Hi Alan,
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...
Which version did you use before?
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.
Yes, just run your compiled hello_cxx.exe in the command line prompt,
nothing special.
Regards,
Shiqing
Thanks,
Alan Nichols

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
