Hi ! Boost.MPI is currently broken on trunk due to r54934 | ramey | 2009-07-13 23:37:49 +0200 (Mon, 13 Jul 2009) | 2 lines which removed D /trunk/boost/archive/detail/archive_pointer_iserializer.hpp D /trunk/boost/archive/detail/archive_pointer_oserializer.hpp and now MPI fails to compile with: gcc.compile.c++ /build/bjam/boost_1.40.0/libs/mpi/build/gcc-4.4/debug/content_oarchive.o $BOOST_ROOT/libs/mpi/src/content_oarchive.cpp:10:62: error: boost/archive/impl/archive_pointer_oserializer.ipp: No such file or directory It seems that the regression tests don't catch this because no regression tester has MPI configured... It would be nice if at least the Linux testers could install MPI on their machines... I don't know enough about MPI and/or serialization to fix this myself, I just have MPI installed to get less warnings from older Boost.Build versions... Yours, Jürgen -- * Dipl.-Math. Jürgen Hunold !
