Ok, I check /usr/lib and found 2 files related to librocket:
- libp3rocket.so
- libp3rocket.so.1.8
So, the _rocketcore file was missing.
Next, I deleted the 1.8.0 version, and reïnstalled it.
No luck, still can’t find the _rocketcore.so. Maybe if someone wants to upload it, I can just paste it into the folder?
Thanks in advance!
