Description jwack 2021-05-20 18:15:47 UTC

Builroot for raspberry pi4 32bit with x11 support generates an mistake.
"Package buildroot-20210520.tar.bz2"
An error occurs when xstart is called. The error returns the fbturbo_drv.so.
Comment from Xorg.0.log:
Failed to load /usr/lib/xorg/modules/drivers/fbturbo_drv.so: /usr/lib/xorg/modules/drivers/fbturbo_drv.so: undefined symbol: fbdevHWSave

I think we need a update from the xf86-video-fbturbo library.

(In reply to jwack from comment #0)

fbdevHWSave() is defined here [1], so this looks more like a module loading order problem, see e.g. [2] for similar example...

If not please provide a minimal (but complete) defconfig against plain buildroot version to reproduce the problem...

Comment 2 Peter Seiderer 2021-06-02 20:21:42 UTC

Same/similar failure was reported on the buildroot mailing list
'[Buildroot] [RPi4] Enable GTK3 on Buildroot' (see [1]) providing
an buildroot config file to reproduce the failure.

Should be fixed with suggested buildroot patch, see [2].

This was fixed a long time ago in https://git.buildroot.org/buildroot/commit/package/x11r7/xdriver_xf86-video-fbturbo?id=9dc2b4a4eee557d3d9e7df31e9d2e96f364a2f03. Thanks Peter for providing the fix!
