[petsc-users] Configuring PETSc with OpenMPI

[Sal Am]

Thanks Satish for quick response,

I tried both of the above, first removing the options --with-cc etc. and
then explicitly specifying the path e.g.
--with-cc=/usr/local/depot/openmpi-3.1.1-gcc-7.3.0/bin/mpicc etc..
Netiher worked, the error is still the same telling me "did not work" I
have attached the log file.

Thanks
