[Trilinos-Users] linking against blas/lapack

[Baker, Christopher G.]

Those are symbols from the GNU Fortran compiler libraries (libgfortran.a,
I believe). You will need to add that library to the library list. See if
this works:
-D BLAS_LIBRARY_NAMES:STRING="blas_LINUX;gfortran"
-D LAPACK_LIBRARY_NAMES:STRING="lapack_LINUX;gfortran"
-D BLAS_LIBRARY_DIRS:PATH=/tmp/tramanto/lapack/lapack-3.3.1
-D LAPACK_LIBRARY_DIRS:PATH=/tmp/tramanto/lapack/lapack-3.3.1
