Note for users of the Intel compiler (ifc 7.1): After unpacking WHIZARD 1.24, you should apply the patch whizard-1.24-p1 The patch provides a workaround for a compilation problem concerning the entity 'TC' in the Fortran 90 code. (It doesn't hurt to apply this patch if a different compiler is used.) Copy this patch into the whizard directory and type within that directory patch -p1
