$
gcc 在 .c 文件上工作正常，但在 .cpp 文件上失败，并显示：
$ gcc：尝试执行“cc1plus”时出错： execvp：没有这样的文件或目录
g++ 失败并提示：
$ g++：未找到命令。
我应该怎么做才能编译 C++ 文件？

$
gcc works fine on .c files but fails on .cpp files saying:
$ gcc: error trying to exec 'cc1plus':
execvp: No such file or directory
g++ fails saying:
$ g++: Command not found.
What should I do to be able to compile C++ files?

gcc-c++ 未安装。
yum list命令显示所有软件包，而不仅仅是已安装的软件包。安装的软件包以与号或“@”符号为前缀。未安装（但可以安装）的软件包缺少 & 符号。要查看安装的内容，请尝试命令
rpm -qa。或者在您的示例中rpm -qa | grep gcc奇怪的是，如果您不只是 grep for gcc，您将能够看到两组之间的“已安装的软件包”和“可用的软件包”输出行。
gcc-c++ is not installed.
The
yum listcommand shows all packages, not just the installed packages. The packages that are installed are prefixed with an ampersand or "@" sign. The packages that are not installed (but are available to be installed) lack the ampersand.To see what is installed try the command
rpm -qa. Or in your examplerpm -qa | grep gccOddly enough, if you didn't just grep for gcc, you would have been able to see the "Installed packages" and "Available packages" output lines between the two sets.
您需要安装 gcc-c++ 软件包：
yum install gcc-c++you need to install the gcc-c++ package:
yum install gcc-c++
