DOLFIN

slepc 3.3 test failed

Asked by Chaffra Affouda

When building dolfin with slepc 3.3 the test fails with this output. Is the test code valid for 3.3?

-- Checking for package 'SLEPc'
-- SLEPC_DIR is /usr/lib/slepcdir/3.3
-- SLEPc test failed
-- SLEPc could not be found. Be sure to set SLEPC_DIR, PETSC_DIR, and PETSC_ARCH. (missing: SLEPC_LIBRARIES SLEPC_TEST_RUNS)

Performing C++ SOURCE FILE Test SLEPC_TEST_RUNS failed with the following output:

  ierr = SlepcInitialize(&argc, &argv, PETSC_NULL, PETSC_NULL);

This worked fine for me with SLEPc 3.3-p1 built manually from source.

I see SLEPC_DIR is /usr/lib/slepcdir/3.3 in your case. What system are you on and how did you install SLEPc?

I used the dev version of slepc on ubuntu. I think I found the problem. Some of the libraries in slepc might have been moved around in the dev version. I modified FindSLEPc.cmake accordingly. I added ${SLEPC_DIR}/${PETSC_ARCH}/lib to the hints and it worked.

# Get variables from SLEPc configuration
if (SLEPC_DIR)

  find_library(SLEPC_LIBRARY
    NAMES slepc
    HINTS ${SLEPC_DIR}/${PETSC_ARCH}/lib ${SLEPC_DIR}/lib $ENV{SLEPC_DIR}/lib
    DOC "The SLEPc library"
