Software Installation Process on Linux (How)

mfdarvesh · 04-03-2008, 04:18 AM

I am still Newbie to Linux, using CentOS 4.4 for last two months. Installation Process on Linux seems more difficult than Windows, specially analyzing dependencies. Like few days before I searched web for downloader and found D4x, now downloaded its RPM and trying to install, it gives a long list of files missing, now how to can I search each of them, it is very difficult to find all.

Similarly, I tried #yum install d4x, same result found, is it some command that can automatically download all dependencies ..

yum should get dependencies on your behalf... as long as it knows the repositories you are trying to install from.

You typically have to download the RPM for the repository server you are getting your RPMs from.

Once installed, a simple "yum install whatever" should query that repository as part of the search and get all dependencies along with it.

For most common applications--using the package manager--the dependencies will be handled automatically. Always try the package manager first.

If you want to install SW that is not available in your package manager, then--yes--you have to track down whatever it needs.

d4x is available in the package manager on two systems here: PCLinuxOS and Arch Linux.

Once you get used to a good package management / repository system, you will find that installing SW on Linux is actually much easier than on Windows.

Thanks, where I can find package manager and how can I use that. Moreover, rpm -ivh can install or not?

Check 'man yum'. It should be installed by default on your Centos system. rpm does not resolve dependencies. Yum is a package manager.

Isn't there an Add/Remove Software item on the "Applications" menu?

mfdarvesh · 04-05-2008, 02:41 AM

LazLow, I try "yum install D4x" but it does not work at end it says nothing to do.

No Jay73, No add remove in Application menu is available.

Is there a line in there that says "No package D4x available."? If so that means that the particular package is not available from the repos you are using. If there is no such line that would indicate that it is already installed.

Where did you get this rpm from? Please post link.

Thanks, Lazlow, please tell me the easiest way to install D4x on CentOS, I think rpmfin.net from where I download the rpm.

Again look at "man yum". In this case you are looking for localinstall.

Try this:

Open up a text editor and paste in the following:

Code:

[fc6-base]
name=Fedora Core 6 Base
mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=core-6&arch=$basearch
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-extras
gpgcheck=0

[fc6-updates]
name=Fedora Core 6 Updates
mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=updates-released-fc6&arch=$basearch
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-extras
gpgcheck=0

[fc6-extras]
name=Fedora Core 6 Extras
mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=extras-6&arch=$basearch
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-extras
gpgcheck=0

Save out this as a file inside the /etc/yum.repos.d directory, name the file "FC6.repo"

Then try

Code:

yum install d4x --enablerepo=FC6.repo

I would be careful mixing distro repos. Centos5 was based on FC6. I think Centos4 was based on FC3(?). So even if you wanted to try and use Fedora packages on Centos you would want to stick to the version that it was based on. Newer versions will probably have newer dependencies and mixing and matching can bring down a system pretty fast.
