### CONFIGURATION ########################################################

# This file sets variables that direct the libary build for the
# programmer needs. The file is used for the four standard plattforms

# Specify version of GRX
# Currently only used to generate name of shared libraries for linux
GRX_VERSION=2.4.9

# Specify if you have libtiff.a and corresponding .h files.
# Change setting to 'y' if you have it, or to 'n' if not.
HAVE_LIBTIFF=n

# Specify if you have libjpeg.a and corresponding .h files.
HAVE_LIBJPEG=y

# Specify if you have libpng.a and corresponding .h files.
HAVE_LIBPNG=y

# Specify if one of the above libs requires the
# zlib compression library
NEED_ZLIB=y

# Specify if you want to include printing code from addons
INCLUDE_PRINTING_CODE=n

# Specify if you want to include bmp image code from addons
INCLUDE_BMP_CODE=y

# Specify if you want to include GNU_Pascal (gpc) support
INCLUDE_GPC_SUPPORT=n

# Specify if you want shared library support (Linux console and X11)
INCLUDE_SHARED_SUPPORT=n

# Specify if you want to include BGI support
INCLUDE_BGI_SUPPORT=n

# For cross-compiling, specify prefix for tools including the trailing dash
# (e.g.   i386-mingw32-   for using i386-mingw32-gcc instead of just gcc)
#CROSS_PLATFORM=i586-pc-msdosdjgpp-

# Specify if you want to use Unix tools on DOS-like platforms
HAVE_UNIX_TOOLS=y

# Specify in linux if you want to build the library for x86_64
BUILD_X86_64=y

# For SDL driver the executable prefix EP is used to discriminate 
# between linux X11 and mingw32. Set
#EP=x         ... For linux X11.
#EP=          ... For mingw32
