# Makefile for windrv demo - Windows 3.x display driver loader for DJGPP/DOS
|
|
#
|
|
# Targets:
|
|
# all - Build libwindrv.a and demo.exe (default)
|
|
# lib - Build only libwindrv.a
|
|
# demo - Build only demo.exe
|
|
# clean - Remove all build artifacts
|
|
#
|
|
# Output:
|
|
# bin/demo.exe - Demo program
|
|
# bin/CWSDPMI.EXE - DPMI host (extracted from tools/cwsdpmi.zip)
|
|
# bin/*.DRV - Driver files (copied from drivers/)
|
|
# win31drv/libwindrv.a - Static library
