#50280: arm-none-eabi-gcc @5.1.0_1 does not build on OS X Lion using clang ----------------------+-------------------------------- Reporter: daniel@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Keywords: | Port: arm-none-eabi-gcc ----------------------+-------------------------------- On OS X Lion (10.7.5, Darwin 11.4.2), the default compiler (Clang as `Apple LLVM version 4.2 (clang-425.0.28)`) bails out with an error during build: {{{ :info:build /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports .org_release_tarballs_ports_cross_arm-none-eabi-gcc/arm-none-eabi- gcc/work/gcc-5.1.0/gcc/config/arm/neon.md:3463:10917: fatal error: parser recursion limit reached, program too complex }}} Solution is to blacklist all clang versions in the Portfile by being more inclusive: {{{ compiler.blacklist {clang < 500} }}} This forces the compiler chosen to be `Xcode LLVM-GCC 4.2`, which results in a succesful build, although it complains during staging: {{{ ---> Building arm-none-eabi-gcc ---> Staging arm-none-eabi-gcc into destroot Warning: arm-none-eabi-gcc installs files outside the common directory structure. ---> Installing arm-none-eabi-gcc @5.1.0_1 ---> Cleaning arm-none-eabi-gcc ---> Computing dependencies for arm-none-eabi-gcc ---> Deactivating arm-none-eabi-gcc @4.7.2_0 ---> Cleaning arm-none-eabi-gcc ---> Activating arm-none-eabi-gcc @5.1.0_1 ---> Cleaning arm-none-eabi-gcc }}} -- Ticket URL: <https://trac.macports.org/ticket/50280> MacPorts <https://www.macports.org/> Ports system for OS X
