[petsc-users] PETSc config error

[amrit poudel]

This is what I have in /lib, and by looking at libmpi.so, I believe I have a shared library.  Would you recommend building a static library for open mpi or is shared library okay?

You need to determine whether your MPI implementation uses static or shared libraries, then pass --known-mpi-shared=1 if it shared and --known-mpi-shared=0 otherwise. You can determine whether it is shared by examining the libraries.

mpicc -showls /home/amrit/MPI/lib                  # look for *.a for shared libs and *.so or *.dylib for shared libs.
