||||
If you are using Visual Studio 2010 Express Edition:
|
||||
|
||||
- Be aware this edition may not compile libogg nor libvorbis
|
||||
right out of the box. Visual Studio 2008 Express Edition does
|
||||
not have this problem.
|
||||
|
||||
|
||||
The following may apply to any Visual Studio version:
|
||||
|
||||
- It is very likely you will have to update your project's linker
|
||||
properties so that it correctly spells the right filenames for the
|
||||
libraries you want to compile against. For example depending on what you
|
||||
use you may have to rename vorbis.lib to libvorbis.lib or
|
||||
zlib.lib to zlibwapi.lib. This is usually done at the property pages for
|
||||
your Daphne project:
|
||||
|
||||
+ For VS2003: At the Solution Explorer right click on "daphne"
|
||||
and select "Properties". From there choose "Linker"-->"Input"
|
||||
|
||||
+ For VS2005/2008/2010:
|
||||
|
||||
(Alt+F7)-->Configuration Properties-->Linker-->Input
|
||||
Check the field "Additional Dependencies".
|
||||
|
||||
- Visual Studio VC++ 2005 and newer need an additional package called
|
||||
"VC Redistributable Package" (eg, vcredist_x86.exe) installed for
|
||||
any compiled program to work outside the developing environment.
|
||||
|
||||
Some computers have this installed by other programs or Windows updates.
|
||||
This will solve error messages like "the application configuration is
|
||||
incorrect". Keep this in mind when installing your custom created
|
||||
Daphne on a target machine.

