Hi Siegmar,

We cannot reproduce this error on our test machines (Solaris i386, Ubuntu x86_64) by using your programs. And unfortunately we do not have Solaris Sparc machine thus could not verify it.

Sometime, it can happen that you need to add "./" in front of the program path, could you try it ?

For example, in spawn_master.c MPI: A Message-Passing Interface Standard
#define SLAVE_PROG      "./spawn_slave"

Hi,

today I've built mpich-3.2rc1 on my machines (Solaris 10 Sparc,
Solaris 10 x86_64, and openSUSE Linux 12.1 x86_64) with gcc-5.1.0
and Sun C 5.13. I still get the following errors on my Sparc machine
which I'd already reported September 8th. "mpiexec" is aliased to
'mpiexec -genvnone'. It still doesn't matter if I use my cc- or
gcc-version of MPICH.

I would be grateful if somebody can fix the problem. Thank you very
much for any help in advance. I've attached my programs. Please let
me know if you need anything else.


Kind regards
