[Trilinos-Users] Trilinos with ATLAS

[Russell Hooper]

Virginia,

It appears that the version of blas you are trying to link against was built
with a different fortran underscore specification (likely double) than what
is expected by Trilinos (single underscore suffix).

You should be able to tell your fortran compiler to not use double
underscores in the suffix of fortran routines, eg. with the gcc compilers,
you can specify this via,

--with-fflags=²-fno-second-underscore²

It may be that this flag or an equivalent for your compiler is set and
should not be, in which case you will need to allow double underscore
suffixes to link against your available blas/lapack libraries.

Hope this helps,

Russell
