Subject: Re: [OMPI users] Building OpenMPI v. 1.4.3 in VS2008

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 mpiexec? Say for example that I compiled a simple "Hello world" program such as src/examples/hello_cxx.cc that calls MPI_Init(...). I'd like to start it up (as a serial process) by just calling it from the command line, without reference to mpiexec. Can this be done? If so, could you provide an example syntax? I'm used to doing this with MPICH2, where it works with no problem.

Thanks,

Hi Alan,

I was able to test it again on a machine that has a VS2008 installed. But everything worked just fine for me. I looked into the generated config file(build_dir/opal/include/opal_config.h), and the CMake build system didn't find stdint.h, but it still compiled.

So it was probably some other issues on your platform. It would be very helpful for me to figure out the problem, if you can provide more information, e.g. configure log, compilation error messages and so on.

Regards,
Shiqing

Hi Shiquing,

OK I'll give this a try... however, I realized after some Google searching in the aftermath of my previous attempt to build on VS2008 that the file that I'm missing on that platform is shipped with VS2010.
So I suspect that building on VS2010 will go smoothly as you said. My problem is that my current effort is part of a much larger project that is being built on VS2008. On the one hand I don't want at all to shift that larger code base from VS2008 to VS2010 (and fight the numerous problems that always follow an upheaval of that sort); on the other hand I'm dubious about trying to build my parallel support library on VS2010 and the rest of the code on VS2008.

Is there a way to do what I really want to do, which is build the openmpi source on VS2008?

Hi Alan,

It looks like a problem of using a wrong generator in CMake GUI. I double tested a fresh new downloaded 1.4.3 on my win7 machine with VS2010, everything worked well.

Please check:
1. a proper CMake generator is used.
2. the CMAKE_BUILD_TYPE in CMake GUI and the build type in VS are both Release

If the error still happens, please provide me the file name and line number where triggers the error when compiling it.

Regards,
Shiqing

Hello,

I'm currently trying to build OpenMPI v. 1.4.3 from source, in VS2008. Platform is Win7, SP1 installed ( I realize that this is possibly not an ideal approach as v. 1.5.3 has installers for Windows binaries. However for compatibility with other programs I need to use v. 1.4.3 if at all possible; also as I have many other libraries build under VS2008, I need to use the VS2008 compiler if at all possible).

Following the README.WINDOWS file I found, I used CMake to build a Windows .sln file. I accepted the default CMake settings, with the exception that I only created a Release build of OpenMPI. Upon my first attempt to build the solution, I got an error about a missing file stdint.h. I was able to fix this by including the stdint.h from VS2010. However I now get new errors referencing

__attribute__((__always_inline__))

__asm__ __volatile__("": : :"memory")

These look to me like linux-specific problems -- is it even possible to do what I'm attempting, or are the code bases and compiler fundamentally at odds here? If it is possible can you explain where my error lies?

Thanks for your help,

Alan Nichols
