Re: [Boost-users] MPI build problems in Fedora 14 x64

I'm building boost libraries in a Fedora 14 x64. In this Linux distribution, mpi.h is located in /usr/include/openmpi-x86_64 and the build process complains about not finding mpi.h.

This usually indicates that either `bjam` cannot find the MPI compiler (`mpicxx` or `mpic++` both should work on OpenMPI), or that the MPI library is not correctly installed so that `mpicxx` does not look for `mpi.h` in the correct place. To debug, I'd try out the following: 1. Try to compile with `mpicxx -c` a file consisting of the single line `#include ` ; if this fails, your `mpicxx` is not installed properly. 2. Try to append to `project-config.jam` (in the top-level Boost source directory) the line `using mpi : /path/to/mpicxx ;` where `mpicxx` is the one you tried in step 1. -- if this fails, there is possibly some issue with Boost autodetection of the MPI library.
