just want to report that I successfully compiled Pixie1.5.5
on SGI/IRIX using gcc3.3. In contrast to my last experiments
with Pixie on that platform some time ago, this time Pixie
was able to produce rendered images that were not all-black!
No extensive tests with complex RIBs done yet, however.
Anyway, since I was also able to compile sdrinfo and related
libraries with SGI-CC (7.4.2), there is now also an aysdr
plugin for Ayam on that platform.
Compilation of the complete renderer with SGI-CC failed.
In order to get Pixie to compile on IRIX, I had to inject a lot
of #include <alloca.h> lines (into every source file that
uses alloca()). I think I reported this long time ago?
Memory usage of gcc went through the ceiling on execute.cpp
so that this file had to be compiled without -O2.

can you tell me if there's a #define to detect IRIX?
All the files that need alloca include common/global.h . Simply placing #include "alloca.h" in there will get your compile working without touching so many files. I'd like to do this only for IRIX though, so if there's a define I can test, that'd be great.
IIRC that would be "sgi" (#ifdef sgi).
