[Trilinos-Users] Erro Epetra_CrsMatrix

[Michael A Heroux]

Virginia,

The undefined references are to the four Fortran functions that are in
Epetra.  First you should determine whether or not the symbols are in
libepetra.a and, if so, confirm that the name mangling matches what is
expected (i.e., it appears that a double underscore is expected).

One other things to consider:  Do you have two Fortran compilers, one of
which is being used by configure to determine the name mangling and another
which is actually compiling the Fortran kernels?

I hope this helps.

Mike
