Linking problems when mixing with Fortran

[jlperla]

Hi there,

I am using Intel C++ and Fortran 11.0 on Windows. I am doing my builds through nmake (actually cmake generating nmake) and occasionally visualstudio for the C++ builds.

I believe that I have compiled a fortran lib with static linking and the debug version of the runtime. The relevant compiler flags are:

"/debug:full /Od /gen-interfaces /warn:interfaces /libs:dll /threads /c /dbglibs"

linker flags are:

/INCREMENTAL:YES /debug /pdbtype:sept /NODEFAULTLIB

Now I have a C++ project where I am trying to call my function. It is using the MDd runtime dll for sure in C++.

However, when I link I get the error:

1>libifcoremdd.lib(for_main.obj) : error LNK2019: unresolved external symbol _MAIN__ referenced in function _main

Any ideas?

Thanks,

Jesse

As you appear to be using Intel Fortran for Windows, you should find similar questions answered on the corresponding forum. For example, it looks like you may have the situation which calls for -nfor-main in the ifort command line.
