“initializer_list”文件未找到

Question

上下文：

you@laptop:~$ clang --version
Debian clang version 3.5.0-10 (tags/RELEASE_350/final) (based on LLVM 3.5.0)

每当我尝试make一个需要c++11支持的脚本时，我都会得到以下输出：

致命错误：“initializer_list”文件未找到

我尝试过将-stdlib=libc++和-std=c++11添加到CXXFLAGS中，但没有成功。

如何修复'initializer_list'错误？

我反复检查了做find /usr/include -name initializer_list的操作，结果返回：

/usr/include/c++/4.9/初始化器_list /usr/include/c++/5/初始化器_list

编辑:这是Makefile。

可以运行以下命令查看包含文件的搜索路径：

# clang++ -E -x c++ - -v < /dev/null

对于Docker映像，我使用的输出如下：

编译器抱怨它无法在用于initializer_list搜索的路径列表中找到<...>。我在这个目录中找到了它：

# find /opt/llvm/include/c++/v1 -name initializer_list
/opt/llvm/include/c++/v1/initializer_list

我建议检查您的LLVM安装对于上面所示的默认搜索路径设置是否正确。
