Hello, thank you for your help, I am using the devcpp compiler on windows
and I tried changing the libgalcblas.a and libgalcblas.dll links from my
program to mkl_blacs_dll.lib and mkl_blacs_intelmpi.lib and the change did
not work.  I am not a programmer and I am not sure if I have chosen the
right files but there are no .a files in the MKL folder so I am not
certain what to replace them with.
I assumed that you were working on linux (or unix). it seems that mkl is not compatible with devc++ and that you have to use another compiler (intel compiler or the microsoft compiler) or use a different system. I searched on the web and it seems that it is the only possible solution.

go about changing the cblas that GSL uses.

it is simple actually but it depends on the compilation process. If you
use the autotools then you will have to modify gsl.pc (if you use
pkg-config) and replace -lgslcblas with the corresponding parameters for
mkl (please note it is permanent). Now if you have only a makefile, then
just replace -lgslcblas with the appropriate linking options of mkl.
that is pretty much all. I am using this trick for my code.
