How activate OpenGL with QT framework on STM32MP157C-DK2 ?

[ABous.1]

Hello,

I create a custum linux distributuion for specific application. My goal is to use QT framework with OpenGl library trough GPU. To do that I used Buildroot 2019.023.1 and custum linux (V4.19) provided by your github.

What parameters should I activeted to run my QT application with the -plateform elgfs argument ?

I mean what library should I need (mesa or an other one) to run properly my application ?

Hi @ABous.1​ ;

I will ask some expert if we can give some further hints for your context ( buildroot/ 4.19) .

But be aware that ST is delivering and mastering only solution based on Yocto.

Moreover in latest Ecoystem release V2.1 we have delivered some improvement on QT integration side.

See https://wiki.st.com/stm32mpu/wiki/STM32MP15_ecosystem_release_note :

• QT eglfs sample image was improved to reach better performances
• QT wayland sample image was added: more relevant for the OpenSTLinux distribution
  • see How_to_build_and_use_an_SDK_for_QT

Probably the fastest way to get the state-of-the-art of our QT offer.
