Hey no prob...one thing I forgot to mention is that we saw some weird behavior
with Qt/Embedded after getting it to compile.
When trying to run any Qt program it would segfault in
QLinuxFbScreen::useOffscreen().
If you look at the code for that member function in the Qt source, there's
nothing that could possibly cause a segfault. It turns out it's caused by a bug
in GCC for ARM that clobbers a register under certain (rare) conditions, and I
believe it exists in gcc 4.1 and up.
Andy's instructions include a patch for it for gcc 4.3.3 (adapted from the
patch attached at the bottom of
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39429), I'm not sure how difficult
it is to backport the patch to earlier versions. After applying the patch Qt
works excellently.
