Link error in Mixed language (CPP calling f77-imsl)

[pchidamb]

Hi My main function is in CPP. I created fortran static lib and linked with CPP exe. Fortran static lib calls imsl lib. Here I have comprehended 4 scenarios. Please give me some input to resolve the link error in case 2. ===================================================================================================== Platform: Vista 32-bit, VS 2008.

DCOPY would be available in MKL.  I've never had access to IMSL for ifort, so don't know if that's the expected way of resolving this dependency.  The buildlog should show whether an attempt was made to link against MKL.

Yes, that is correct. IMSL requires MKL.
