undefined reference to 'vtable for Channel'

[brunapearson]

Error found when compiling. The error msg points out to serialFork.cpp:180 and serialFork.cpp:200

I ran into this same issue. The solution was to go into serialFork.cpp, class Channel and set each of the virtual methods =0, as below:
virtual uint8_t _serial_available()=0;
virtual uint8_t _serial_read()=0;
virtual uint8_t _serial_write(const uint8_t *data, size_t length)=0;
virtual void _serial_flush()=0;

these occur on lines 79-82.

This is already in the other two branches, but not merged to master yet.

Thanks for letting me know about it :)
