Problem building on SGI/Irix 6.5

[Kevin Cowtan]

Hi!

I'm trying to build gcc 3.0.1 (or 3.0) on IRIX 6.5, and having a few problems.
 I am using the gcc bootstrap mode to build gcc, g77 and g++.
 gcc and g77 build fine, and I think the g++ compiler builds OK,
but libstdc++ fails on me (I think - I'm not a Makefile guru).

The failure is in stage 3 - the error seems to be finding gthr.h.
I can confirm that the directory it is looking in does not exist.
/y/people/cowtan/work/gcc-3.0.1/mips-sgi-irix6.5/libstdc++-v3/../
contains:
config.cache  libiberty/  libstdc++-v3/  mabi=64/

Thanks for any advice. Yes, I have tried the copy of gcc-3.0
on the SGI freeware site, without success.

Kevin
