MPL-related Compilation Error in MPI and Graph Parallel libraries

[Denis Arnaud <denis.arnaud_boost@…>]

When compiling Boost, prepared with CMake of the ​1.40.0-cmake2 version, with a GCC 4.4.1 compiler on a 64bit Linux platform, there are two MPL-related errors:

For that error, the line 64 of $BOOST/boost/mpi/detail/mpi_datatype_oarchive.hpp must be changed, so that: BOOST_MPL_ASSERT((sizeof(T)==sizeof(int_type)));

be replaced by: BOOST_MPL_ASSERT_RELATION( sizeof(T), ==, sizeof(int_type) );

And:

For that error, a header file inclusion is missing around the line 22 of $BOOST/boost/graph/distributed/detail/mpi_process_group.ipp: #include <cstdio>

I attach the corresponding patch. To apply it, just go to the $BOOST directory, copy the patch (boost-mpl-compilation-fix.patch file) into there, and type something like: patch -p1 --dry-run < boost-mpl-compilation-fix.patch and, if everything seems fine: patch -p1 < boost-mpl-compilation-fix.patch

This appears to have already been fixed in r57782 (for the cstdio issue) and r56978 (for the BOOST_MPL_ASSERT issue).
