我在编译时遇到问题 .c和 .cpp使用 gcc 的文件和 g++ ，对于这两种情况，我都收到了消息:

g++(or gcc): error trying to exec 'cc1plus': execvp: No such file or directory`

我已经尝试重新安装 gcc 和 g++并确保它们的版本相同。

编辑:我使用的是 ubuntu 16.04.1 LTS，g++ 和 gcc 的版本都是 5.4.0 20160609。

以下是 echo | g++ -v -xc++ -fsyntax-only - 的输出:

这就是用 gcc -v 编译一个 hello world 程序的输出:

最佳答案

您的 GCC 中有些东西坏了安装(另请阅读 GCC environment variables 和 spec files )。

^{同时检查您的环境，确保避免使用任何GCC_EXEC_PREFIX 环境变量}

我建议使用 aptitude 重新安装:

aptitude reinstall gcc-5 g++-5

(也许您需要将两次出现的 5 替换为 6，至少在较新版本的 Ubuntu 上是这样)

然后用 gcc -v 编译一些 hello world 程序以确保它能正常工作。
