In the past, when I was looking for software for which no native Slackware package was available, I used to compile the software from source and install it as such (in /usr/local/…). This usually works well, but I then found out you can build your own Slackware packages. This is much more convenient, as it integrates nicely with the Slackware package management system. And once you have the packages, you can easily deploy them on multiple machines.

 
All the packages I made so far, are available on the next link: Slackware packages.
Note: these packages are for Slackware x64 only.

 
The latest 2 packages are :

 

Enjoy 😉
