cog not working on hardknott

[gnulux]

Describe the issue Wich branch is working with Yocto Hardknott release ? I built fsl-imx-wayland for imx8mp and i have the folowing error in terminal from Weston.

cog -P fdo https://www.google.com
(cog:1979): Cog-Core-WARNING **: 16:51:34.882: Platform module name 'fdo' is deprecated, please use 'wl' instead.
(cog:1979): Cog-Core-WARNING **: 16:51:34.884: cog_modules_get_preferred: cannot find module 'wl'
(cog:1979): Cog-Core-WARNING **: 16:51:34.884: cog_modules_get_preferred: preferred module 'wl' not supported
(cog:1979): Cog-WARNING **: 16:51:34.884: Cannot create platform: Could not find an usable platform module
wpe: could not load the impl library. Is there any backend installed?: libWPEBackend-default.so: cannot open shared object file: No such file or directory
Aborted

I suppose that cog was compiled with drm instead. it launch something when i run cog -P drm from local console but can't read nothing as drm not supported for Vivante driver . I already build and run cog with Yocto (Zeus) before but with meta-webkit from Dunfelll. Perhaps I need to change branch. Can you help me with this

**Expected behavior**
expect to have cog browser on Weston compositor

**Screenshots**
If applicable, add screenshots to help explain your problem.

**Environment (please complete the following information):**
 - yocto release: harknott
 - hardware targe: IMX8MP / Wayland

[clopez]

This can be related to the environment.

You should start cog from inside a weston terminal, this is the safe-proof method.

But if you are trying to start it from ssh then you have to at least set first the environment variables WAYLAND_DISPLAY and XDG_RUNTIME_DIR to the right values.

Example:

1. Open a terminal inside Weston and get the pid of it

   
   # pidof weston-terminal
   14881

2. Examine the environment variables of that pid

strings /proc/14881/environ

LANG=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin NOTIFY_SOCKET=/run/systemd/notify HOME=/home/weston LOGNAME=weston USER=weston SHELL=/bin/sh INVOCATION_ID=b04467b8cdf149db8c44741a928227fe TERM=linux JOURNAL_STREAM=8:193511 SYSTEMD_EXEC_PID=14862 XDG_SESSION_ID=c7 XDG_RUNTIME_DIR=/run/user/1000 DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus XDG_SESSION_TYPE=wayland XDG_SESSION_CLASS=user XDG_SESSION_DESKTOP=weston XDG_SEAT=seat0 XDG_VTNR=7 WESTON_CONFIG_FILE=/etc/xdg/weston/weston.ini WAYLAND_DISPLAY=wayland-1

3. Export the relevant ones on the ssh session

export WAYLAND_DISPLAY=wayland-1

export XDG_RUNTIME_DIR=/run/user/1000

4. Finally execute cog

cog -P fdo https://google.it

(cog:15036): Cog-Core-WARNING **: 03:27:59.678: Platform module name 'fdo' is deprecated, please use 'wl' instead.

(cog:15036): GLib-GIO-WARNING **: 03:27:59.836: Your application does not implement g_application_activate() and has no handlers connected to the 'activate' signal. It should do one of these. Cog-Core-Message: 03:28:00.750: https://google.it/ Load started. Cog-Core-Message: 03:28:00.833: https://www.google.it/ Redirected. Cog-Core-Message: 03:28:01.233: https://www.google.it/ Loading... Cog-Core-Message: 03:28:02.548: https://www.google.it/ Loaded successfully.

It works to me now, but it was giving the error you get before exporting the environment variables

[clopez]

Can you try exporting this environment variable :

export G_MESSAGES_DEBUG=all

... and run cog again (inside the weston environment) ?

It will print lot of debug messages, paste them here.

EDIT: if you can paste here also the output of this command:

# ls -l /dev/dri

And also the output of the command waylandeglinfo (from inside a weston environment). The recipe to build that command is inside this layer, you can build it with bitbake or add it to your image in local.conf

This is what I get on a RPi3 with the VC4 (open source) drivers: http://sprunge.us/1fv1r9

I have only this with G_MESSAGES_DEBUG=all set .

[clopez]

What do you have inside the directory /usr/lib/cog/modules ? Do you have a file named libcogplatform-wl.so ?

[gnulux]

No only libcogplatform-drm.so

root@lec-imx8mp:/usr/lib/cog/modules# ls
libcogplatform-drm.so
root@lec-imx8mp:/usr/lib/cog/modules# 

[clopez]

Ok.. there is the problem. You are missing libcogplatform-wl.so in that directory

Can you try to rebuild after setting this in your local.conf:

PACKAGECONFIG_pn-cog = "wl"

(so use wl instead of fdo)

Questions:

1. Do you have a libcogplatform-wl.so after that in /usr/lib/cog/modules ?
2. Does that make any difference? Does cog now work?

[gnulux]

Ok , I rebuilt only cog and installed the deb package and it works now . Thanks a lot.

[clopez]

Great! :+1: Happy to know that it works! :tada:
