[QF-Test] HOWTO: Set up and run a 32bit JRE and Firefox on Ubuntu 14.04 64bit
Hi everyone, we know that it is becoming increasingly difficult to work with a 32bit JRE and Firefox on modern 64bit Linux systems. While we're working on improving this situation, here's a short HOWTO for the recently released Ubuntu 14.04. Ubuntu now has a very good and clean solution for installing every package in a 32bit version also, so fortunately the solution is straightforward: 1. Installing a 32bit JRE ------------------------- First you need to activate support for 32bit packages: sudo dpkg --add-architecture i386 sudo apt-get update For a 32bit JRE you can either use apt to install the 32bit version of OpenJDK sudo apt-get install default-jre:i386 and switch to using this 32bit JRE as the default by typing sudo update-alternatives --config java and selecting the 32bit version. Alternatively you can download and install a 32bit JRE or JDK from Oracle, e.g. jre-7u55-linux-i586.tar.gz via http://www.oracle.com/technetwork/java/javase/downloads/index.html Now create a directory and unpack and rename the JRE: mkdir ~/jre32bit cd ~/jre32bit tar xfz jre-7u55-linux-i586.tar.gz mv jre1.7.0_55 jre If you only plan to install a JRE this way and nothing else you'll probably need to install the libraries libc6:i386 libncurses5:i386 from list below. 2. Installing a 32bit Firefox ----------------------------- If you install a 32bit Firefox with apt it will replace the 64bit version instead of creating an alternative. Since it is preferable to use different browsers for testing and personal use (auto-update etc.) it is advisable to proceed as follows instead: - Download a 32bit Firefox, e.g. ftp://ftp.mozilla.org/pub/mozilla.org/firefox/releases/29.0/linux-i686/en- US/firefox-29.0.tar.bz2 - Create a directory and unpack Firefox: mkdir ~/ff32bit cd ~/ff32bit tar xfi firefox-29.0.tar.bz2 - Now you need to get the necessary 32bit libraries installed: sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 libxext6:i386 libxrender1:i386 libxt6:i386 libxtst6:i386 libxi6:i386 libgtk2.0-0:i386 libxxf86vm1:i386 libasound2:i386 libdbus-glib-1-2:i386 3. Running QF-Test ------------------ QF-Test will start with the 32bit JRE if you used the first approach and installed a 32bit system JRE as the default alternative. Otherwise simply start QF-Test with qftest -java ~/jre32bit/jre/bin/java Run the quickstart wizard for a web application in a browser and point it to your 32bit Firefox for the Mozilla installation directory. Note that you can't use ~ here so it has to be of the form /home/<username>/ff32bit/firefox Best regards, Greg -- Gregor Schmid E: gregor.schmid@?.de T: +49 (0)8171 38648-11 F: +49 (0)8171 38648-16 Quality First Software GmbH | www.qfs.de Tulpenstr. 41 | 82538 Geretsried | Germany GF Gregor Schmid, Karlheinz Kellerer HRB München 140833
