[mpich-discuss] MPICH2 on AIX

[Eric Sun]

For src/openpa/src/Makefile, if I don't modify, I got:
        ar cru libopa.a opa_primitives.o opa_queue.o
ar: 0707-126 opa_primitives.o is not valid with the current object file
mode.
        Use the -X option to specify the desired object mode.
So, the AR="ar -X64" set in the configure line didn't apply to this
directory.

For the main Makefile, if I don't modify the "INSTALL=confdb/install-sh"
line by giving the full path, it complains confdb/install-sh not found.

Regarding the network problem, I'll try your suggestions. BTW, for a single
SMP machine, gforker and hydra, which one is more suited?

Thanks!
