Jantje,
I downloaded "twi.h" from Arduino issue #791 Google Code Archive - Long-term storage for Google Code Project Hosting. .
I still didn't manage to compile my code and the error is the same I posted above.
Is there any more step to follow? I really enjoy your Eclipse plugin but since I need to compile Wire library, I don't know what to do...
Has anyone else had this problem?
Thanks.
