gcc install question for CentOS 5.6

KingSalibah · 11-21-2011, 02:12 PM

I know very little about linux.
I am running a web server on a Centos 5.6 server.
I was trying to install git, but I can't because I don't have gcc installed.
So, I tried to install gcc, but then I get a massive amount of prerequisities like glibs then kernal, etc. and I am like whoa! Not so fast!

All I want to do is install git!

The latest versions of gcc are beyond 5.6. Is there a simple installer for gcc that includes everything that doesn't require a full OS update?

Or is there another way to install git?

I have a folder called /usr/libexec/gcc/x86_64-redhat-linux/ which has a 4.1.1 and a 4.1.2 folder with cc1 inside, but when I typed "rpm -ql gcc" it said package gcc is not installed.

I have been at the brink of giving up for about 10 hours. But I keep trying this and that. Are there some simple solutions here?

If you are still on 5.6 then you're looking at about 100mb of updates to get to 5.7. This is totally normal and in fact is a Good Thing because you'll get the latest bug fixes and security patches.

I recommend updating your system regularly. If this is an important production server then it's prudent to have a test system too.

Here are some resources to help you get started with CentOS:

Thanks. I am a little concerned in that the server is not connected to the Internet. It is a intranet server. I suppose I need to check into this. I don't think it is quite simple for a newbie like me to do a new OS upgrade.

Wow, you are a fast reader, you breezed right through all those "How To's" in only 14 minutes!
Let me know if you have any more questions, good luck.

Is it possible that CentOS doesn't have gcc installed? Is there no other way to install git without gcc installed?

Thanks for your suggestion that I should upgrade from 5.6 but I don't see that the links you provided assist me with that.

While I realize I know very little about CentOS, I am trying to solve my current problem before I go off onto another lengthy study, among the dozens of things I am already deeply delved into study-wise.

How are you trying to install git? Do you know what gcc is? If you are trying to install from a tarball with source code then thats why you need gcc to compile it. GCC, the GNU Compiler Collection is a C language compiler. Have you used YUM to try and install needed tools?

Test if you have GCC install type in terminal aka command prompt

Code:

gcc -v

It should give you the version of gcc if installed.

Yes, I was trying to install git with a tar.gz file. I suppose if there is an rpm version, that would be simpler.

gcc -v says "bash: gcc: command not found."

I couldn't find an rpm on git's site, but jmc1987 gave me the idea of looking further. I found the packages at http://pkgs.repoforge.org/git/. Yay!

I am not sure what to do about 5.6 upgrade. I would need to find a good tutorial about that. As to gcc, I thought it would be installed already and then thought it would be easy to install, but I wasn't so lucky.

to update your system you would simply run
# in front means root
$ means user account and execute it

Now to update to 5.7

Code:

#yum update

Now I am assuming you have a x86_64 based on the libs you linked on first post.

Now setting up rpm forge repos

Code:

# rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
$ wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm
$ rpm -K rpmforge-release-0.5.2-2.el5.rf.*.rpm
# rpm -i rpmforge-release-0.5.2-2.el5.rf.*.rpm

Installing git

Code:

# yum install git

Now in my opinion you should disable this repo so you don't get any packages that may break your system.

Your approach is correct, let's forget about upgrading to 5.7 for now and address your immediate problem of installing git.

The package manager (tool for installing software) in CentOS is called 'yum' so start here:

http://www.centos.org/docs/5/html/yum/
http://www.centos.org/docs/5/html/yu...ompackage.html

Because this machine is not connected to the internet, you may wish to set up a local repository. This could be a local mirror somewhere on the network or as simple as a copy of the CentOS DVD.

(edit) Weird if git is not in the centos repos but if so jmc1987 has some advice above.
