I am developing an application whose main calculations will be done in a set of Fortran 95 routines. Is it the case that any Fortran routine (integer function, per Gauss documentation) called directly from Gauss MUST NOT be in a Fortran module? I have success in test cases as long as I'm calling functions that are not in a module, but not if the same routines are in a module. If this restriction is true, it makes things a bit more messy on the Fortran end of things.
Thanks for your help!

This particular Aptech poster is not intimately familiar with Fortran 95 modules. However, I think you should be able to find the answer by looking at what it takes to call a Fortran 95 module from C.
I would expect that the worst case is that you would have to make a small C wrapper function to call your Fortran module and then that would be called by DLLCALL. Though I would not expect this to be required.
Some common reasons (which you may well have thought of) that you might be having trouble are:
- The function is not exported in the shared library.
- The compiler has used name decoration to change the name.
If that does not help, let us know your exact error, operating system, and compiler.
