Hi,

Can I see verbose output from arduino and from visual micro please.

This will show us which tool chains are being found, which hardware is being compiled and which files.

nb: If you have .ino code that is passing a user type created in an .ino then you will need to add a prototype between creation of the type and the use of it (might or might not apply to your code).

Thanks

The Visual Micro result shows your code uses a couple of libraries

The Arduino result shows your code does not use any libraries.

You need to run this test using the same code or are the RF24-master and SPI libs not supposed to be found?

The arduino ide outputs a program size of 444 bytes

The only way that can happen is if there isn't any code.

I am having a problem seeing what problem you are reporting. You can see below extracts from the outputs you posted. Using identical tools and libraries resulting in identical output file and memory use size.

Is it possible your original report was confused by the fact you were comping an empty project in the Arduino IDE or am I missing the point?

Thanks

Arduino Uno

You're not going to believe this one! 

The program I am working on at the moment (in VS/VM) has the function call
setWorking(nodeAddresses[1]);

It builds and uploads to the Arduino PCB with no problem.  My problem is that there is no function setWorking()  either forward declared or implemented in the program.

To make matters worse, all was functioning apparently normally with this code

	if (debug)
	{
		Serial.print("Handshake message starts as ");
		Serial.println(handshakeData);
		Serial.println();
	}  // end if 

without the booloan variable debug  being declared.

The build outputs are too big to include so I have attached them.

Quite the contrary!

Nothing compiles correctly!

How can an IDE build and upload  a function that hasn't yet been written?
