Some files are still missing in your repo for the Project to be able to compile.
As far as I've checked if the engine is properly configured with OAConsumer and YAJL or NSXML or libXML, it compiles....
VFTwaatStreamingEngine.h:10:38: error: FVTwaatEngineGlobalHeader.h: No such file or directory
I'm having this issue as well. Several files are missing. Maybe they need to be added to the git repo?
Ah! So I'm not the only one. Yeah, pretty sure some files are missing from the repo :(
This file is useless :)
Did you tried to compile and comment this line??
