[CMake] Fortran MinGW on Windows

[Leek, Jim]

Actually, I'm not sure why it works on Linux either.  That really threw me.

That's for the tip on building shared.  That actually did work.  I would really like a static build, but I guess I'm just going to have to add an if(Windows) if(gfortran) clause or something, huh?

Hi Jim,

I do not quite know why this works fine on Linux, but the issue is caused by the C++ part of the link step. As you are using g++ to link all the C++ runtime libraries, you need to tell it what Fortran runtime libraries to add.
Linking with gfortran automatically ensures all these libraries are taken into account. (If you were to use gfortran as the interface to the linker, then you would need to tell it what C++ runtime libraries are required.)

A way out would be to build these additional libraries as DLLs (shared objects), as then the language-specific linker can be used.

Regards,

Arjen
