CEF+OZONE+CHROMIUM+Threads using wrong paths?

Postby ildefonso » Fri Aug 05, 2016 11:47 am

I am trying to build CEF with ozone + libcaca to get something similar to this:
but with cefsimple instead content shell.

I studied this old port:https://github.com/kuscsik/chromiumembedded/tree/aura
and I made similar changes, (removing X11 dependecies and using Aura for window creation) and it builds,

however when I run it, I start to get these types of errors:
Check failed: CEF_CURRENTLY_ON(content::BrowserThread::IO).

which makes me think a thread is calling a function/code it should NOT be calling.
and if I remove the check it fails later because a pointer (which I don't remember) should not be zero, which means the state is not valid.

[*]Some ideas why this could be happening ? a thread executing the wrong code?
[*]any advise on porting CEF with Ozone support? (aka. what I should be aware or how to do it? :) )

I am using ubuntu 14.04 (3.19.0-65)
