Configure PETSc

0 votes

I'd like to use super_lu solver and I know that I have to configure petsc with superlu. I downloaded the newest version of petsc (3.6.3), installed it into a directory and tried to build dolfin with cmake setting the -DPETSC_DIR to my new directory. Unfortunately cmake says that although it found petscconf.h, "Performing PETSC_TEST_RUNS - Failed".
How can I resolve the issue?

You can check the logfiles in CMakeFiles. Usually, I set PETSC_DIR as an environment variable, not on the CMake command line. Maybe try that?

You should probably also make sure to add $PETSC_DIR/lib to LD_LIBRARY_PATH.

It doesn't help unfortunately. Where would be the appropriate place to install PETSc where cmake probably automatically finds it? Could it be a problem that I am trying to install petsc 3.6.3? Is it required to install petsc with cusp (it says my petsc is not configured with cusp)?

Cmake will find petsc if you set PETSC_DIR environment variable. It doesn't need cusp, but perhaps another error is ocurring. You need to sift through the config log in the CMakeFiles dir.
