LNK 2019 error

I am linking a static libraryIVF ver 11 project into a C++ solution in Visual Studio 2005, sp1. Getting the link error
libifcoremt.lib(for_init.obj) : error LNK2019: unresolved external symbol __argv references in function _for_rtl_init
libifcoremt.lib(for_init.obj) : error LNK2019: unresolved external symbol __argc referenced in function _for_rtl_init

The C++ project calling this library uses Multithreaded Debug DLL (MDd). This same Fortran project was linked successfully with another C++ project so I don't believe there's a problem with the project settings for the library. In the project which linked successfully, the Intel Fortran libraries used were
libifcoremdd.dll
libifportmd.dll
libmmdd.dll

My question is, what triggered the use of libifcoremt.dll instead of libifcoremdd.dll?
Why would a static library be looking for argc and argv?

There is a problem with the settings for the Fortran project. It needs to match that of the C++ project. Your Fortran project specifies "Multithreaded" (/MT) and the C++ project is using "Multithreaded Debug DLL" (/MDd). The reason for the undefined references is because C/C++ libraries use different names for certain global symbols in static and DLL libraries.

Change the Fortran library project to use the DLL libraries. This may affect your use with other C++ projects that have different libraries specified.

Hi

I may also have the same problem. I get a bunch of LNK 2019 and LNK 2001 errors.

Do you think it might be because of this mismatched setting? (/MT vs. /MDd)?

I unfortunately do not have the source code for the libraries. Just the libraries themselves.

This is with Visual Studio Pro 2008.

Thank you,
Kevin

If you have a library which was built with a non-Intel Fortran compiler, it won't link against Intel Fortran run-time. It looks like it was built with a calling convention resembling stdcall. Many of the same functions come pre-compiled in the MKL library which comes with ifort Professional.
