Jim,
I'm having dificulties installing nhc-1.08 under IRIX 6.5 using gcc-3.0.1 to bootstrap the compiler.
I think this might be the first problem - gcc-3 has reputedly made some significant changes over gcc-2, and I'm not sure of the effect such changes might have underneath nhc98.
The first problem I encountered was an incompatability between the prototype of the "system" call on my machine and the one used by nhc.
I would have thought this was pretty harmless - on my Linux box, the standard prototype is extern int system __P ((__const char *__command)); which has never given a conflict with the nhc98-generated prototype extern HsInt system(char*); for me. It could be that gcc-3 is being more strict.
I then resumed compiling and managed to buid the "nhc98comp" executable with no problems. But the first time the build process tried to use this executable it aborted with the following message:
What, run() returned!
Ok, that definitely looks like a bad executable, but I suspect the cause is unrelated to the system() call. Do you have any possibility of using gcc-2.9x instead of gcc-3? If so, I would suggest a second test build would at least cut down the search space, by telling us whether the problem lies with the choice of C compiler or our assumptions about IRIX-6.5. To use a different C compiler from the first one on your PATH, you can use the CC variable at configure-time, e.g. CC=/usr/lib/gcc-2.95.6/bin/gcc ./configure It might also be helpful if you can keep the tree you built with gcc-3 separately. Should gcc-2 work ok, then it could be useful to do some small comparisions between the trees. Regards, Malcolm
