# Makefile for zlib under OS/2 using GCC (PGCC)
# For conditions of distribution and use, see copyright notice in zlib.h

# To compile and test, type:
#   cp Makefile.os2 ..
#   cd ..
#   make -f Makefile.os2 test

# This makefile will build a static library z.lib, a shared library
# z.dll and a import library zdll.lib. You can use either z.lib or
# zdll.lib by specifying either -lz or -lzdll on gcc's command line

CC=gcc -Zomf -s

CFLAGS=-O6 -Wall
#CFLAGS=-O -DMAX_WBITS=14 -DMAX_MEM_LEVEL=7
#CFLAGS=-g -DDEBUG
#CFLAGS=-O3 -Wall -Wwrite-strings -Wpointer-arith -Wconversion \
#           -Wstrict-prototypes -Wmissing-prototypes

#################### BUG WARNING: #####################
## infcodes.c hits a bug in pgcc-1.0, so you have to use either
## -O# where # <= 4 or one of (-fno-ommit-frame-pointer or -fno-force-mem)
## This bug is reportedly fixed in pgcc >1.0, but this was not tested
CFLAGS+=-fno-force-mem
