I do not understand...."it's pretty likely that the libpng makefile already knows how to build the archive library (.a extension) as that is a typical build target on systems that are capable of building and using shared libraries." So I paste the Makefile as follow: # makefile for libpng on Linux ELF with gcc# Copyright © 1998, 1999 Greg Roelofs# Copyright © 1996, 1997 Andreas Dilger# For conditions of distribution and use, see copyright notice in png.h # CC=gcc # where "make install" puts libpng.a, libpng.so*, png.h and pngconf.h prefix=/usr/local # Where the zlib library and include files are located# ZLIBLIB=/usr/local/lib# ZLIBINC=/usr/local/include ZLIBLIB=../zlib ZLIBINC=../zlib ALIGN=# for i386:# ALIGN=-malign-loops=2 -malign-functions=2 WARNMORE=-Wwrite-strings -Wpointer-arith -Wshadow -Wmissing-declarations -Wtraditional -Wcast-align -Wstrict-prototypes -Wmissing-prototypes# -Wconversion # for pgcc version 2.95.1, -O3 is buggy; don't use it.
