Re: [FLASH-USERS] Re:

Mag,

When I look at the last line of output in your build process, I don't see a
-L/<path-to-mpich>/lib -lmpich -lfmpich , and all the unknown symbols are
from the mpi library, even though you have mpich installed, it doesn't look
like you are linking to it:

 buildstamp.o flash_release.o buildstats.o flashModules.o -L/usr/local/lib
-lhdf5 -lz
flash.o(.text+0x1d): In function `main':
: undefined reference to `mpi_wtime_'

You should also have a -L/<path-to-mpich> -lmpich -lfmpich after the hdf5
and zlib libraries above. At any rate the undefined symbol errors are
definitely because the linker is not finding the mpich library, and fromt he
output you sent me it looks like its not there. Let me know if it is but was
just missing from the output you sent to the list.

Thanks
