An IDE is a tool for editing, you could use anything. Hell, even

Code:

cat > mycode.cpp
...
...
<ctrl+d>

As for compiling, which I think is what you're wanting to know, try our old friends at google: http://www.google.co.uk/search?hl=en...+linux&spell=1

Which distro of Linux are you running?

You will need a to have a number of packages installed, which you can probably get through your distro's package manager (apt-get or Synaptic in Debian based distros, yum in Red-Hat based ones). Debian has a meta-package called build-essential, which installs (among others) libc6-dev (C and C++ developement library) g++ (the GNU C++ compiler), make (for building complex programs), etc.

Eclipse may also be available via your package manager, but you can also get it from the site of the Eclipse foundation. It's written in Java, so you'll need at least Java runtime (and, I think, the Java development kit) installed, first.

Use the g++ compiler and any plain text editor, the better ones offer syntax highlighting for languages including C++.

1) su
2) yum install gcc-c++
.. will provide the c++ compiler.
And the library used for c++ programs (= libstdc++)

3) yum search eclipse
will show all eclipse packages.
4) yum install eclipse*
will install all eclipse packages.
..

As already stated, you use the package manager. This is in your menus--probably called something like "install software". Since you are using RedHat Enterprise, you will need to register with RedHat Network.

If whoever installed RHEL paid for support and registered, then the package manager software should work. If paid for but not yet registered, I have no clue, but you should be able to find out next steps from RedHat.

If you haven't paid for support, I suggest you (the OP) read my recent post about newbie RHEL questions:

Probably you're using the wrong distribution for your purposes. Probably it will take less effort to start over with a different distribution than to push forward with RHEL. Obviously, I don't know your specific situation.

i am using red hat enterprise. in order to install c n C++ do I have to download libc6-dev package and then install it through yum?? similarly do I have to install gcc compiler??

No, you do not download system packages in Linux.
All packages are automatically downloaded and installed,
when you choose the package in the "Package Manager" or
by using the command line 'package handling tool' = 'yum'.
All dependencies are also automatically installed.

Example : # yum install gcc-c++ :

libstdc++ , glibc-devel , glibc-headers , etc.
will be automatically installed too.

Did you activate your Redhat account ?
Redhat EL5 is commercial, and not usable without an account.
If you don't want to pay : The free version of EL 5 is CentOS 5.5 ..
