I'll pipe in here with some simple points since I routinely/exclusively work with Flex on Linux. I don't do flash/flex dev on Windows at all.
I'm still using Flex 4.6 at the moment. I plan on switching to Apache Flex in the coming weeks and can provide an update to the mailing list then, if people are interested how it goes. I don't expect too many difficulties switching over (famous last words?), but know I won't be able to use the auto-install that has been created. However, for 4.6 I basically just needed to unpack the tar file and that was pretty much it, (I think... been a while) so this gives me some measure of confidence. Dependencies may be fun, but I hope I can just copy some of these across (fingers crossed!), assuming they haven't changed radically. I use IntelliJ IDEA as my IDE for flash/flex and it works extremely well on linux, including debugging (see below). Flash player 11.2 plugin and standalone still work very well on Linux. Chrome for linux is running the latest flash player and also works quite well. I'm currently at v11.5.31.137 via the pepper plugin. ie: Flash for Linux is not actually dead as people often say... you just need to use Chrome (or stick with the v11.2 plugin). For debugging I use the standalone flashplayerdebugger for Linux. This is stuck even further back (v11.1), but this has not caused me any dev problems at all (as of yet). AIR is another story. The "proper"/supported Linux version for AIR (2.6) is now pretty ancient, but the new one works through Wine... or at least I got it working several months back, anyway. Getting it to work on a 64-bit system is/was a bit of a nightmare, though. Definitely not for the faint of heart. I don't use AIR and it was really painful , so I don't have a currently functioning version to speak more to than that. Hopefully some of that helps someone, even if it's just letting fellow Flex-on-Linux devs know they aren't completely alone. :) Russ
