[Trilinos-Users] [EXTERNAL] Trouble building Trilinos with CLAPACK

[Perschbacher, Brent M]

Chris,
  I have a couple suggestions that may help you. First I highly recommend
using the cmake build of clapack instead of the provided Makefiles. The
biggest reason is that by default the provided Makefiles mangle the blas and
lapack library names differently which makes it difficult to link against
them. The cmake build by default does not do that. Given that the cmake
build for clapack was actually done for the Trilinos project it is generally
more likely to work effortlessly with Trilinos.

We also know of several issues with the llvm compiler that could be causing
you problems. I've actually recently fixed most of the build errors llvm,
however we haven't provided a bug release with those changes yet. There is
one coming, but in the  mean time I would highly recommend using a gcc that
does not use llvm as the back end, we currently test against 4.3, 4.4, 4.5
and 4.6 so any of those should be pretty safe to use.

I hope this helps,

Brent
