Hello Community!


So far I have being able to "bake" a build using Yocto dora and use the Vivante examples .

The image that I built was qte-in-use-image and I append the vivante examples. Everything seems to work even though I had to disable X11 manually on the local.conf because it seems like the vivante library can be used for X11 or with framebuffer but not with both enabled.

DISTRO_FEATURES_remove = "x11 wayland"

See this post for more info:Google Groups

I am using the sabre lite board from boundary devices.

in the qte-in-use-image there are some QT examples. Unfortunately the ones for OpenGL didn't work .

When I try to run the helloOpenGL example on /usr/bin/qtopia/examples/opengl/hellogl_es2 I get the following message:

(I run it by giving it the -qws option)

Unable to load library icui18n "Cannot load library icui18n: (icui18n: cannot open shared object file: No such file or directory)"

pwm_config: pwm freq = 32786, clk_select=2 clock_rate=22000000

pwm_config: pwm freq = 20000, clk_select=2 clock_rate=22000000

And I see the QT widget with menus and everything but the middle of the screen is pitch black. The same happens with the texture example. I see the widget, but there where the textures should come I can only see black squares.

Do I need to cross-compile them with a special option or how does that work? I would appreciate any hint.

Does anyone have succedded running the hellogl_es2 example for the imx6 on dora?
