[pkg-boost-devel] Fwd: Bug#625093: feel++: FTBFS: stl_uninitialized.h:576:6: error: no matching function for call to 'boost::mpi::allocator<char>::construct(char*)'

[Christophe Prud'homme]

Hi Steve

here is the simplest program I found

----- t.cpp
#include <boost/mpi.hpp>
------ end of t.cpp

in fact the issue arises with the use of the -std=c++0x flag to use
the new c++ standard

compile without -std=c++0x
g++ -I/usr/include/mpi  -c t.cpp
no errors

try compiling with -std=c++0x
 g++ -I/usr/include/mpi -std=c++0x -c t.cpp
