Qt5 application with eglfs

EinarMar — Tue, 10 Dec 2013 11:19:02 GMT

I have cross-compiled Qt5 with EGL support and now when I'm trying to run an application from the Qt examples like:

#> ./hellogl_es2 -platform eglfs

it returns straight away without any notice. The return code is 1.

Even with other platform plugins the behavior is the same.

Is this a known issue to someone or do I need to provide something more in order to explain myself.

regards

Einar

Einar,

when there is no useful (or no log at all) log, I run the app with 'strace' (strace ./hellogl_......). Give it a try and you may find the reason.

Hi Leonardo

I usually run with strace and I've tried it here but it didn't give me any further insight.

I will attach a file with strace output so you can look. Maybe you will be able to spot something.

Is there anyone willing to look into the strace file. I'm not sure what is happening just by reading it so I would need some help on this.

My program is not running 'main' and exits with status 1 without any printouts.

Hope somebody can look into the strace output hellogl_es2_strace.

I have figured out what was causing this problem of my Qt5 application not starting and exiting with status 1. It was one library (libicudata.so.52.1) that was not hard-float compiled which caused the linker to exit without any other warning then status 1.

After that was fixed a was able to start the application but it crashed shortly after being started and the reason was incorrect EGL binaries. I was using some version of those libraries acquired from this forum earlier this year.

Now I downloaded from here: http://repository.timesys.com/buildsources/g/gpu-viv-bin-mx6q/gpu-viv-bin-mx6q-3.0.35-4.0.0/ and then my application was not crashing.

My Qt5 application is still not able to run because it complains about: EGL Error : Could not create the egl surface: error = 0x300b

The application is executed like: hellogl_es2 -platform eglfs

If anyone has some idea about that I would appreciate the input.

Hi Einar, it would be good if you create a new discussion thread with this last issue.

Hi Leonardo, see here: EGL Error creating egl surface, error = 0x300b
