[Boost-users] order of headers with Boost.Serialization and Boost.MPI

Hello,

I'm writing a code that uses Boost.MPI to send some GMP
(http://gmplib.org/) datatypes around.
Since I do not want to change GMP, I'm using the "non-intrusive"
serialization support (code in attached
file "gmpxx_boost_serialization.hpp").  However, I'm running into a
strange include-order mess:

* If I include first my "gmpxx_boost_serialization.hpp" and _then_
"boost/mpi.h", then I get a slew of errors (attached file
"errors.txt")

* If I reverse the include order, and include "boost/mpi.h" _first_,
then everything compiles fine.

Is this to be expected, or am I doing something wrong in my code?

For the record, I'm compiling on Ubuntu 10.10, gcc 4.4.5, arch. amd64.

Thanks for any hint!

Best regards,
Riccardo Murri
