[Trilinos-Users] Epetra configuration problem detecting dggsvd3 in LAPACK

[Widener, Patrick]

Hello - 

In my Trilinos CMake step, Epetra’s check for dggsvd3 in my installed LAPACK (3.6.1) is failing due to a missing symbol from libgfortran. This is causing Epetra to believe I have an older version of LAPACK and consequently a later link error trying to reference dggsvd from Epetra_LAPACK::GGSVD.

The curious thing is that this occurs for me when using mpicc from OpenMPI, but the dggsvd3 check passes and so no link error with mpicc from MPICH.

Has anyone else experienced this? I’m on Mac (El Capitan), gcc 4.9 for both Open MPI and MPICH, Open MPI 1.10 and MPICH 3.3. I pulled from the Trilinos repo last week.

thanks!
