6 years ago Can you get a debug log of pidgin loading the plugins?
To do this, open Help->Debug Window, then leave that window open and open Tools->Plugins. Close the plugins window then copy-paste the output of the debug window.

6 years ago @EionRobb Thanks for the troubleshooting details, had no idea that debug window existed. Looks like this is the cause. Not sure what the fix is though.
(16:45:46) plugins: probing /home/user/.purple/plugins/lurch.so
(16:45:46) plugins: /home/user/.purple/plugins/lurch.so is not loadable: failed to map segment from shared objectI've never seen "failed to map segment from shared object" as an error when loading any plugin in Pidgin before. A quick googling says something to do with /tmp not being exec (sudo mount /tmp -o remount,exec to fix, not sure what the implications of that are), something to do with the .so not being marked as executable (chmod +x ~/.purple/plugins/lurch.so) or something to do with selinux not being permissive (might need to do a system-wide install, rather than just a user install)

6 years ago I saw that when I Google'd too but I didn't think it was relevant. I found the cause though. The is due to the https://packages.debian.org/stretch/apparmor-profiles-extra package which contains /etc/apparmor.d/usr.bin.pidgin
When setting this to enforce mode like this.
sudo aa-enforce /usr/bin/pidginIt messes with something and doesn't allow it to execute lurch.so maybe?
When setting it to complain mode the issue goes away and the plugin loads.
sudo aa-complain /usr/bin/pidginThis is what the AppArmor config for Pidgin looks like.
user@personal:~$ cat /etc/apparmor.d/usr.bin.pidgin
# vim:syntax=apparmor
#include <tunables/global>

}Ah yep, its a similar answer to the "selinux enforcing" answer. The apparmour profile you've provided doesn't give you permissions to load plugins that were installed into @{HOME}/.purple/plugins. Either install it into the system-wide /usr/lib/purple-2/ folder or add @{HOME}/.purple/plugins/*.so rm, to the apparmour profile.

6 years ago Thanks for the assistance. I'll close this out as it's not an issue with your plugin. :)

1 year ago I have this problem too. In Debug Window:
(21:40:55) plugins: /usr/lib64/purple-2/lurch.so is not loadable: undefined symbol: jabber_pep_namespace_only_when_pep_enabled_cb
Hi there. I built the plugin using the guide. I'm running on Debian 9 (Stretch). When I open Pidgin I don't see the plugin in the list at all. I'm wondering if Pidgin doesn't read the .so from the directory it was placed in. Pasting build logs below.
Running Pidgin 2.12.0-1
