Exception description
I have configure:error:c++ compiler cannot create executables issue during the installation process
This later looked at the relevant information only to find that the GCC components are not fully loaded, I previously installed GCC is to notify the Yum way:
Yum Install gcc gcc++
In this case there are still components that are not fully installed. A second execution of this command will solve the problem.
Yum Install gcc gcc-c++ gcc-g77

There should be no problem with that.
