Can't export derived class with a data member of type std::string
| Reported by: | Owned by: | Matthias Troyer | |
|---|---|---|---|
| Milestone: | Boost 1.40.0 | Component: | mpi |
| Version: | Boost 1.39.0 | Severity: | Problem |
| Keywords: | Cc: |
Description
The attached file shows that calling BOOST_CLASS_EXPORT on a derived class that contains a data member of type std::string will fail at compilation.
Adding
namespace boost
{
namespace mpi
{
template<> struct is_mpi_datatype<std::string> : public mpl::true_ {};
}
}
will make it compile and run.

The bug is confirmed and is caused by Boost.Serialization treating std::string and std::wstring as fundamental types to be handled directly by the archive. I'm thinking about how best to solve this for the skeleton&content mechanism, which is the issue here.
