gcc 5 C++ string issue

[Orion Poplawski]

Getting:

/builddir/build/BUILD/mrpt-1.0.2/libs/base/include/mrpt/utils/mrpt_macros.h:296:150:
error: no match for 'operator<<' (operand types are 'std::basic_ostream<char>'
and 'std::ostringstream {aka std::__cxx11::basic_ostringstream<char>}')
  #define ASSERT_NOT_EQUAL_( __A, __B)  { if (__A==__B) { std::ostringstream
s;s<<"ASSERT_NOT_EQUAL_("<<#__A<<","<<#__B<<") failed with\n"<<#__A<<"=" <<__A
<<"\n"<<#__B<<"="<<__B; THROW_EXCEPTION(s.str()) } }


Any idea what wrong here?
