意外删除了 /usr/include/c++ 中的头文件

我意外删除了位于 /usr/include/c++ 中的所有 C++ 头文件的文件夹。我该怎么做才能恢复

更新我确实在 /usr/include/c++ 中恢复了头文件。但是，即使是一个简单的 C++ Hello World 程序也会出现此错误

In file included from /usr/include/c++/4.6/bits/localefwd.h:42:0,
             from /usr/include/c++/4.6/ios:42,
             from /usr/include/c++/4.6/ostream:40,
             from /usr/include/c++/4.6/iostream:40,
             from Hello.cpp:1:

答案1

您可以使用以下命令获取已安装文件到 /usr/include/c++ 的软件包的逗号分隔列表

dpkg --search /usr/include/c++

然后对每个列出的包运行

sudo apt-get install --reinstall

答案2

尝试重新安装 g++

sudo apt-get install --reinstall g++
