I downloaded Angstrom from "here(http://www.angstrom-distribution.org/demo/beagleboard/)":http://www.angstrom-distribution.org/demo/beagleboard/ .
Is there a way to find the environment they used to build it?
When I used another board (NGW100) with buildroot they also supplied the sdk.[/quote]
Yes, Openembedded …
I know, the initial start with developing on ngw100 is a bit easier. Main reason - the default ngw-image has a few megs, while on a beagle, you have a complete distribution with package manager, X11, mplayer, etc. Angstrom-Demo is 275M, and to compile it you need ... well ... the complete build env.
Just start with openembedded, configure for beagle and angstrom, and try to compile something simple, like nano. If that works, you already have the compiler and all. Then, you can try qt ...
Concerning qt, IIRR, oe/angstrom compiles qt several times, you need it once native for the tools (moc, qmake, etc), and then you have the embedded and the x11-free variant. I'm not sure what version is current in OE, now, I updated to 4.5.3 some time ago. Oh, I use the x11 version b/c I want to run more stuff than just qt apps ....
