#52142: root5 fails to build on Mac OSX 10.11.4 ---------------------------+---------------------- Reporter: donal.hill@… | Owner: jonesc@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: | Keywords: Port: root5 | ---------------------------+---------------------- Comment (by jonesc@…): ( hi Donal !! ) Something is fishy with your log. I don't see the configure step I would expect. Was it really from a clean build ? Please rerun {{{ sudo port clean root5 sudo port install root5 }}} and post the log. Its very strange that MacPorts clang 3.3 is being used, that should not happen, and does not for me. i.e. from my logs I see during the configure phase {{{ Checking for C compiler ... /usr/bin/clang Checking for C++ compiler ... /usr/bin/clang++ Checking for linker (LD) ... /usr/bin/clang++ }}} So it is using the system clang compiler as expected. Can you please, as has already been suggested, make sure you are running the correct and up to date Xcode for OS X 10.11 *and* that you have re- installed the command line tools correctly. See https://www.macports.org/install.php for details. root5 builds fine for me, and also in the build-bots, so it must be something up with your setup.
