title: How to build boost::mpi library with Open MPI on Windows with Visual Studio 2010
body: <p>I installed Open MPI 1.5.4 (64 bit) and I am trying to rebuild boost libraries (1.48) with bjam.</p>
  
  <p>I changed user-config.jam file, by adding using mpi line with explicit compiler path (although mpic++ is already in PATH environment variable):</p>
  
  <pre><code>using mpi : "C:/Program Files (x86)/OpenMPI_v1.5.4-x64/bin/mpic++.exe" ;
  </code></pre>
  
  <p>Then I tried to run from command prompt the following command: </p>
  
  <pre><code>bjam toolset=msvc --build-type=complete --with-mpi --address-model=64 stage
  </code></pre>
  
  <p>Unfortunately, the build process still needs more hints. Part of the error reporting looks like:</p>
  
  <pre><code>MPI auto-detection failed: unknown wrapper compiler C:/Program Files (x86)/OpenMPI_v1.5.4-x64/bin/mpic++.exe
  </code></pre>
  
  <p>Did anybody managed to compile Boost MPI with Open MPI under Windows? Am I missing something?</p>
