#45307: clang-3.4 not picking up C++11 headers on 10.6.8 -------------------------+-------------------------------- Reporter: rjvbertin@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: Keywords: | Port: clang-3.4 -------------------------+-------------------------------- Is this a known issue? When building the QtCurve 1.8.18 port, `clang++-mp-3.4 -std=c++11` will pick up a version of #include <utility> that apparently does not define std::forward ... There *is* a utility header in llvm-3.4's install tree (in a "v1" subdirectory), but it's not being found. In other words, macports-clang-3.4 cannot be used to build C++11 projects on OS X 10.6.8, not even with -std=c++0x. Apple's version, basically the same compiler, works fine for those projects on 10.9 . -- Ticket URL: <https://trac.macports.org/ticket/45307> MacPorts <http://www.macports.org/> Ports system for OS X
