[Question] Z-order management in Wayland

[Manuel Bachmann]

Yan,

"gl" comes from the mesa package, but has been disabled in the pure wayland
profile ("libGL.so" pulls "libX11.so"). My guess is that your gbs'
build.conf is not correct or up-to-date, as "gl" only appears if the "%with
x" macro is defined, while it is not in recent config files.  So you likely
have the good repo but a bad config file.

As this discussion is more Tizen-specific than Wayland-specific, would you
mind that we go further with private email, or -better- in the Tizen-IVI
maling list (ivi at lists.tizen.org) ?

Regards,
