Because using "-lmkl" returns an error like "-lmkl not found", so, to
remove "-lmkl" from the configure I need to edit the line. That is
what earlier posts in this list (which the FAQ points to) recommends.
I would object to the form of that solution too.
I understand that editinf ./configre by hand isn't the best way of doing this.
What I mean is that the ./configure file, as shipped, contains an
obsolete argument, namely "-lmkl", which causes compilation faliures
because there is no libmkl.* file in ${MKL}/lib/em64t.
So, I get this error:
ld: cannot find -lmkl
In fact, Intel's documentation never mention -lmkl, but
-lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core, for example.
Should I file a bug?
It's an unfortunate fact of life that linking to MKL is awkward, because
of the multiplicity of configurations and versions that exist. The
GROMACS git version has some more intelligence in this department. I'd
only file a bug if you get the same problem with it (see webpage for
instructurions for getting the git version and building it). Also, the
GROMACS developers won't care all that much, because FFTW runs on
everything and is almost indistinguishable in terms of performance, so
putting significant effort into making MKL work nicely isn't very valuable.
