Hi all,
I noticed that FindLAPACK and FindBLAS require that you enable Fortran
as language, which causes CMake to check for a working Fortran
compiler.
IMHO, you only need the fortran runtime libraries, cause you're only
linking against the Lapack/Blas libraries. Most Linux distro's have
separate packages for compiler and runtime libraries.
Is there a good reason for FindLAPACK and FindBLAS to require a
working
Fortran compiler?
Best regards,
Marcel Loose.
That's probably because these modules ONLY search for the Fortran
interfaces. Usually one needs a different set of libraries for cblas
and clapack. Also the function names to check for are different (e.g.
cblas_dgemm versus dgemm).
Perhaps someone finds the time to write FindCBLAS.cmake and
FindCLAPACK.cmake... But honestly, if you look at FindBLAS.cmake, that
is quite tough as the various vendor implementations differ strongly
in library names, required compiler flags etc. Linking against Intel
MKL is just a night-mare!
I hope this explains it a bit (although the answer is probably not
very satisfying).
Michael
