Flash/Flex Development on Scientific Linux

If you want to use a linux box for testing/developing AS3/Flex apps, you are likely to come across some obstacles:

• Flash Builder is no longer supported on Linux. The last available version is FB3.
  (ok, there’s the barely legal FB4Linux, too….)
• Air Development is no longer supported on Linux. Air 2.7 SDK is only available for Mac and Windows:

• Air runtime is no longer developed for Linux.

• the ADL file that ships with the Flex 4.5 SDK is built for Mac. The Linux Air package is built for Flex 4.0.
• …and so on.

That said, it is possible to set up a stable development environment on Linux.
FDT is still supported on Linux and the Flex 4.5 SDK + Air 2.6 SDK can be tweaked to work on linux.
