CentOS gcc编译报错：gcc: error trying to exec ‘cc1plus‘: execvp: No such file or directory（原因：g++没安装）

Posted 2022-05-25 Dontla

如下报错：

[root@localhost ky_volume]# gcc book250.cpp -o book250
gcc: error trying to exec 'cc1plus': execvp: No such file or directory

[root@localhost ky_volume]#

然后我把gcc给卸载了

yum remove gcc

[root@localhost ky_volume]# yum remove gcc

Complete!

然后我再重装gcc和g++（其实貌似也可以不用卸载gcc，直接安装g++就可以了）

yum install gcc

yum install gcc-c++

然后查看gcc和g++的版本

gcc -v

g++ -v

[root@localhost ky_volume]# g++ -v

然后我再执行编译，通过了
