I've got a program that I've been trying to parallelize with Microsoft MPI. The program is functioning well on its own, but I'm running into issues when I try to load a DLL.
When I try to load the DLL using the C "LoadLibrary" function, the function returns a null pointer, and the program stops executing.
Both the application and the DLL are written in C programming language. The application has been compiled using Visual Studio, with options turned on to link the program with MPI libraries as described here. The DLL is compiled using the MingW GCC compiler for Windows. The application and the program are both 64 bit.
Do I need to compile the DLL with MS-MPI libraries as well? Are there any other issues that could be causing this issue? The DLL and program sit in the same directory, and when I use the standard version of the program compiled with GCC, it has no problems loading the DLL.
