AM625: Getting eglfs working for Qt6

Hello,

Could you share what type of issues you are observing? In general, we take the meta-qt5 layer and add the following changes on top: 
https://git.ti.com/cgit/arago-project/meta-arago/tree/meta-arago-distro/recipes-qt/qt5?h=kirkstone

-> https://git.ti.com/cgit/arago-project/meta-arago/tree/meta-arago-distro/recipes-qt/qt5/qtbase-conf_1.0.bb?h=kirkstone
-> https://git.ti.com/cgit/arago-project/meta-arago/tree/meta-arago-distro/recipes-qt/qt5/qtbase_%25.bbappend?h=kirkstone

What I have looks very similar to meta-arago. 

If I add the following line I get a compiler error

EXTRA_OECMAKE += "-DQT_FEATURE_egl=ON -D_FEATURE_opengl=ON"

and without that fix the configuration check claims that egl is not available despite it passing the check higher up.

Hello,

What base image are you using? Also, do you see similar issues with Qt5? Based on my internal discussion with our developers, we have not done Qt6 migration so we are not sure if there is anything strange happening in the qt6 layer.

We are using core-image as our base. We want to use Qt 6.5.x as this is the current lts and we our making a major overhaul of our current hardware and software platform, which is something we cant do to often, so we want to be on as late a version as possible. I will do a test later today using meta-qt5 and see if things are similar.

Sounds good and let me know if similar issues are observed with meta-qt5.

meta-qt5 works fine. It seems that is is an issue when building the native part of qt6 where it is trying to compile with eglfs. in qt6 the have combined the qtbase and qtbase_native into one and this is causing an issue for me

Hello,

Thanks for the update. Unfortunately, we have not migrated to qt6 yet because of the lack of community support. We are still actively monitoring the community's stand on supporting Qt6 and if they plan to add meta-qt6 support. I would recommend you to check with the Qt folks because I know they have Qt6 running on our AM62 boards.

Krunal
