If you have some old library that needs libstdc++, then you're stuck with it for now. That means you must tell your linker not to use libc++, so you need to ensure that the -stdlib=libstdc++ is passed to all steps of the build (compiler and linker). Otherwise you'll get the linker errors you mentioned. > But __GNUC_LIBSTD__ is not defined, hence Q_COMPILER_RVALUE_REFS is > #defined.

Please be aware of the warning about Qt 5.7: support is getting dropped because Qt 5.7 will require <atomic>. Qt 5.6 will be a long-term release, but you may still want to figure out a replacement library or at least a rebuild of it. -- 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
