[petsc-users] Can not find the header file for OpenMPI

[neil liu]

Thanks, I tried the following, and it didn't work.

./configure --download-fblaslapack --with-mpi-lib=/usr/lib64/openmpi/lib
--with-mpi-include=/usr/include/openmpi-x86_64
=============================================================================================
                         Configuring PETSc to compile on your system
=============================================================================================
TESTING: check from
config.libraries(config/BuildSystem/config/libraries.py:186)
*********************************************************************************************
           UNABLE to CONFIGURE with GIVEN OPTIONS (see configure.log for
details):
---------------------------------------------------------------------------------------------
  --with-mpi-lib=['/usr/lib64/openmpi/lib'] and
  --with-mpi-include=['/usr/include/openmpi-x86_64'] did not work
*********************************************************************************************
