Hi! Wow, this is my lost first post! I didn't found it after posting, so I've made a new one here https://groups.google.com/forum/embed/?place=forum/beagleboard&showsearch=true&showpopout=true&showtabs=true&hideforumtitle=true&parenturl=http%3A%2F%2Fbeagleboard.org%2FCommunity%2FForums#!category-topic/beagleboard/beaglebone-black/bZZ2Ly6FLFo . I also didn't receive any email notification. Very strange.
Nonetheless, I've just set up a blog and wrote down a tutorial to set up Qt 4.8.6 with hardfp. You can find it here: http://embedded.von-kannen.net/2014/05/21/qt-4-8-6-on-beaglebone-black/ Related to your idea with the patch: yes, I've applied the patch already, but that's also not working. Just found out that there are is a newer patch at http://pastebin.com/p88wce2f. After applying this one (and little changes in mkspecs) the 2dpointer example gave output on the OpenGL side (but I had to run it without "-display powervr"). Every else example doesn't work, either with -display powervr nor without it. Do you know something more about it? Maybe you could try a little bit? Currently I'm feeling like I'm the only one who is trying to archive duly hardware acceleration in Qt. Btw, I archived to run SGX in kernel v3.8.13 and got rid of kernel v3.12 (don't like it because of the bad cape support) Am Mittwoch, 21.
