Aspen Plus migration compaq to intel....

[Stefan_Heyne]

Hi,

I am using fortran with IMSL in the process flowsheeting software ASPEN Plus (A+). I built a model with an earlier version of A+ using Compaq Visual Fortran and IMSL and it worked fine. After a reinstall of my computer we moved to Intel Fortran and I am now using Intel Fortran 9.1 with A+ (V7.2).
Now the model does not work any more and I am getting error messages from the compiler inside A+. The link to the IMSL library seems to be ok though (at least I followed the instructions and in the list of linked libraries the IMSL libraries appear as well).
May there be some problem in my code that is causing the problem? It is a bit tweaky in A+ to write fortran and I am quite a beginner actually....
The error message in Aspen states:

*** SEVERE ERROR
ERROR DURING DYNAMIC LINK OF USER ROUTINE(S) OR IN-LINE FORTRAN
PLEASE CHECK FILE _0259eld.ld FOR LINKER MESSAGES.

*** SEVERE ERROR
COULD NOT RESOLVE USER OR IN-LINE FORTRAN SUBROUTINE(S):

SUBROUTINE "ZZFORT" IS MISSING

*** SEVERE ERROR
PROGRAM TERMINATED DUE TO UNRESOLVED ROUTINES

while the linker message file states:

I am aware that this is a rather specific problem to the software A+ but their support could not give any satisfying answers so far (still working on them...) so I am quite desperate to get help.

Thanks for any hints in advance!

Best regards,

It is most likely that you have a mismatch on the calling convention.
I know nothing about Aspen and how/where to set it but maybe this wll help when you talk to their support staff.

As Les Neilson hinted, the default calling conventions of Compaq Fortran and Intel Fortran are different. To nudge Intel Fortran to use the CVF calling convention, use the option /iface:cvf. Note, however, that if you are using a version of the IMSL library built for Intel Fortran, you have to to do a little more work, since you will have to sort out calls to IMSL from your newly compiled code as well as from existing code. Finer control (per-called-routine) over the calling convention is then obtained by using compiler directives in your source code instead of using a compiler option.

Please read the notes that are given under this link at the top of the forum: Migrating from CVF
