Building is very easy. ALL PLATFORMS: Please understand your rights and mine: read the text file LICENSE in the root of the source tree. If you can't abide by it, delete this source tree now. The best documentation for the PhysicsFS API is physfs.h. It is VERY heavily commented, and makes an excellent, in-depth reference to all the functions. UNIX: Edit "Makefile", and follow the instructions. The defaults are probably okay for general purposes, but give it a once over to make sure. If you don't have zLib on your system, you'll need to disable ZIP support. run "make" That's it. The library will be sitting in a new directory called "bin". Run "make install" to install the library for use on your system. WIN32: Download http://icculus.org/physfs/downloads/physfs-win32-support.zip, and unpack in the root of the source directory, preserving directory names. If you did it correctly, there should be a directory named "zlibwin32" in the same directory as "physfs.h". This archive has Visual C project/workspace files and the code needed for zipfile support in PhysicsFS, since most Windows boxes don't have zlib preinstalled. After that, if building with CygWin, follow the Unix instructions, above. If you're using Visual C, point the IDE at physfs.dsw, and build. If you're using any other compiler, send me a patch when you get it working. :) If someone is willing to maintain prebuilt PhysicsFS DLLs, I'd like to hear from you; send an email to icculus@clutteredmind.org. --ryan.
