What Is pkgs.org
This section provides a tutorial example on how to use pkgs.org Website to search, find and install software packages on Linux systems.
What Is pkgs.org? - pkgs.org is Website that provides you with the simplest method of browsing, searching and downloading the newest versions of Linux and Unix packages.
pkgs.org indexed thousands of software packages for different flavor of Linux systems, versions and CPU architectures.
In order to use pkgs.org effectively, you need to prepare 2 sets of information:
1. Technical Info of Your Local System: OS name/version and CPU architecture. You can get them with the "hostnamectl" command on CentOS systems:
herong$ hostnamectl Operating System: CentOS Linux 8 (Core) CPE OS Name: cpe:/o:centos:centos:8 Kernel: Linux 4.18.0-147.el8.x86_64 Architecture: x86-64
2. Name and Version of the Software Package You Are Looking for, like:
Name: leptonica Version: 1.76.0
Then you can to go https://pkgs.org, and search for "leptonica". You should see the following matches in the "CentOS 8" section:
leptonica-1.76.0-2.el8.aarch64.rpm leptonica-devel-1.76.0-2.el8.aarch64.rpm leptonica-1.76.0-2.el8.armv7hl.rpm leptonica-devel-1.76.0-2.el8.armv7hl.rpm leptonica-1.76.0-2.el8.i686.rpm leptonica-1.76.0-2.el8.x86_64.rpm leptonica-devel-1.76.0-2.el8.i686.rpm leptonica-devel-1.76.0-2.el8.x86_64.rpm
Based on my system information, I need to install the following two packages:
leptonica-1.76.0-2.el8.x86_64.rpm C library for efficient image processing and image analysis operations -- The binary package leptonica-devel-1.76.0-2.el8.x86_64.rpm Development files for leptonica -- The source package
Click on the binary package name, leptonica-1.76.0-2.el8.x86_64.rpm, to see download and installation instructions.
... Download http://mirror.centos.org/centos/8/PowerTools/x86_64/os/Packages \ /leptonica-1.76.0-2.el8.x86_64.rpm Install Howto # dnf --enablerepo=PowerTools install leptonica
I see two options to install it:
Always use the "dnf" option to install software packages. It is more reliable and safer.
