Ok -- yes -- I got a clean build by removing the<font face="monospace" class=""> --with-mpi</font> flag.<br class="">
<br class="">
What about this <font face="monospace" class="">--enable-large-single-req</font> flag, though?<br class="">
Does it require that I build OpenMPI specially, or use a specific kind of switch or FileSystem?<br class="">
I only use 64-but systems these days...<br class="">
<br class="">
Thanks,<br class="">
