Question

我有一个使用SFML的CMake项目，该项目运行良好，但是更新到Xcode 10后，找不到CMake寻找的所有编译器文件。

clang: warning: libstdc++ is deprecated; move to libc++

我不确定如何移动到其他lib源。

我尝试使用set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=libc++")使用该标志。

它也告诉我：Check for working CXX compiler: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++ -- broken。我可以在终端中正常运行g++/c++命令。我认为他们正在同一地点被寻找。

我要编译的CMake文件。其SFML之一： SFML CMake

完整错误消息：

Answer 1

好的。原来我只需要将set(CMAKE_CXX_FLAGS "-stdlib=libc++")添加到我的CMakeLists.txt

Xcode 10更新后CMake找不到stdc ++ 11
