Serializing a UUID into a boost::archive::binary_[io]archive works fine.
However, when changing to a text archive, I get a compiler error with
gcc 4.7 in C++11 mode on Darwin. Here is a small example:
#include
#include
#include
#include
#include
int main()
{
std::vector<char> v;
boost::iostreams::filtering_ostream
stream(boost::iostreams::back_inserter(v));
boost::archive::text_oarchive oa(stream);
boost::uuids::uuid id = boost::uuids::random_generator()();
oa << id;
return 0;
}
The error is in basic_text_oprimitive line 92:
cannot bind 'std::basic_ostream<char>' lvalue to
'std::basic_ostream<char>&&'
Any ideas what's going on? (I attached the full error message below.)
