When I try to run QT4 (embedded) on my i.MX6 platforms, they

Has anyone else tried this on i.MX6 (and got it to work)?


Mario (added in Cc) has got same error in one of our customers BSP, he is investigating the issue.

Mario, it seems the error is because it is using the X11 backend. So please rebuild using:

DISTRO_FEATURES_remove = "x11 wayland"

and retest.
Sadly, that fails big time :-(

ERROR: Nothing PROVIDES 'virtual/libx11' (but /home/local/poky-multi/meta/recipes-multimedia/gstreamer/gst-plugins-base_0.10.36.bb DEPENDS on or otherwise requires it)
ERROR: libx11-diet PROVIDES virtual/libx11 but was skipped: missing required distro feature ['x11'] (not in DISTRO_FEATURES)

ERROR: nativesdk-libx11 PROVIDES virtual/libx11 but was skipped: missing required distro feature ['x11'] (not in DISTRO_FEATURES)
NOTE: Runtime target 'qwt-e' is unbuildable, removing...

ERROR: Required build target 'my-qte-image' has no buildable providers.
Missing or unbuildable dependency chain was: ['my-qte-image', 'packagegroup-core-qt4e', 'qwt-e', 'qt4-embedded', 'gst-plugins-base', 'virtual/libx11']

I'm not sure why this is the case since the gst-plugins-base recipe
uses PKGCONFIG to control this:
PACKAGECONFIG[x11] = "--enable-x --enable-xvideo,--disable-x --disable-xvideo,virtual/libx11 libxv libsm libice"
I've worked past this error (in my distribution layers) and am building
the QTE image from scratch. This takes quite a while - I'll report what
I find when it's complete.
This now works. I can't tell if it's using the Vivante - the display is
pretty slow...

Also, I get continuous errors/warnings running the demo:
QWSLock::down(): Invalid argument
QWSLock::up(): Invalid argument
QWSLock::up(): Invalid argument
QWSLock::down(): Invalid argument
...

Any ideas about this?

Thanks
