<br>
Since MPICH contains absolutely no C++ outside of the now-deleted C++<br>
bindings, that doesn't matter. I can only assume you are using the<br>
MPI C bindings.<br>
<br>
In the rare instance of Linux-related issues, the result of "uname -a"<br>
contains the important info. I've never seen an MPICH bug that was<br>
specific to the Linux distro...<br>
<br>
Just attach your config.log and that will provide the information people need.<br>
