1. The question was raised

During the installation of Extundelete, it was found that during the configure process, there was an error, and the specific error message was as follows:

2. configure:2865:g++--version >&5
4. ./configure:line 2867:g++: Command not found
6. configure:2876: $? = 127
8. configure:2865:g++-V >&5

18. configure:2876: $? = 127
20. configure:2865:g++-qversion >&5
22. ./configure:line 2867:g++: Command not found
24. configure:2876: $? = 127
26. Configure:2896:checking whether the C + + compiler works

76. configure:2967:error:c++ compiler cannot create executables
78. See ' Config.log ' for more details

After analysis, it is found that the key error messages are:

 g++: command not found

g++ immediately to the brain to complement the gc++ compiler is not installed AH? Estimate yes, retrace, install look.

2. Installation and resolution

Because I am using the OS environment for CentOS, the default package management tool is Yum, so follow the dependency package:

1. YUM-Y Update gcc
2. Yum-y Install gcc+ gcc-c++

After executing the above command, you can return to the GCC related commands in accordance with the success, so the problem is resolved.

3. Summary analysis

By default, CentOS does not follow the GCC-related compilation commands, and if, at the time of installing the software, it is sometimes necessary to install it from source code compilation, then GCC command support is required.
