Unknown Error while building an Unreal Project on Ubuntu 14.04

I am trying to compile a Game binary in Unreal Engine 4.12. I am also using a 3rd party plugin called UnrealCV.
I get the following error -
Package Results: Error unknown Error.link text

Help would be much appreciated.

Hey Hieronymous18-

Looking at the logs provided, it appears that the UnrealCV file TcpServer.h has a function that is marked as visible to the editor/blueprints but does not have a Category. Specifically, it appears to be referring to the the boolean bIsConnected. If you’re able to open this file, you should be able to add Category = "Name" to it’s UPROPERTY and compile.

Cheers
