[Trilinos-Users] Compling on Mac OS X

[Perschbacher, Brent M]

Hello Einar,
  What Mark says is true, blas and lapack are often found correctly without
any intervention, especially on macs where apple makes them easy to find.

The Reason why you are seeing issues though is because you are giving a
compiler option to cmake where we are expecting a library name. The options
to specify tpl library names is something we provide in the case where
someone has an implementation of a library that uses different names than
normal, for instance if they were to put the compiler it was built with in
the file name. For the makefile export generated files those libraries, if
specified are prepended with -l if they are not an absolute path to a file.

Usually you should never have to set those options. If you do need to give
cmake a hint on where to find your libraries because they aren't on a system
path or your path then you can use
-D<tpl_name>_LIBRARY_DIRS=path/to/libaries and
-D<tpl_name>_INCLUDE_DIRS=path/to/includes which will tell cmake to look in
those specific directories first. Generally that should be all  you need to
do.

The best way to fix your problem should be to simply remove the setting of
the libraries for blas and lapack like Mark suggested. The makefile export
system should then be able to properly provide you with the correct blas and
lapack libraries.

Brent
