#51642: GCC does not honor -march=native -------------------------+-------------------------------- Reporter: noloader@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: | Keywords: Port: | -------------------------+-------------------------------- Comment (by ryandesign@…): Setting `CXX=/opt/local//bin/x86_64-apple-darwin12-gcc-4.9.3` is unusual. Usually, you would set `CXX=/opt/local/bin/g++-mp-4.9`. Have you tried that already? Does it change anything? Any particular reason you're using gcc 4.9.3? The latest stable version is 6.1.0, available in the gcc6 port. -- Ticket URL: <https://trac.macports.org/ticket/51642#comment:2> MacPorts <https://www.macports.org/> Ports system for OS X
