linking to a C object in Visual Fortran using Visual Studio

[mhovers]

I have a fortran main program that calls a C routine. I have compiled the C routine using gcc and have a .o file. I cant figure out how to get the Build in Visual Studio to link the fortran and to c *.o files? Where do I tell it the name of the *.o and where it is?

thanks,

This would have to have been built by a gcc targeted for Windows, with no run time library dependency other than on the Windows libraries, such as mingw-gcc. In that case, you should be able to rename as .obj and add to the .obj files of your project. Normally, you would rebuild using the VS compiler for compatibility with ifort.
