The emplace() is new API from C++11. Be aware that GCC suite actually is independent from the libstdc++, so if you have a newer compiler, the compiler might still pick the older libstdc++ without the new API.
This issue doesn't exist at Windows, since Visual Studio is a complete sytem. This issue happens on OSX also, so user must give the compiler a proper MacOS SDK for the new header files etc. On Thu, Apr 5, 2018 at 1:33 PM, suzuki toshiya <mpsuz...@hiroshima-u.ac.jp> wrote: > $ clang++ --version > Ubuntu clang version 3.4-1ubuntu3~precise2 (tags/RELEASE_34/final) (based > on > LLVM 3.4) > Target: x86_64-pc-linux-gnu > Thread model: posix > > But I got following abort: > > cmake-3.11.0/Source/cmLocalGenerator.cxx:553:36: error: no member named > 'emplace' in > 'std::unordered_map<std::basic_string<char>, cmGeneratorTarget *, > std::hash<string>, std::equal_to<std::basic_string<char> >, > std::allocator<std::pair<const std::basic_string<char>, > cmGeneratorTarget > *> > >' > this->GeneratorTargetSearchIndex.emplace(gt->GetName(), gt); > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ > > Grrrr....
