eglfs + framebuffer - display issue

python74

Re: Qt & framebuffer
Hi everyone
I found recently topic about refreshing framebuffer. Maybe I have similar problem. Im trying to run Qt app on Allwinner A20 (Olinuxino Micro). It looks like app shows 1 frame and stops refreshing framebuffer. No problems or errors report in console, no problems with terminate from console, no premature exit with error code etc. In desktop enviroment is showing up 1 frame and desktop repainting on app layer. WTF? Anyone had similar problem?
PS. sorry for my English

Hi and welcome to devnet,

You should also add which version of Qt you are using and to target what platform ?

python74

Hi
Qt 5.2.1 to olinuxino micro (Allwinner A20)

SGaist

Can you first update to a more recent version of Qt ? 5.2.1 is more than old, the current version if 5.9.1

python74

Right now i'm trying to update to Qt 5.9, but i have some issues with math.h compatibility between device and Qt. When I'm done I'll tell about effects.

python74

I'm trying to build Qt5.9 enviroment but configure cannot pass eglfs option:
ERROR: Feature 'eglfs' was enabled, but the pre-condition '!config.android && !config.darwin && !config.win32 && features.egl' failed.
Any idea?

SGaist

What's your complete configure line ?

python74

./configure -release -opengl es2 -nomake examples -nomake tests -opensource -confirm-license -device olinuxinoA20 -device-option CROSS_COMPILE=~/qt5.9-arm-compile/gcc-linaro-7.1.1-2017.05-i686_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- -sysroot ~/qt5.9-arm-compile/sysroot -prefix /usr/local/qt5.9 -extprefix ~/qt5.9-arm7 -hostprefix ~/qt5.9-arm7-host -eglfs -v

in sysroot are present needed includes EGL, GLES, GLES2, KHR

python74

btw: on device EGL/GLES driver stack passing all tests

SGaist

Since you already have the -v option, can you post the failure message ?

python74

Looks like the configure output is not complete, I don't see any failure there.

python74

What You mean by incomplete?

SGaist

In verbose mode, the configure script prints way more lines than what you have here.

Did you re-run configure from a clean state ?

python74

before config i did make clean all

SGaist

You just cleaned the build artefacts not the configuration stuff. You should do out of source builds, that way you can just nuke the build folder if something fails and the source will stay clean.

python74

Thanks. How to do build to another dir?

jsulm

@python74

mkdir build
cd build
PATH_TO_QT_SOURCE/configure ...
make

python74

Thanks for help. But i have another problem. I removed old src directory an was trying to compile qt again. And then problem starts - running configure script and instead make shell trying to use /usr/lib/x86_64-linux-gnu/qt5/bin/qmake wchich btw i removed wit previous QT. Qt5 was installed with qt creator. How to avoid that?

jsulm

@python74 said in eglfs + framebuffer - display issue:

instead make shell trying to use /usr/lib/x86_64-linux-gnu/qt5/bin/qmake

Sorry, I don't understand that: if you try to call make qmake is called or what? Can you please explain better (show the steps you did)?
