Hi again;

In Raspberry Pi;

Qt5 is working but when i created gui application, App is starting but only white screen showing. I searched, buildroot can’t transfer rpi-userland files. That is about Eglfs. Is the problem about this ? How to fix it ?

Output of `strace ./try3 -qws` : [http://pastebin.ca/3177998](http://pastebin.ca/3177998)
