Here are some libraries that are used by ASC:
 bzlib  is used for the DOS, WIN32 and Linux version. Although most Linux 
        systems have this library preinstalled, there are two different and 
        incompatible versions around ( 0.9 and 1.0 ). That's why we 
        principially use the one supplied with ASC.
 jpeg   the DOS version requires the Independant Jpeg Library. I had to modify 
        parts of it to be able to load images out of ASCs container files. 
        Since the Linux version does not use it, it is not included here any 
        more. If you want to build the DOS version of ASC, you can get the 
        compiled library (for Watcom C/C++ 11.0) at
           http://www.asc-hq.org/jpeg_ascdos_bin.zip
        and the source code at
           http://www.asc-hq.org/jpeg_ascdos_src.zip
 jpeg-6b The original JPEG library, unmodified. Required by the Win32 
        Version of ASC. Get the JPEG Source code from www.ijg.org and 
        uncompress it into this directory.
 STL    is not included any more. For the DOS-Version, get STLPORT from
        www.stlport.org
 triangul  a polygon triangulation library. Used by DOS and Linux version
 getopt Command line parsing routines for platforms that don't supply getopt
        themselfes (windows for example)