|

D. Library Quirks (applies to all compilers):
|
||||
*******************************************************************************
|
||||
|
||||
|
||||
|
||||
+++++++++ SDL Libraries +++++++++
|
||||
|
||||
- When dealing with SDL libraries make sure
|
||||
to choose the correct one for the version of Visual C you
|
||||
are using. Usually there is a separate zip file with the suffix
|
||||
"VC6", "VC8" or "VC".
|
||||
|
||||
+++++++++ OGG and VORBIS +++++++++
|
||||
|
||||
- When working with libogg and libvorbis you will have to
|
||||
compile the libraries on your own. Take a look inside
|
||||
the directory structure libogg and libvorbis. Be sure to select
|
||||
the right folder pointing the project or solution file
|
||||
corresponding to the compiler version you are using.
|
||||
These folders are usually named "vs2003", "vs2005" or "vs2008".
|
||||
Failure to match these with the correct compiler may result
|
||||
in compiler errors.
|
||||
|
||||
- libvorbis uses libogg, so compile libogg first and later add the
|
||||
library path to your compiler "VC++ directories" configuration
|
||||
for libvorbis.
|
||||
|
||||
- libvorbis has four main projects, but the ones you need
|
||||
are libvorbis and libvorbisfile.
|
||||
|
||||
|
||||
+++++++++ ZLIB +++++++++
|
||||
|
||||
- Save some time by downloading pre-compiled zlib libraries.
|
||||
You can find them at http://www.winimage.com/zLibDll/index.html
|
||||
Be aware you will still need to get the header files as well.
|
||||
- Latest ZLIB versions require the word "ZLIB_WINAPI"
|
||||
declared in the project's pre-processor project settings.
|
||||
- Library naming conventions changed too.
|
||||
Use "zlibwapi.lib" instead of "zlib.lib"
|
||||
|
||||
|
||||
|
||||
*******************************************************************************
|
||||
E. Libraries to Get:
|
||||
*******************************************************************************
|
||||
|
||||
|
||||
To compile Daphne you need to have the following libraries:
|
||||
|
||||
+ libSDL - http://www.libsdl.org
|
||||
+ libGLEW - http://glew.sourceforge.net
|
||||
+ libOgg - http://xiph.org/downloads/
|
||||
+ libVorbis - http://xiph.org/downloads/
|
||||
+ zlib - http://www.zlib.net/
|
||||
|
||||
|
||||
+++++++++ Optional: Compiling SINGE with Daphne +++++++++
|
||||
|
||||
To compile the SINGE add-on for Daphne you also need to add:
|
||||
|
||||
+ libSDL_image - http://www.libsdl.org/projects/SDL_image/
|
||||
+ libSDL_ttf - http://www.libsdl.org/projects/SDL_ttf/
|
||||
|
||||
|
||||
SINGE add-on is built by default. If you wish to disable it then
|
||||
remove the words "BUILD_SINGE" on daphne's pre-processor project settings.
|
||||
|
||||
|
||||
|
||||
|
||||
*******************************************************************************
|
||||
F. Organizing your libraries:
|
||||
*******************************************************************************
|
||||
|
||||
|
||||
It's recommended you create a folder where to extract
|
||||
all the downloaded librares. You will need to add new directories to the
|
||||
Include category to point to the include files for the packages you
|
||||
just downloaded. For example, you might add an entries like these:
|
||||
|
||||
c:\mylibs\sdl-1.2\include
|
||||
c:\mylibs\libogg-1.2.0\include
|
||||
c:\mylibs\zlib-1.14
|
||||
c:\mylibs\glew\include
|
||||
|
||||
|
||||
To access the Directories tab of your compiler:
|
||||
|
||||
+ VS6, go to Tools->Options then click on
|
||||
Projects->Directories tab.
|
||||
+ VS7.1 go to Tools->Options->Projects then click on the
|
||||
Directories tab.
|
||||
+ VS2005/2008 go to:
|
||||
Tools->Options->Projects and Solutions->VC++ Directories.
|
||||
|
||||
|
||||
You will also need to add entries to the "Library" category (as opposed
|
||||
to the "Include" category you just added entries for).
|
||||
Your library entries might look like this:
|
||||
|
||||
c:\mylibs\sdl-1.2\lib
|
||||
c:\mylibs\sdl_mixer-1.2.0\lib
|
||||
C:\mylibs\libogg-1.2.0\win32\VS2005\Win32\Release
|
||||
c:\mylibs\zlib-1.14\dll32
|
||||
c:\mylibs\glew\lib
|
||||
|
||||
|
||||
|
||||
- How to set Global VC++ Directories in Visual Studio 2010:
|
||||
|
||||
VS2010 does things a little bit differently. Use the following
|
||||
instructions to set a group of directories globally to all
|
||||
projects inside a solution:
|
||||
|
||||
1. Select Tools->Settings->Expert Settings.
|
||||
2. Open up the daphne_vs2010.sln solution file.
|
||||
3. Select View->Property Manager and expand the node for 'daphne'.
|
||||
4. Expand the node for either "Debug" or "Release".
|
||||
5. Right click on "Microsoft.Corp.<Platform>.user"
|
||||
and select "Properties".
|
||||
6. At the "Daphne Property Pages" window, select
|
||||
Configuration Properties->VC++ Directories
|
||||
|
||||
7. Add the additional directories for include and library.
|
||||
Hit OK when you are done.
|
||||
8. Save your project and exit Visual Studio altogether.
|
||||
9. Relaunch Visual studio and open your daphne solution.
|
||||
Your directories changes should now apply globally
|
||||
to all the projects in the solution.
|
||||
|
||||
|
||||
|
||||
|
||||
*******************************************************************************
|
||||
G. Opening and Compiling the Daphne project:
|
||||
*******************************************************************************
|
||||
|
||||
|
||||
+ Go to File->Open Solution and open the daphne_vs2003.sln (or double click
|
||||
on the solution in the src folder).
|
||||
|
||||
+ If using a newer Visual C++ compiler versions then you will see the
|
||||
Conversion Wizard pop up. Let it convert your project to your Visual C++
|
||||
version. Take a moment to read "Troubleshooting Compiler/Linker Errors" and
|
||||
fix the problem with ".\daphne.rc(10) fatal error RC1015".
|
||||
|
||||
+ Select the kind of build you want (Debug or Release).
|
||||
|
||||
