A common question asked is on how to install Adobe’s Flex Builder under Ubuntu. Well, Ill detail the steps I took to get this beast running under my Ubuntu distribution, which is 9.4. These steps should be quite straight forward, but as a reference to those who get stuck, this might be of use:
1) Download version 3.3.2 from http://archive.eclipse.org/eclipse/downloads/. Unfortunately as of current, Flex builder does not work under eclipse 3.4 (Ganymede). So make do with an older version.
2) Unzip/Extract to your home directory. Open up eclipse to make sure it’s working fine. If it all looks good, proceed to step 3.
3) Go to http://labs.adobe.com/technologies/flex/flexbuilder_linux/ and download the latest Adobe flex builder linux alpha. Ensure the bin file has execute permissions.
4) In terminal, run ./flexbuilder_linux_install_a4_081408.bin where the file is located. Follow the on-screen installation instructions. My suggestion is to place the flex builder installation under : /home/username/opt/flex/flexbuilder. Make sure you also point the eclipse installation to where you put the eclipse folder (such as /home/username/eclipse).
That should be it. Now to run flex builder, you go to the directory where you installed Flex Builder (such as ~/opt/flex/flexbuilder) in terminal, and run ./Adobe Flex Builder.sh or whatever the sh file is called within there. To make things easier for you in the long-run, just create a shortcut to it on your desktop or panel-bar.
Let me know if it works or doesnt work for you and I can see what we will do 🙂
