Dear MPICH2 developers and users,<br><br>I successfully installed mpich2-1.4.1p1 on an IBM Power5 SMP machine running AIX system. The configure line was<br><span style>./configure --prefix=/install/directory</span><span style> --with-</span><span style>device=ch3:nemesis</span><br>
<br>I had CC=xlc CXX=xlC F77=xlf FC=xlf90<br><br>"configure" and "make" are quite smooth without error. But when I try to compile a testing MPI code (calculating Pi), I receive the following error message:<br>
