Question

更新到macOS 13.3后，编译cpp出现了问题。

5

在升级到Ventura 13.3、安装最新的Xcode和命令行工具后，我在编译任何cpp文件时都会遇到这个错误

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1/cstddef:50:9: error: no member named 'nullptr_t' in the global namespace

这发生在 #include <iostream>

例如：

#include <iostream>

int main() {
    std::cout << "Hello World!";
    return 0;
}

输出结果为：

如果将上面的示例代码放置在Test.C中，以下命令行将导致错误：

clang++ -std=c++17 -stdlib=libc++ -g -c -o Test.o Test.C

- Tema Sysoev

如果我没记错的话，Apple Clang编译器仍然默认使用C++03标准，而nullptr（以及相应的nullptr_t类型）是在C++11中引入的。尝试在构建时添加-std=c++11标志。这有帮助吗？ - Some programmer dude

谢谢建议，但不，它没有。我已经使用了 -std=c++11。 - Tema Sysoev

抱歉，正在编译。 - Tema Sysoev

制作一个小的示例（如果“任何C++文件”都受影响，则使用“Hello World”就足够了），将其添加到问题中，然后显示您尝试编译该小示例时的确切命令行和完整编译器输出。 - Ben Voigt

错误转储缺少编译器调用命令。Xcode总是显示它，但您已决定跳过它。 - 273K

我遇到了这个问题，最终追踪到它是由于我的环境中设置了一个环境变量。

这个变量是

CPLUS_INCLUDE_PATH

我之前遵循了这里描述的解决方法：

https://cmichel.io/fixing-cpp-compilation-bugs-for-the-mac-os-catalina-upgrade/

这涉及到设置一个环境变量（在我的bash .profile文件中）：

CPLUS_INCLUDE_PATH=/usr/local/opt/llvm/include/c++/v1:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include

移除CPLUS_INCLUDE_PATH环境变量解决了问题，编译工作正常！

希望这能帮助其他人克服这个棘手/微妙的构建问题！

如果不行，当我在苹果开发者论坛上发布这个问题时，“eskimo”提供了一些有用的诊断建议。也许那些会有用。帖子的URL是：

https://developer.apple.com/forums/thread/729072

（不幸的是，您可能需要成为注册/登录的苹果开发者才能访问该页面，但是...）他要求我运行的诊断命令如下：

sw_vers
xcode-select -p（显示设置）
xcode-select -s /Library/Developer/CommandLineTools（设置设置）
csrutil status
pkgutil --pkgs
printenv | \grep CPLUS_INCLUDE_PATH（我的自己添加）

如果您继续遇到问题，这些命令的结果可能有助于某人帮助您。

我遇到了同样的问题，这个答案解决了它。在我的情况下，除了执行 rm -rf MacOSX.sdk 之外，我还需要调用 rm -rf MacOSX13.3.sdk。
