I tried to upload code to the Arduino Mega ADK but always come out a warning "error compiling". Is there something wrong with the code? How do I fix this?

the code :

Code:

#include <inttypes.h>
#include <avr/pgmspace.h>

//#include <Spi.h>
#include <Max3421e.h>
#include <Max3421e_constants.h>

#include <Usb.h>

#include <ptp.h>
#include <canoneos.h>

error message :

Code:

core.a(main.cpp.o): In function `main':
D:\arduino-1.0.1\hardware\arduino\cores\arduino/main.cpp:5: undefined reference to `setup'
D:\arduino-1.0.1\hardware\arduino\cores\arduino/main.cpp:15: undefined reference to `loop'

Thanks any help would be great

[Reply #1 on:]

Not to sure yet. Add the function prototypes ( for loop and setup ) your self above all the classes.

Even try placing them above all includes and defines.

[Reply #2 on:]

Do you use the newest Arduino 1.0.3 ?
The example is old.

For a sketch the "#include <inttypes.h>" and "#include <avr/pgmspace.h>" are not needed I think. I'm not sure about a library.

This line causes an error :

Code:

class CamStateHandlers : PTPStateHandlers

Can you try to remove the ": PTPStateHandlers" and see what error you get ?

Try turning on verbose output on compilation - it may give you more errors, like missing header files

[Reply #4 on:]

You have setup() and loop() as functions in the class body.

You REALLY need to learn how to do classes properly. You should have at least three files -  a header file that defines the class, a source file that implements the class, and a sketch that uses the class.
