[more linker errors snipped out]

Those are linker errors. You need to tell gcc to link with the GSL.
Pass the -lgsl and -lgslcblas parameters at the end to gcc:

    gcc matrix_test.cpp -lgsl -lgslcblas

This, of course, is assuming you correctly compiled the GSL and put it
somewhere where gcc can find it. See section 2.2.1 of the GSL manual:
