x11: cog on VirtualBox Ubuntu 20.04 seg fault core dumped #621
Description
Hi, I'm trying to get cog to run on a Ubuntu VM running 20.04.4 which has graphics llvmpipe and Windowing System X11.
I am seeing this issue with the simple steps: install cog / wpewebkit etc. from Ubuntu with sudo apt install. Run cog with $ cog https://google.com error:
** (cog:1723): WARNING **: 12:02:21.844: Platform setup failed: Could not open Wayland display
** (cog:1723): CRITICAL : 12:02:21.844: WebKitWebViewBackend webkit_web_view_backend_new(wpe_view_backend, GDestroyNotify, gpointer): assertion 'backend' failed
** (cog:1723): ERROR **: 12:02:21.844: Could not instantiate any WPE backend.
Trace/breakpoint trap (core dumped)
So, I run weston to create the display first, and then run cog to get:
$ cog https://google.com
Cog-Message: 12:04:37.124: https://google.com/ Load started.
Cog-Message: 12:04:37.129: https://www.google.com/ Redirected.
Cog-Message: 12:04:37.382: https://www.google.com/ Loading...
Segmentation fault (core dumped)
I have tried building cog with x11 platform with $ COG_MODULEDIR=$PWD/platform ./launcher/cog --platform=x11 https://www.igalia.com and this does launch a window for a moment, but then crashes.
Please, is it possible to run cog on VM running this version of Ubuntu with X11? If so please advise of any settings or setup I need to use etc.
Any info on this is greatly appreciated!
