Q. How do I install all developer tools such as GNU GCC C/C++ compilers, make and others, after installing CentOS from a shell prompt?

A. You need to install 'Development Tools' group. These tools include core development tools such as automake, gcc, perl, python, and debuggers:
=> flex
=> gcc
=> redhat-rpm-config
=> strace
=> rpm-build
=> make
=> pkgconfig
=> gettext
=> automake
=> strace64
=> gdb
=> bison
=> libtool
=> autoconf
=> gcc-c++
=> binutils and all dependencies.

Open termianl or login over ssh session and type the following command as root user:
# yum groupinstall 'Development Tools'
