Re: [bgl-discuss] xlc/xlf versions of mpicc/mpif77 etc?

[Anthony Chan <chan@xxxxxxxxxxx>]

Just tried to compile a simple mpi programs with ~riley/bin/mpxlc

mpe_work/build_ibm> ~riley/bin/mpxlc test_mpi.c
/opt/ibmcmp/vac/7.0/bin/xlc: 1501-238 configuration file
/etc/opt/ibmcmp/blrts.cfg does not exist
/opt/ibmcmp/vac/7.0/bin/xlc: 1501-270 You may use the vac_configure tool
to create a configuration file.

Is user supposed to use vac_configure to configure the compilers ?