+ Make sure your C++ pre-processor settings have all the right values!
|
||||
Make sure your Linker "Input" settings have all the libraries
|
||||
correctly spelled!
|
||||
|
||||
+ On the menu toolbar select "Build->Build Solution".
|
||||
|
||||
|
||||
At this point you should be ready to compile. Good Luck!
|
||||
|
||||
|
||||
|
||||
*******************************************************************************
|
||||
H. Troubleshooting Compiler and Linking Errors:
|
||||
*******************************************************************************
|
||||
|
||||
|
||||
+ .\daphne.rc(10) : fatal error RC1015: cannot open include file 'afxres.h'
|
||||
|
||||
Happens when converting the VS2003 project solution to a newer
|
||||
Visual Studio version. Open up daphne.rc and change the
|
||||
following line:
|
||||
|
||||
#include "afxres.h"
|
||||
|
||||
|
||||
to this:
|
||||
|
||||
#include "windows.h"
|
||||
|
||||
+ LINK : fatal error LNK????: cannot open input file '*******.lib'
|
||||
|
||||
Visual Studio can't find the specified library.
|
||||
Probably the file is misspelled in the linker properties.
|
||||
Usually happens with zlib, libogg or libvorbis libraries.
|
||||
|
||||
Check that the library files declared in the project linker
|
||||
"INPUT" properties are correctly spelled and that your library
|
||||
directories are pointing to the right places.
|
||||
|
||||
+ error PRJ0019: A tool returned an error code from
|
||||
"Performing Custom Build Step"
|
||||
|
||||
Happens when compiling SINGE. Fix it by moving your "src" folder
|
||||
to a path that does not use spaces in its name.
|
||||
|
||||
+ error LNK2001: unresolved external symbol __imp___CrtDbgReportW
|
||||
|
||||
Happens when trying to generate a multi-threaded release build
|
||||
on a debug build.
|
||||
|
||||
Fix it by going to daphne's Property Pages (right click
|
||||
on the project name in the Solution Explorer pane then choose
|
||||
"Properties"). Once you are there select
|
||||
|
||||
Configuration Properties->C/C++->Code Generation
|
||||
|
||||
Change the value in the "Runtime Library" option
|
||||
to "Multi-threaded Debug DLL".
|
||||
|
||||
+ error LNK2005: <some function> already defined in LIBCMTD.lib
|
||||
|
||||
You'll get this error when using VS2005 without
|
||||
the Service Pack 1 installed against the libraries in the SDL package
|
||||
"SDL-devel-1.?.??-VC8.zip". Fix it by updating your compiler
|
||||
to SP1 or by using "SDL-devel-1.?.??-VC6.zip" instead.
|
||||
|
||||
+ vorbisfile.h(59): error C3861: '_fseeki64': identifier not found, even with
|
||||
argument-dependent lookup
|
||||
|
||||
Happens when tryping to compile a newer libvorbis library
|
||||
with the older Visual Studio 2003. Quick fix is to
|
||||
use an older libvorbis version (or a newer VS compiler).
|
||||
|
||||
Long fix: Open up vorbisfile.h and go to line 59. Change the
|
||||
following:
|
||||
|
||||
return _fseeki64(f,off,whence);
|
||||
|
||||
to this:
|
||||
|
||||
return fseek(f,off,whence);
|
||||
|
||||
|
||||
+ LINK: ... unresolved external symbol _crc32 ....
|
||||
|
||||
Happens when trying to compile with the latest
|
||||
zlib versions. Add the word "ZLIB_WINAPI" (without the quotes)
|
||||
to the preprocessor compile settings for the "daphne" project.
|
||||
|
||||
|
||||
|
||||
+ "This application has failed to start because <SOME.DLL> was not found.
|
||||
Re-installing the application may fix this problem"
|
||||
|
||||
Project "daphne_test" expects to find SDL.dll and inpout32.dll
|
||||
after it's done compiling. When it doesn't it complains with this
|
||||
message, but the project will finish successfully. You can happily
|
||||
hit OK and ignore this message.
|
||||
|
||||
...Or you can copy SDL.dll and inpout32.dll to the place
|
||||
where Visual Studio dumps all the generated programs (one directory
|
||||
above the "src" folder).
|
||||
|
||||
|
||||
*******************************************************************************
|
||||
I. Installing your generated daphne file
|
||||
*******************************************************************************
|
||||
|
||||
You got through all the hurdles and got daphne to compile. Congrats.
|
||||
Now what next? At this point you might be tempted to simply copy
|
||||
the generated daphne.exe to the folder where your official daphne release
|
||||
is located.
|
||||
|
||||
While this may work, the official daphne distribution may have
|
||||
DLL files that are incompatible with your custom created daphne.
|
||||
If you get DLL related errors then you need to copy the appropriate
|
||||
DLL files as well. Those binary files can be found at each of the
|
||||
library directories you setup previously. In order to save you some time
|
||||
here is a list of what you need to look for. Copy these files in the same
|
||||
location where you place your generated daphne.exe file:
|
||||
|
||||
|
||||
+ vldp2.dll and singe.dll from the same folder you
|
||||
got daphne.exe.
|
||||
|
||||
+ SDL.dll from the SDL-1.x.xx folder
|
||||
|
||||
+ glew32.dll from the libglew folder
|
||||
|
||||
+ zlib.dll (if using version 1.14) or
|
||||
zlibwapi.dll (if using a newer zlib version like 1.2.5)
|
||||
|
||||
+ SDL_image.dll, zlib1.dll, libpng12-0.dll from
|
||||
the SDL_image folder.
|
||||
|
||||
+ SDL_ttf.dll and libfreetype-6.dll from the SDL_ttf folder.
|
||||
|
||||
+ libogg.dll from somewhere inside the libogg folder.
|
||||
|
||||
+ libvorbis.dll and libvorbisfile.dll from within the libvorbis folder.
|
||||
|
||||
+ inpout32.dll is found in the official daphne build.
|
||||
If you don't see it then run Daphne Loader and
|
||||
update to the latest version.
|
||||
|
||||
+ msvcp71.dll and msvcr71.dll if using VS2003.
|
||||
|
||||
+ For VS2005 and newer you need to install the Visual C++
|
||||
Redistibutable package (vcredist_x86.exe) on the target machine.
|
||||
Simply copying the DLLs over won't work.

