Test fc_blas not linking MKL library #45

Closed miroi closed 9 years ago

miroi commented 9 years ago

On my Linux machine with Intel/MKL installed it founds MKL as the first library:

   $ make

but it does not link it:

The same problem without "--int64". Also I provided the PR for minor fix for Ifort (https://github.com/scisoft/autocmake/pull/46).

miroi commented 9 years ago

Ah,

the autocmake/test/fc_blas/src/CMakeFiles.txt in has default linking of GNU blas:

if(BLAS_FOUND)
    add_executable(example example.f90)
    target_link_libraries(example blas)
else()
    message(FATAL_ERROR "BLAS library not found for the test fc_blas!")
endif()

This has to be rewritten for more intelligent linking of the available BLAS library.

bast commented 9 years ago

Aha. Yes. I will correct it.

miroi commented 9 years ago

Fine; the same correction would be needed for the future fc_lapack test as well.
