#37495: ubsan doesn't work with clang 3.2 ------------------------------------+-------------------------------- Reporter: arsenm2@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.1.2 Keywords: clang,cmake,ubsan,llvm | Port: clang-3.2 ------------------------------------+-------------------------------- If you try to use ubsan with clang, it always fails: $ /opt/local/bin/clang -fsanitize=undefined arst.c Undefined symbols for architecture x86_64: "___ubsan_handle_add_overflow", referenced from: _main in arst-nGlYc7.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) The fix is clang should build should use cmake instead of autotools since it's basically the preferred LLVM build system at this point. http://llvm.org/bugs/show_bug.cgi?id=14341 -- Ticket URL: <https://trac.macports.org/ticket/37495> MacPorts <http://www.macports.org/> Ports system for Mac OS
