Hi,

Thanks for your answer.

I have the same problem than the person on the trac with his code and If I add "--compileflags=-DMPICH_SKIP_MPICXX" or "--linkflags=-DMPICH_SKIP_MPICXX " to the boost compile command line I have exactly the same error.

Cheers.

Julien.

It looks like mpicxx.h is having problems.  Try to download http://www.usqcd.org/fnal/example/cpi.c, rename it to a .cpp file, and try to compile it with mpic++.  If you get similar errors, it is a bug in MPICH and you should report it there (you might be hitting
http://trac.mpich.org/projects/mpich/ticket/1582 which mentions the same line number as in your error messages).  If that ends up being the problem, adding -DMPICH_SKIP_MPICXX to your compile flags might act as a workaround.  If you do hit the existing bug, you might want to post a comment on that bug saying that it breaks compiling Boost.MPI with MPICH 3.0.2.
