OpenGL functions declaration not found while building a project using Qt5 GUI

[AlexSavo 0]

Hi TinkerBoard team and community,

I am truing to build a project with Qt5 GUI on TinkerBoard according to this instructions.

I am having bunch of errors like this: 

In file included from /usr/include/arm-linux-gnueabihf/qt5/QtGui/QOpenGLFunctions:1:0,
                 from /home/linaro/Src/OpenHantek6022/openhantek/src/glscope.h:9,

     ::glBlendFunc(sfactor, dfactor);

I have found a similar problem reported in a couple of years ago.
Is manual building/installing libmali still the solution for the problem?

hello @AlexSavo

please use the latest image as it's Debian 10, it should solve the problem: https://tinker-board.asus.com/download-list.html?product=tinker-board-2s

Hi;

I tried to use new Debian10 image and result still same.  All mali drivers are listed as truncated. Also, i tried to install mali drivers as declared as in Rockchip github repository, installed successfully but no hope about problem. I was so excited to use ThinkerBoard2 but no chance. If you have any other suggestion, i want to try.

hello @dlphmn,

what image are you using? if you download the official release of debian 10 image from our site it should have solved the issue

Hi;

I did all my test by last official release (as you mentioned) and this problem occured with that. No chance with mali drivers, so we cannot use Qt (C++) for running anything. Even I choose LibGLES as documented, application crushed after start up.
