[agl-discussions] Issue : Qt5 examples with wayland-egl plugin deos not work by 'EGL not available'

[YOSHIYUKI ITO]

Hi Tanikawa-san and Steve-san,

  I've heard that there are some Symbol name collision exist between Wayland and Qt.
An Cogent guy and some other person made a trial patches to solve this issue.

  May I ask you to try with attached patch?
Original author of the patch said that it's too nasty, but I expect it solve this issue.

Regards,
Yoshiyuki Ito.

Hi Steve, Ito-san, or anyone who has any idea or help,

In order to determine the cause of this issue, I've built GDP and run weston with desktop-shell.so, then I found that there is the same issue on GDP too.

GDP also needs LD_PRELOAD=/usr/lib/libEGL.so to launch Qt5 apps with wayland-egl.so plugin which is required by all examples of qt3d, and transparency is corrupted. (attach screen shot running /usr/share/qt5/examples/qt3d/cubehouse, cylinder)

There might be something wrong around QtWayland or PVR middle/drivers.
OR it might be just because my porter board would be broken, ... I'm not sure.

Anyway, I will post the patch for Qt5 integration to gerrit for now, so that more people would be able to work for it.

Regards,
Tadao Tanikawa
