I'm trying to debug some Fortran code, and I've followed the instructions at http://www.mathworks.com/help/techdoc/matlab_external/f32489.html#f18756 and have tried it with the yprime.c as suggested (after switching back to the C compiler, of course).

The Visual Studio hangs when I run the program. I'm using 2008 instead of 2005 but wouldn't expect this to be an issue. I'm operating 64-bit Matlab. My Visual Studio looks to be an x86 (32-bit) program, but I don't enough to know whether that is the source of the problem. I get the same problem with either the Fortran 11.1 compiler or the Microsoft Visual C++ 2010 Express compiler. Has anyone experienced a similar issue?

This seems like it could be a Visual Studio issue. Are you able to debug other C/C++ libraries/executables without any problems on the same installation of Visual Studio? (Also, when you compile yprime.c, make sure that you select the same version of Visual Studio using "mex -setup")

Also, FYI - since your original question was about debugging FORTRAN code, note that Visual Studio can only be used to debug C/C++ code. You could follow a similar process with a FORTRAN debugger however (I'm not a FORTRAN programmer, so have no advice on what debugger to use).

This information:

http://www.mathworks.com/help/techdoc/matlab_external/f28378.html

says that Microsoft Visual Studio tools can also be used to debug Fortran code. Is this bad information?

Is there a way to run the Fortran mex code (with the gateway function) directly from Visual Studio and still have access to Matlab functions? This page http://www.codeproject.com/KB/cpp/MatlabVS.aspx seems to indicate there is a way to do this for C code, but I'm not familiar enough with what preprocessor directives and .h files would need to be present to be able to do this in Fortran.
