Yeah, and I'm wrong too, InterlockedCompareExchange64 is available on
32-bit. I think this is one for Shiqing.
You could build OpenMPI yourself if you have VS2008. It's pretty easy
to do.

I'm using the 32 bit version of OpenMPI. I think the 64 refers to the
size of integer that the function works on, not the operating system
version. I didn't have this problem with VS 2008, so I think they've
changed something in VS 2010. I just don't know how to fix it.

Jeff,
InterlockedCompareExchange64 is a 64-bit-only instruction. Are you
running XP 32-bit (I think you are b/c I don't think there was a XP64
SP3...). You need the 32-bit OpenMPI version. If you are running a
64-bit OS, but building a 32-bit executable, that instruction isn't
available in
Thanks Shiqing,
It turns out that I was able to get the build to work in VS2008, by stepping
back to CMake 2.6 to build it. Not sure why that did the trick but I'm not
complaining...
Another question: Is it possible to run an OpenMPI-based executable on a
single process, without invoking mpi
I'm having a problem using the prebuilt Windows version 1.5.3 with my app
built with MS VisualStudio 2010. I get an error message (for each node)
that says: "The procedure entry point InterlockedCompareExchange64 could
not be located in the dynamic link library KERNEL32.dll". I'm running
