Thank you very much for your reply. I made the change to the c:\program files\boost_1_48_0\tools\build\v2\tools\mpi.jam file, like you mentioned (See attached, I also attached the user-config.jam for your reference). But still have exactly the same error.

C:\Program Files\boost_1_48_0>b2 --toolset=msvc-10.0 --build-type=complete architecture=x86 address-model=32 stage

The system cannot find the path specified.

MPI auto-detection failed: unknown wrapper compiler C:/Program Files/OpenMPI_v1.5.4-win32/bin/mpic++.exe

I have no clue about Windows, but when Boost cannot find my MPI compiler wrapper under Linux, I just append this line to the "project-config.jam" file in the root directory of Boost: using mpi : /path/to/mpicxx ; Of course, you need to replace /path/to/mpicxx above with the path to your "mpic++.exe" executable (or whatever the MPI compiler wrapper is called in Windows).

Hi MM Thank you. Please do have a look this weekend. I want to debug it myself as well, but I am very new to bjam stuff. Please note that I was trying this on 1.48.0 instead of the 1.46.1 in the svn log that you mentioned earlier on. On Tue, Feb 28, 2012 at 4:36 PM, MM wrote:

Hi MM

Thank you very much for your reply. I made the change to the c:\program files\boost_1_48_0\tools\build\v2\tools\mpi.jam file, like you mentioned (See attached, I also attached the user-config.jam for your reference). But still have exactly the same error.

-----------------

Try to add ECHO statements in that function you've changed as well, that gives hints.

It may be an issue with the / and \ in the windows paths.

I'll take a look this weekend,

MM

See if there are more differences with my mpi.jam than what I put in the svn ticket It just worked for me now.
