I'm trying to ascertain whether its possible to compile a set of .as / .swc files to a swf from a Linux (specificity Ubunto) command line.
Ideally it would be a free solution.
any suggestions would be fantastic.
yep, use the mxmlc program that comes with the free flex sdk. this is essentially what flashdevelop is doing. you can get more info on it here: http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf69084-7fcc.html
