I am relatively new to this product. I have been having trouble with the examples included in the VS FORTRAN for the MKL (e.g. dgerx.f90 among others). I don't know, but could my problem be that I have an i7 processor/64-bit Win7 but I am trying to use a Visual Fortran + MKL that is limited to 32 bit? The MKL just doesnt seem to work. I checked the paths included in the library and include tabs and they look ok (library: $(IFortInstallDir)mkl\ia32\lib), (include: $(IFortInstallDir)mkl\include). Thanks.
