#48338: x265 @1.7 fails building using llvm-gcc-4.2 on 10.6.8 -------------------------+---------------------- Reporter: braumann@… | Owner: ays388@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.3 Resolution: | Keywords: Port: x265 | -------------------------+---------------------- Comment (by devans@…): Apple clang 3.0 was introduced in Xcode 4.2. Earlier versions of clang are often found to be problematic and can be blacklisted by version using the compiler_blacklist_versions portgroup {{{ PortGroup compiler_blacklist_versions 1.0 ... compiler.blacklist *llvm-gcc-4.2 {clang < 300} }}} or such depending on what testing with earlier Xcode versions reveals. See XcodeVersionInfo for details of what compilers are available by OS X and Xcode version. Which compilers are selected after black listing is determined by compiler.fallback, the default values of which are set based on Xcode version. See code in [https://trac.macports.org/browser/trunk/base/src/port1.0/portconfigure.tcl base/src/port1.0/portconfigure.tcl] for details. -- Ticket URL: <https://trac.macports.org/ticket/48338#comment:4> MacPorts <https://www.macports.org/> Ports system for OS X
