Is support for Linux 5 scheduled? #16

Closed Pastim closed 5 years ago

Pastim commented 5 years ago

Talpa fails to compile on linux 5.0 (ubuntu 19.04). Is support being planned?

chrishantha commented 5 years ago

I also tried to compile Talpa following instructions at https://community.sophos.com/kb/en-us/13503

But it fails. Build logs at ./talpa/build/talpa-1.24.3/build.log
