1. 问题的提出
在安装extundelete的过程中,发现在configure过程中,出错了,具体的错误信息如下:
-
configure:2865: g++ --version >&5
-
./configure: line 2867: g++: command not found
-
configure:2876: $? = 127
-
configure:2865: g++ -v >&5
-
./configure: line 2867: g++: command not found
-
configure:2876: $? = 127
-
configure:2865: g++ -V >&5
-
./configure: line 2867: g++: command not found
-
configure:2876: $? = 127
-
configure:2865: g++ -qversion >&5
-
./configure: line 2867: g++: command not found
-
configure:2876: $? = 127
-

-
./configure: line 2920: g++: command not found
-

-
configure:2960: result: no

See `config.log' for more details
经过分析,发现其中的关键错误信息是:
g++: command not found
g++马上就脑补为gc++的编译器是不是没有安装呀? 估计是的,按图索骥,安装看看。
2. 安装以及解决
由于本人使用的OS环境为centos, 其默认的包管理工具为yum, 故按照依赖包:
-
yum -y update gcc
-
yum -y install gcc+ gcc-c++
执行上述命令之后,可以返现gcc相关命令都按照成功了,故问题解决。
3. 总结分析
默认情况下,centos并未按照gcc相关的编译命令,如果在安装软件之时,有时候需要从源代码编译开始,进行安装;此时就需要gcc的命令支持。
