The previous posts tried to explain that because you installed RHEL 5, but probably are not paying a subscription, you cannot use the RHEL repositories for installing software. Since Centos 5 aims, and is pretty successful, at being 100% binary compatible with RHEL 5, you can change the software repository used by the yum package manager to refer to Centos 5 sites instead of the official RHEL 5 sites with minimal, if any, disruption. The following site shows how to do this. It is merely a matter of changing the contents of the file stored in /etc/yum.repos.d/ using a text editor:

http://www.centos.org/modules/newbb/...?topic_id=7905

You will then be able to issue the yum commands to install all the normal software packages as suggested in the posts above.

Hope this helps. Keep posting with questions and problems you experience.

The CentOS people take advantage of the fact that Red Hat releases their software under the General Public License to just blatantly copy all the source code for you free use. They just have to remove the other aspects of the Red Hat's intellectual property that are not covered by the GPL (trademarks). They host the blatantly copied source code on their own servers.

This is why you need to change the contents of the file in the /etc/yum.repos.d/ directory. You need to tell yum to stop looking at the offical RHEL servers for software and instead look at Centos' servers.

i have downloaded a rpm package for gcc named gcc-4.3.1-6.ppc.rpm
i typed rpm -i gcc-4.3.1-6.ppc.rpm on the command prompt and got the following error....

error: Failed dependencies:
binutils >= 2.17.50.0.17-3 is needed by gcc-4.3.1-6.ppc
cpp = 4.3.1-6 is needed by gcc-4.3.1-6.ppc
glibc-devel >= 2.2.90-12 is needed by gcc-4.3.1-6.ppc
libgcc >= 4.3.1-6 is needed by gcc-4.3.1-6.ppc
libgomp = 4.3.1-6 is needed by gcc-4.3.1-6.ppc
libgomp.so.1 is needed by gcc-4.3.1-6.ppc

how do i install these subordinate things required

Ist you will need to have dependencies file to install gcc++ u can find it from ur linux CDs or DVDs or type file name in google which u needed and u will find it or go to rpmfinder.net

Ok, rpms come in 4 basic types for each distro and version.

.src.rpms= source rpms
.ppc.rpms for ppc computers (macs until recently)
.i386(or i686) rpms for 32bit computers or 32bit OS running on 64 bit computer.
.x86_64 (or some variant thereof) for 64 bit computers.

You probably need the i386 rpm depending on what you have installed.

i have the RedHat Enterprise Linx 5 so which package do i reqire for that the .i386??

Yes, but there is a .ppc rhel5, .i386 rhel5, and a .i686 rhel5.

Post the results of "uname -a". That should tell us.

this is the result of the uname -a command

Linux localhost.localdomain 2.6.18-8.el5 #1 SMP Fri Jan 26 14:15:21 EST 2007 i686 i686 i386 GNU/Linux

Ok, that says that you are using the 32bit version. So you need to use rpms with i386 (or i586 or i686) in the name.

i downloaded the package gcc-3.2.2-5.i386.rpm

now when i run the command rpm -i gcc-3.2.2-5.i386.rpm

i got the following error

warning: gcc-3.2.2-5.i386.rpm: Header V3 DSA signature: NOKEY, key ID db42a60e
error: Failed dependencies:
cpp = 3.2.2-5 is needed by gcc-3.2.2-5.i386
glibc-devel >= 2.2.90-12 is needed by gcc-3.2.2-5.i386

now i have the following packages on my desktop

gcc-3.2.2-5.i386.rpm

the above package required something more so i downloaded the following:

glibc-devel-2.2.93-5.i386.rpm
cpp-3.2.2-5.i386.rpm

now how do i proceed from here

this is the error when i tried installing gcc-4.1.2-42.el5.i386.rpm

where can i download this file

glibc-devel-2.2.90-12

only this file is causing a lot of dependency problem

go to this website u can download devel file from here

http://rpm.pbone.net/index.php3/stat...ch/glibc-devel

Is pursuing dependencies worth the effort as opposed to getting yum working? Even if this application is installed via manual rpm'ing, wouldn't yum pay off considering all the future packages to be installed? Not meaning to deride the progress made...

Ehawk is right. This is why they invented yum. I am going to guess that Centos has the more current version of glibc (which is why your system is asking for the older version of the -devel). All these dependencies are interconnected. If you change just one piece you may have to change ten more just to make sure that the mesh of the system is maintained (thus yum).
