fbGetDisplay with Yocto build

BrianEdmond — Tue, 03 Sep 2013 18:11:40 GMT

Hi,

I have built a yocto image for a Nitrogen6X board and would like to run an OpenGL ES 2.0 application without X11. I have built an image which does not have X11 but can not figure out how to configure EGL. In previous images, like the boundary devices stock image, I could use fbGetDisplay() and the like in order to connect a framebuffer index which could then be used as the NativeDisplay for EGL. However I can not seem to find a library with the fb* symbols in the yocto build. I was wondering is anyone has used OpenGL ES 2.0 with fbdev and yocto?

Thanks,

Brian

I'm in the process of figuring out how to do this as well.

Have you found a solution?

Hopefully I can make some headway on this sometime this week.

You must change the distro features to accomplish this.

Add:

DISTRO_FEATURES_remove = "wayland x11"

To your local.conf file. This is for playing with it, for products it is advisable to make a custom distribution for it.

I copied one of the files at Index of /buildsources/g/gpu-viv-bin-mx6q and manually copied the fb libraries to /usr/lib. The precise files to copy and links to make depend on the version you use.

I now have both OpenGL ES 2.0 and h264 decoding running on fb.

I thought that only the thread creator could do that.