|

# 1 - Build all required libraries (SDL, SDL_mixer, Ogg, Vorbis) from source.
|
||||
# When configuring, use "./configure --prefix $HOME/slibs --disable-shared"
|
||||
# When "make install"ing, it will install everything into your $HOME directory
|
||||
# inside the slibs directory. That way, you don't need to be root.
|
||||
# 2 - Add $HOME/slibs/bin to your PATH, by doing:
|
||||
# "export PATH=$PATH:$HOME/slibs/bin"
|
||||
# (This allows the sdl-config script to run properly.)
|
||||
# 3 - Copy this file to Makefile.vars, type make, and you should be good to go.
|
||||
|
||||
# where your library include files are installed

// DAPHNE : Dragon's Lair / Space Ace Emulator
|
||||
// Started by Matt Ownby, many people have contributed since then
|
||||
// Begun August 3rd, 1999
|
||||
|
||||
// ORIGINAL GOAL (we've obviously done much more than this now hehe):
|
||||
|
||||
// To emulate the original Dragon's Lair / Space Ace game such that the original ROM's are executed
|
||||
// properly, the joystick and buttons are emulated, and the Laserdisc Player is properly
|
||||
// controlled
|
||||
// In short, so that the original game may be played with the following requirements:
|
||||
// - Original Dragon's Lair Laserdisc
|
||||
// - Original Dragon's Lair ROM's (disk files, not the physical ROM's heh)
|
||||
// - A laserdisc player
|
||||
// - A common modern computer (i386 Win32, i386 Linux most likely)
|
||||
// No other original hardware (motherboard, power supply, harness) required!

Instructions can have the following fields:

`A' : 8 bits

`B' : 9 bits

`C' : 9 bits

`Bx' : 18 bits (`B' and `C' together)

`sBx' : signed Bx

value is the unsigned value minus K. K is exactly the maximum value

for that argument (so that -max is represented by 0, and +max is

represented by 2*max), which is half the maximum for the corresponding

(*) In OP_CALL, if (B == 0) then B = top. C is the number of returns - 1,

next open instruction (OP_CALL, OP_RETURN, OP_SETLIST) may use `top'.
|
||||
|
||||
(*) In OP_VARARG, if (B == 0) then use actual number of varargs and
|
||||
set top (like in OP_CALL with C == 0).
|
||||
|
||||
(*) In OP_RETURN, if (B == 0) then return up to `top'
|
||||
|
||||
(*) In OP_SETLIST, if (B == 0) then B = `top';
|
||||
if (C == 0) then next `instruction' is real C
|

|
||||
(*) For comparisons, A specifies what condition the test should accept

** Implementation of tables (aka arrays, objects, or hash tables).

** Tables keep its elements in two parts: an array part and a hash part.

** Non-negative integer keys are all candidates to be kept in the array
|

** part. The actual size of the array is the largest `n' such that at

** Hash uses a mix of chained scatter table with Brent's variation.
|

** A main invariant of these tables is that, if an element is not
|

** in its main position (i.e. the `original' position that its hash gives

** to it), then the colliding element is in its own main position.
|

** Hence even when the load factor reaches 100%, performance remains good.
