Flash develop or some kind of compiler for linux?

so i have recently started using linux on my new laptop, causee it came with vista and i quickly grew tired of it, linux is actually pretty cool! i have been playing with it for a couple of days , getting the hang of using gimp and open office draw for making graphics and such, but there is one large part of my computing world missing, no flash compiler!!! ahhh!!!

from what i have read flashdevelop isn’t compatiable… does any one know an alternative?? also i would be nice to find something to animate swf files with but im not as worried about that?
