[mpi] non-char strings
The last two checkouts I installed both failed passing strings through boost::mpi communication methods when the element type was not char. So maybe someone besides me will have use for the attached patch which makes it work again. I assume this way of passing strings isn't here to stay anyway since boost::serialization also handles strings. Best regards, Isidor

Could you please file this as a bug report so that it (and the patch) can be kept track of? Thank you. -- Jeremiah Willcock

Did that ([1]). Thanks. Best regards, Isidor [1] https://svn.boost.org/trac/boost/ticket/3394

What do we need to do so that I and not Doug Gregor get informed of new bugs filed? Matthias

Unfortunately Boost.Serialization treats strings as "fundamental types", meaning every archive needs to implement serialization of strings. Your patch needs to replace MPI_CHAR by the appropriate MPI type. I'll apply the correct patch. Matthias
