Visual Fotran 6.6 and C .NET

paal · ‎05-26-2003

Hi,

new at this CVF 6.6 and C integration. I'v got a pretty basic C-program (not C++) and I want to use the main routine as a wrapper to my F77 program.

I manage to compile my main.c to main.obj with .NET
I then include the main.obj as part of the resources in my Visual Fortran project, and I compile the .F files OK.
Linking crashes with the following spectacle:

As you can see it seems that the linker gives up at the time when it should be linking to the main.obj file.

My suspicion is that the C-code generated from the .NET thing is not compatible with the obj code required by the visual studio that CVF 6.6 uses. Am I right?

Any workarounds? I'm not able to get my C.NET to work with the .obj files from Fortran either ...

Cheers,

Try the reverse,ie, use the .net linker instead of the VS 6 linker. Also, I believe that debug symbols for c.net differ from those used by VS 6 but I haven't confirmed this and in any event I think that having the latest dbghelp.dll (6.1.0017.2) should make this a non issue, maybe.

HTH,
