I realize this is an old post (which is why I quoted so much of it),
but I recently received a request from an MKL developer to supply a
response as follows:


Instead of using -lmk_vml_p4 and -lmkl_p4 he should be using
-lmkl and -lvml. The names are in these two files which will then
dispatch the appropriate .so based on cpuid check the names in the
processor specific .so's are decorated and that is why they will not
help him directly.

Linking information can be found in our Getting Started Guide:
http://www3.intel.com/cd/software/products/asmo-na/eng/307884.htm. I
looked it up and the information is there, but though we've changed
this a thousand times, it always seems this could be arranged better.
