Dear colleagues

I have written a user element subroutine by FORTRAN but when I call it through the ABAQUS (version 6.4), during loading the inp file, an error produces related to FORTRAN compiler (Compaq visual Fortran 6.5) as below:

ABAQUS JOB 2

ABAQUS version 6.4-PR11

Begin Linking ABAQUS/Standard User Subroutines

9/8/2008 8:41:40 AM

LINK : fatal error LNK1104: cannot open file "ifconsol.lib"

ABAQUS Error: Problem during linking - ABAQUS/Standard User Subroutines

ABAQUS/Analysis exited with errors

or

Abaqus JOB obj

Abaqus Version 6.7-1

Begin Linking Abaqus/Standard User Subroutines

7/30/2008 12:17:06 AM

LINK : warning LNK4044: unrecognized option "FIXED:NO"; ignored

LINK : fatal error LNK1104: cannot open file "LIBIFCOREMD.LIB"

Abaqus Error: Problem during linking - Abaqus/Standard User Subroutines.

 This error may be due to a mismatch in the Abaqus user subroutine arguments. 

 These arguments sometimes change from release to release, so user subroutines

  used with a previous version of Abaqus may need to be adjusted.

Abaqus/Analysis exited with errors

How can I solve this problem and also with different version of ABAQUS (e.g. 6.4 ,6.6 or 6.7), which version of FORTRAN is needed to compatible with ABAQUS?

It is noted that I verify my FORTRAN with ABAQUS through the verification process and ABAQUS completely recognize the FORTRAN compiler.

I appreciate your quick reply.
