Subject: [OMPI users] IRIX: unrecognized opcode `leaf(opal_atomic_mb)'
From: Daniel (lakeat_at_[hidden])

Dear Developers,

I met the same message as Jonathan Day met before,
http://www.open-mpi.org/community/lists/users/2005/09/0138.php

I use
Irix6.5,
Openmpi-1.2.6,
gcc-4.3.0 (gcc g++ gfortran),
gnu-binutils-2.18,
and I saw the answer by Mr. Brain is:
---------------------------------------------------------
Gah - shame on me. I let some IRIX-specific stuff slip through.
Lemme see if I can find an IRIX box and clean that up. The problems
you listed below are not MIPS 32 / MIPS 64 issues, but the use of
some nice IRIX-specific macros. By the way, to clarify, the assembly
has been tested on a MIPS R14K in 64 bit mode (and 32 bit mode using
SGI's n32 ABI -- it will not work with their o32 ABI). Just not on
anything other than IRIX ;).
-------------------------------------------------

but so far I do not understand what does this answer mean, do I need to change some of the codes and add "-n32" option where ld is used?

Please help.
I'd really appreciate your help.

Daniel
