Hi Siegmar,<br>
<br>
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.<br>
<br>
Sometime, it can happen that you need to add "./" in front of the
program path, could you try it ?<br>
<br>
For example, in spawn_master.c

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

I would be grateful if somebody can fix the problem. Thank you
very
<br>
much for any help in advance. I've attached my programs. Please
let

me know if you need anything else.

Kind regards
