Chromium is an open source web browser from Google. It is based on the WebKit rendering engine and is the upstream project for Google's popular Chrome Web Browser.
Keep in mind that Chromium is the testing branch of the Chrome web browser, and is not recommended for mission-critical systems. Consider using Google Chrome or Mozilla Firefox for production systems.
This tutorial explains how to install the latest Chromium build on Slackware and automate the process of updating it regularly. It is aimed at users on a personal desktop or laptop, especially on a single-user system.
While the slackbuilds.org project provides excellent quality build scripts for Chromium, downloading 140MB+ source code and doing compilations that often take more than a couple of hours to complete is generally not feasible for people with laptops, slower computers or slow internet connections.
Therefore, this guide aims on how to automate the process of installing and updating Chromium using daily binary builds that are much smaller in size and take up negligible resources for the install and update process, thus helping the user always run the latest and greatest builds without the hassle of downloading and compiling the source code.
Chromium depends on
ORBit2, and these should be installed first. Newer versions may also need the PAM library.
The above mentioned dependencies are included in the extra/ tree of Slackware 13.37, so these can be simply installed by :
# slackpkg install GConf ORBit2 google-chrome-pam-solibs
# sbopkg -i 'ORBit2 GConf'
# installpkg ./google-chrome-pam-solibs-1.1.3-x86_64-1.txz
Getting and installing the latest Chromium build
Google maintains a repository of daily chromium builds that you can get from here (32bit) or here for 64 bit. Scroll down to the bottom and navigate to the latest build directory, and download the 'chrome-linux.zip' file there.
Extract the zip file to a place of your liking (I like to keep mine in /home/username/soft), and run the 'chrome-wrapper' binary that will run Chromium and also generate a 'chromium-dev.desktop' file in /home/user/.local/share/applications/ and a Chromium entry will appear in your KDE or Xfce menu. Copy that file to your desktop if you prefer a desktop shortcut.
To upgrade Chromium, just download the latest zip file and extract it where you previously did, overwriting the previous files.
Automating the Process
The following script helps to automate the process of installing and upgrading Chromium. Edit the
INSTALLDIR variable to your liking - that is the place where chromium will be installed. Its recommended to keep it in a folder in your home directory to make it easy to manage. make sure the folder exists before running the script, or the script will fail.
#!/bin/bash # Installation directory - change this to a directory of your choice # Please make sure the directory exists first, or the script won't work INSTALLDIR=$HOME/soft # Determine the architecture of the machine in use and set variables accordingly if [ -z "$ARCH" ]; then case "$( uname -m )" in i686) ARCH=i686 ;; *) ARCH=$( uname -m ) ;; esac fi if [ "$ARCH" = "i686" ];then DIRSUFFIX="" elif [ "$ARCH" = "x86_64" ]; then DIRSUFFIX="_x64" else echo "The ARCH should be either i686 or x86_64. Exiting." exit fi # Determine the build number of the latest build LATESTBUILD=$(curl http://commondatastorage.googleapis.com/chromium-browser-continuous/Linux/LAST_CHANGE) # The URL to download from CHROMEURL="http://commondatastorage.googleapis.com/chromium-browser-continuous/Linux"$DIRSUFFIX/$LATESTBUILD/"chrome-linux.zip" cd $INSTALLDIR if [ -e chrome-linux.zip ]; then # Check to see if `chrome-linux.zip` already exists mv chrome-linux.zip chrome-linux.zip.old # if it does, rename it to chrome-linux.zip.old as backup fi # in case the current build has problems wget -O chrome-linux.zip $CHROMEURL unzip -u -o ./chrome-linux.zip
To automate the process, first save the script as chromium-update.sh and add it to your users's cron jobs. Here is an example on how to set it up :
$ cd $HOME $ mkdir .cron $ cp ./chromium-update.sh ./.cron/ $ chmod a+x ./.cron/chromium-update.sh $ crontab -e
Add the following to your crontab :
# Run daily cron job at 13:20 every day: 20 13 * * * ~/.cron/chromium-update.sh 1> /dev/null
This will run the script at 13:20 every day. See
man crontab for more on how to customize your cron jobs.
