Right, it's not very well supported everywhere. Clang + Apple's ld is one of those environments where it's not. I test LTCG frequently, but only with GCC and Linux. I know GCC + Binutils (gold and BFD) work properly for static linking, but I'm not sure about Clang + LLVM. Please volunteer to make it work for Clang and macOS. Please see mkspecs/features/ltcg.prf. (because qtbase's build involves creating one static library and using it, you don't need a static build to confirm that it works; just force ltcg in qtbase/ src) -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
