HELP! A problem about CXML provided Iterative Solver

Hi, I'm greenhand at fortran programming. I have encounter some problems when I try to use CXML provided Iterative Solver to solve linear system. The detail as follows:

When I compile the CXML provided sample progrm "EXAMPLE_ITSOL_5.F"(at X:Program FilesMicrosoft Visual StudioDF98CXMLSAMPLES, X is the VF install driver), the VF6.6 report:"Error: The attributes of this name conflict with those made accessible by a USE statement. [DMATVEC_DRIVER]. The corresponding sentence is:

EXTERNAL DMATVEC_DRIVER, DPCONDL_DRIVER, DPCONDR_DRIVER

The "DMATVEC_DRIVER, DPCONDL_DRIVER, DPCONDR_DRIVER" are CXML library subroutines, and must be defined as External.

How to modify the program?

THANKS!

P.S. I have added the "include 'cxml_include'" sentence

The error message suggests that DMATVEC_DRIVER is declared twice -- once in module CXML, another time as EXTERNAL. Deleting the EXTERNAL line would probably solve it.

Your adding the INCLUDE line is what triggered the problem, as this example was written assuming it wasn't there.

Thank all guys for reply.

Remove the "External" declaration can't settle this problem, because those routine-name was regard as variable of another subroutine and must be declared to EXTERNAL.

If NOT adding the include sentence, these CXML library provided routines such as "DMATVEC_UDIA, DCREATE_ILU_UDIA ..." will be unresolved, however, adding it will bring conflict.

How to altering this program can avoid this paradox?

THANKS

As this example was written, you must explicitly name cxml.lib when you link.

If you wish to use the INCLUDE, you must make the following changes:

Remove DMATVEC_DRIVER from the EXTERNAL declaration.
Change the declaration of DUM to be DUM(1).
