--- Comment #4 from Václav Šmilauer <eu at doxos dot eu> 2012-03-05 09:20:26 UTC --- I think you understood my source _is_ c++11, but the libs I have to use are not; therefore I have to compile with -std=c++11. The the fix is admittedly trivial and documented, but consists in editing 3rd-party headers. It is ugly and right at the same time. Close this bug if it has no chance.
