xcb as backend

[Tom Deblauwe]

Hello,

I'm using a buildroot build with the enlightenment libraries, and I have compiled libevas with the "xcb" backend support. Now when starting "enlightenment_start", I get the error that it can not find support for software X11 rendering. However, I compiled in the xcb backend, but not the xlib backend. I also compiled in the opengl xcb backend, see output below.

Is there maybe a way to force enlightenment to use the xcb backend?

I know it should work because I can run Qt5 apps which use xcb: I can start them with the "-platform xcb" commandline flag and they work. I thought maybe I can do something similar with "enlightenment_start" ?

Any hints what I could try?

Thanks!
Best regards
Tom,
