How to install package by Slackbuild script on Slackware

So,installing package on Slackware is pretty different then other distro.You need to work little more to do that .Fortunately some great guys have done all the hard work for us to do thing in minimal way.In this post I will show you how you can install any package from the Slackbuild.org repository with the help of Slackbuild script.

So I a going to install a forensic package called “chkrootkit” from that repo and installed in Slackware.First get into this page chkrootkit to get the source of it as well as Slackbuild source too.

Okay ,once obtain those then please untar the SlackBuild one and it should look like below:

bhaskar@Slackware:~/Downloads/chkrootkit$ ls
README chkrootkit.SlackBuild chkrootkit.info chkrootkit.tar.gz slack-desc


Yes, that tar file inside that directory not come with that Slackbuild source. It’s the other one I have move to that directory,because SlackBuild script require the source of the package should be inside the SlackBuild dir.

Now, next step to execute the SlackBuild script like below:


bhaskar@Slackware:~/Downloads/chkrootkit$ sudo ./chkrootkit.SlackBuild

Slackware package maker, version 3.14159.

Searching for symbolic links:

No symbolic links were found, so we won’t make an installation script.
You can make your own later in ./install/doinst.sh and rebuild the
package if you like.

This next step is optional – you can set the directories in your package
to some sane permissions. If any of the directories in your package have
special permissions, then DO NOT reset them here!

Would you like to reset all directory permissions to 755 (drwxr-xr-x) and
directory ownerships to root.root ([y]es, [n]o)? n
