Hi,

Do you have OpenMP directive in C/C++ source code at all? If that is the case, this could be a problem. Since your C/C++ is compiled with Visual C++ and it has its own Openmp implemenation. While your Fortran code is compiled with PGI and it also has its own implementation.

Let say, you don't have OpenMP code in C/C++, you will need to make sure that your main program/project is linked with PGI OpenMP library instead of Visual C++ OpenMP library.

Thanks Hongyon;

No, I don't use any OpenMP in the C++ code; all the computationally-intensive stuff is kept within the Fortran DLL.

That being the case, is there a library I should explicitly link with, over and above those already listed in my linker command line (see my previous post)?

In your Visual C++ main project, this is for a Release configuration:

Open up property page and set following properties:

1)
Configuration Properties -> C/C++ -> Code Generation -> Runtime Library -> Multi-threaded(/MT)

2) Configuration Properties -> General -> Common Language Runtime support ->No Common Language Runtime support

3) Configuration Properties -> Linker -> General -> Additional Library Directories

Added following 2 lines,
the first line depends on which version your PVF is.
the second line depends on where you put your Fortran library.

C:\Program Files\PGI\win64\10.9\lib
C:\Users\myname\Documents\Visual Studio 2008\Projects\openmpf\openmpf\x64\Release

4) Configuration Properties -> Linker -> Input -> Additional Dependencies -> [...]
Added following lines. openmpf.lib is your Fortran library name.

openmpf.lib
-defaultlib:pgmp
-defaultlib:pg
-defaultlib:pgf90
-defaultlib:pgf90_rpm1
-defaultlib:pgf902
-defaultlib:pgf90rtl
-defaultlib:pgftnrtl
-nodefaultlib:msvcrt
-nodefaultlib:msvcmrt
-defaultlib:libcmt
-defaultlib:pgc
-defaultlib:libnspgc
-defaultlib:oldnames



Also, I would make it static library instead of dll library. I am not sure it create DLL properly in PVF. If it works for you, go ahead.

I also noticed that you use MKL library. I don't have experience using them but it may have some specific library that you might use with PGI.

I posted above that you should build static library instead of DLL.
All the dynamic library build in PVF is now should be as good as static library.
