Never Back Down

Q. I have Red hat enterprise Linux 5 installed on one of the production server. However there is no c compiler installed. I need to compile few applications on this box. How do I install C or C++ compiler on Red Hat Enterprise Linux 5? Where can I get / download compile package?

A.In order to compile and use c/c++ under Linux you need following packages
=> autoconf : GNU's Autoconf is a tool for configuring source code and Makefiles.
=> make/automake : A GNU tool for controlling the generation of executables and other
non-source files of a program from the program's source files.
=> GNU GCC C compiler (gcc) : The gcc package contains the GNU Compiler Collection version 4.1
=> GNU GCC C++ compiler (gcc-c++): This package adds C++ support to the GNU Compiler Collection.
