Created attachment 177081 [details] Proposed patch Using ports libc++ on non-leaf ports is problematic, as the requirement basically flows to all ports that depend on gpgme-{cpp,qt5}. In particular, sysutils/kf5-kwallet was breaking in FreeBSD 9.x because mismatches between libc++ and libstdc++ from gcc48 were causing a gpgme symbol not to be found: backendpersisthandler.cpp:(.text+0xf61): undefined reference to `GpgME::Context::encrypt(std::vector<GpgME::Key, std::allocator<GpgME::Key> > const&, GpgME::Data const&, GpgME::Data&, GpgME::Context::EncryptionFlags)' The attached patch switches the build of both ports to lang/gcc on FreeBSD 9 and the system compiler on FreeBSD 10: * Use USES:compiler-c++11-lib instead of compiler-c++11-lang, as we do need a C++11-compatible standard library. This causes the right compiler to be chosen as described above. * Set _GLIBCXX_USE_C99 so that gpgme-cpp builds with GCC 4.8 (std::to_string() is not exposed by default on FreeBSD). Several other ports need to do the same. * Add a few patches to fix the gpgme-qt5: ** patch-git_b4658f6a1 is a backport from an upstream commit to make the port build with GCC 4.8 without errors. ** patch-lang_qt_src_qgpgmeencryptjob.cpp is a local workaround for the std::bind() bug mentioned in ports r424451. I've verified both ports to build on 9.3 and 10.3.
