# Minimal LibPNG for EDuke32
|
||
|
|
# based on contrib/pngminim/encoder/pngusr.dfa of libpng
|
||
|
|
#
|
||
|
|
# Usage: from libpng source root and assuming zlib source in ../zlib,
|
||
|
|
# make -f scripts/pnglibconf.mak DFA_XTRA=./minipng.dfa CPP="gcc -E"
|
||
|
|
# make -f scripts/makefile.gcc libpng.a
|
||
|
|
#
|
||
|
|
# To clean up:
|
||
|
|
# make -f scripts/pnglibconf.mak clean
|
||
|
|
# make -f scripts/makefile.gcc clean
|
||
|
|
#
|
||
|
|
# For zlib, the following files are included in the 'mini' archive:
|
||
|
|
# crc32.o deflate.o adler32.o zutil.o trees.o
