Thomas Firstly, I would agree that IRIX is the Unix version that is the easiest to port from Linux (and for that matter Free/Open BSD and others), due to its very broad support of standards (POSIX1, POSIX2, XPG/4, Unix95, SYSV etc.) For example, you take a BSD program, just add -D_BSD_COMPAT to your compilation and you get BSD types, signals, time compatible library and system calls. it is as simple as that. Linux is mostly POSIX so in this sense it is a small subset of the API supported in IRIX. Regarding OpenGL on Linux: there are actually two commercial products supporting it. Check out Xi Graphics (www.xig.com) and metrolink (www.metrolink.com). Their X-servers and OpenGL libraries are not free but certainly available... Hope the helps.
