<html><P><BR>> Attached are five files. RPM files are from the Fedora 10 mpich2 rpm <BR>> install. source files are from the Fedora 10 mpich2 source install as <BR>> described in the installer's guide. The fedora9 file is from the Fedora <BR>> 9 mpich2 source install (the version at that time, not the one currently <BR>> posted).<BR>> <BR>> Tried mpicxx with a program that does not use MPI and that program runs <BR>> fine. If I take the MPI cpi executable from the Fedora 9 installation, <BR>> that executable runs fine under Fedora 10. That file was built using <BR>> mpicxx. If I build that same source using mpicxx under Fedora 10, the <BR>> program builds fine but will not execute. It fails upon trying to run <BR>> MPI_Init with an illegal instruction error.<BR>> <BR>> Something I want to try is the Fedora 9 mpicxx resulting command line <BR>> (from -show) in Fedora 10 since that line is different from the one <BR>> Fedora 10 is using.<BR><BR>Is it possible that you might have overwritten some of the FC9 files <BR>with an FC10 MPICH2 install? The error you are getting seems like the <BR>library files belong to FC9; that's why when you run a program compiled <BR>in FC9 works, but one that's compiled in FC10 doesn't.<BR><BR>An easy way to try this is to install from source into a different <BR>directory (not /opt) and try it out from there.<BR><BR> -- Pavan<BR></P>
<P>The machine running Fedora 10 is a fresh install, as is MPICH2-1.1. There is nothing from the old Fedora 9 machine. Someone said that Fedora 10 has MPICH2 binaries. Could that be causing a problem if I do a fresh MPICH2 install?</P></html>
