Step-By-Step: Installing Flex Builder 3 under Ubuntu

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 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 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 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 🙂
