Cool. If you're building OpenMPI on 32-bit Windows as well, you won't
have any 64-bit switches to sort out. This part of my instructions:
Visual Studio command prompt: "Start, All Programs, Visual Studio 2008,
Visual Studio Tools, Visual Studio 2008 Win64 x64 Command Prompt" is
slightly wrong for 32-bit Windows, there won't be a Win64 x64 prompt.
There will be only one command prompt option on a 32-bit install (use
that), and CMake will have set you up with a 32-bit build by default, so
you'll be fine. Post back if you need help.

You don't need to check anything alse in the red window, OpenMPI
doesn't know it's in a virtual machine. If you're running Windows
in a virtual cluster, are you running as 32-bit or 64-bit?

Wow thanks a lot guys. I'll try it tomorrow morning. I'll admit
that this time when i saw that there are some header files "not
found" i didn't even bother going through the all process as I
did previously. Could have had it installed by today. Well i'll
give it a try tomorrow and come back to you with a confirmation
of whether it works or not. For the "virtual cluster", should I
select check any of the checkboxes in the red window?
Either way, thanks a lot guys, you've been of great help to me. I
really want to do my project well, as not many almost-18 year
olds get to work with clusters and I'd like to take full
advantage of the experience

Alex,
That red window is what you should see after the first
Configure step in CMake. You need to do the next few steps
in CMake and Visual Studio to get a Windows OpenMPI build
done. That's how CMake works. It's complicated because
CMake has to be able to build on multiple OSes so what you do
on each OS is different. Here's what to do:
As part of your original CMake setup, it will have asked you
where to put the CMake binaries. That's in "Where to build
the binaries" line in the main CMake window, at the top.
Note that these binaries aren't the OpenMPI binaries,
they're the Visual Studio project files that Visual Studio
uses to build the OpenMPI binaries.
See the CMAKE_BUILD_TYPE line? It says Debug. Change Debug
to Release if you want a Release build (you probably do).
Press the Configure button again and let it run. That
should be all clean. Now press the Generate button. That
will build the Visual Studio project files for you. They'll
go to the "Where to build the binaries" directory. From here
you're done with CMake.
Next you have two options. You can build from a command
line, or from within Visual Studio itself. For command-line
instructions, read this:
https://www.open-mpi.org/community/lists/users/2010/02/12013.php
Note that you need to execute the devenv commands in that
post from within a Visual Studio command prompt: Start, All
Programs, Visual Studio 2008, Visual Studio Tools, Visual
Studio 2008 Win64 x64 Command Prompt. I'm assuming you want
a 64-bit build. You need to be in that "Where to build the
binaries" directory as well.
To use Visual Studio directly, start Visual Studio, and open
the OpenMPI.sln project file that's in your "Where to build
the binaries" directory. In the Solution Explorer you'll see
a list of sub-projects. Right-click the top heading:
Solution 'Open MPI' and select Configuration Manager. You
should get a window that says at the top Active Solution
Configuration, with Release below it. If it says Debug, just
change that to Release and it will flip all the sub-projects
over as well. Note on the the list of projects the INSTALL
project will not be checked. Check that now and close the
window. Now right-click Solution 'Open MPI' again and hit
Build Solution. It takes a while to compile everything. If
you get errors about error code -31 and mt.exe at the end of
the build, that's your virus scanner locking the new exe/dll
files and the install project complains. Keep right-clicking
and Build Solution until it goes through. The final Open MPI
include files and binaries are in the
C:\Users\Alex's\Downloads......\installed directory.

PS OpenMPI 1.4.2 doesn't have Fortran support on Windows.
You need the dev 1.5 series for that and a Fortran compiler.

Hey,
I installed a 90 day trial of Visual Studio 2008, and I
am pretty sure I am getting the exact same thing. The log
and the picture are attached just as last time. Any new
ideas?

Alex
