#34200: arb: ld: lto: could not merge in mkptypes.o because Unknown instruction for architecture x86_64 ---------------------------------------+------------------------------------ Reporter: tonybert@… | Owner: matt.cottrell@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.0.4 Keywords: | Port: arb ---------------------------------------+------------------------------------ Comment(by mfeiri@…): Compilation with -O4 activates link time optimizations. It looks like arb can not handle that. A patch was applied upstream to not trigger LTO, see http://bugs.arb- home.de/changeset/8675/trunk/Makefile. Either pull in that patch, or force a non-LTO compiler, or wait for the upstream update. -- Ticket URL: <https://trac.macports.org/ticket/34200#comment:11> MacPorts <http://www.macports.org/> Ports system for Mac OS
