Hey Ododo,
The master branch is constantly updated with largely-untested changes, making it unstable at best. The Building On Linux wiki page recommends using the 4.7 Release branch or the 3dluvr 4.7-linux branch (specialized for linux, naturally). If there’s a feature in the master branch you specifically need, it might be easier to build 4.7 and then just implement the file changes that add that feature (rather than pulling down the entirety of the master branch).
Additionally, while I’m happy to help with any further issues you may have, the guys in AnswerHub’s Linux section are extremely knowledgeable and can probably offer more specialized advice than I can.
Regards,
Jonathan
