When I try to compile ROMIO (MPI-IO) with pvfs support it fails with a list of “undefined reference” errors. How do I fix this?
The problem here is the pvfs library that needs to be linked in during the compilation. This must be specified when you run the configure script. Here is an example of the command line needed to build the full MPICH distribution with ROMIO and PVFS support: ./configure -opt=-O -device=ch_p4 –with-romio=”-file_system=pvfs” -lib=”-L/usr/lib/libpvfs.
