[meta-freescale] Using Qt EGLFS without wayland DISTRO_FEATURES on i.MX8

[Karim ATIKI]

Hi Diego,

No, this is not a shortcoming, afaik.
Current iMX8 config does not support, and will not support eglfs.
Wayland /XWayland is the alternative to use.

And even if your DISTRO_FEATURES contains wayland or xwayland, eglfs in PACKAGECONFIG will raise an error during the build.

However, OpenGL ES 1,2 and 3 is still supported by Qt on IMX8.


Karim.

Objet : [meta-freescale] Using Qt EGLFS without wayland DISTRO_FEATURES on i.MX8

Hi,

As far as I understand it is currently impossible to build qtbase with "eglfs" in PACKAGECONFIG without also having "wayland" in DISTRO_FEATURES in a build for an i.MX8. Is this correct?


This is my reasoning:
1) the currently available i.MX8 SOCs all have "imxgpu3d":
https://github.com/Freescale/meta-freescale/blob/master/conf/machine/include/imx-base.inc#L79
2) this means that qtbase PACKAGECONFIG_GL will be "gles2":
https://github.com/Freescale/meta-freescale/blob/master/dynamic-layers/qt5-layer/recipes-qt/qt5/qtbase_%25.bbappend#L22
3) so imx-gpu-viv will be required to provide "virtual/libgles2". imx-gpu-viv then requires "wayland" as a DISTRO_FEATURE
https://github.com/Freescale/meta-freescale/blob/master/recipes-graphics/imx-gpu-viv/imx-gpu-viv-6.inc#L56

Is this a shortcoming of how imx-gpu-viv libraries are provided by NXP?

Thank you,
Diego
