matth301 is on a distinguished road
I am running Fluent 15.0 on Windows 7 64 bit. I am trying to compile a UDF that references some Fortran subroutines. I have compiled the subroutines into a static library file, libmc.a. However, when I run nmake to compile the full UDF library, I get the following error:

Quote:

NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 11.0

When I have encountered similar errors on Linux, the solution was reference the Fortran compiler in the Makefile:

Code:
    $(LD) $(LDFLAGS) $(OBJECTS) $(USER_OBJECTS) -L/soft/gcc/4.7.2/lib64 -lgfortran -o $@
Does anyone know how to fix this error in Windows? I don't see a linking line in the Fluent UDF makefile for Windows. Thanks for any suggestions!
