This program does not use the configure script, but I have been careful to write is as portably as possible -- it should only be using ISO C in conjunction with libpng. UNIX-like systems ================= To build the software on unix, or a compatible build system (eg. cygwin), type the following: make Then copy the png8 executable wherever you want. The documentation in the doc directory can also be copied wherever. If libpng is in a non-standard place, edit the Makefile and set the commented variables accordingly. Other or broken systems ======================= If the Makefile is not usable on your system, you simply need to compile all the .c files and produce a single casm object. E.g. (using the cc command as an example): cc -o png8 *.c
