Syntax Error causing boolean / byte to be unknown
02.04.2008 at 02:26:37

I am sure it is some syntax I am doing. Oddly enough, if I change all the booleans to say, longs, it compiles ok.

I removed the logic out of the .cpp and the main file to make my troubleshooting easier.

At this point I am stuck, so any help is appreciated.
This is all in Arduino 11

error:
(more or less saying every byte and boolean definition is an issue)
Code:

To use "boolean" it in a library you must include the file "WConstants.h" into your cpp-file before "tank.h" that is using the datatype. Start the cpp-file with : Code: #include "WConstants.h" #include <Wire.h> #include "tank.h" Eberhard

easy enough! thanks

its true, but if you look at the things that get included with "WConstants.h" (which includes "wiring.h" ) you'll see that almost every arduino-specific function are defined here.

So if you are new to the Arduino, its best to include "WProgram.h" (which in turn includes "WConstants.h") to gain access to functions like digitalWrite(), shiftOut() etc.

I would suggest everybody should at least once have a look at the files
arduino-0011/hardware/cores/arduino/wiring.h WConstants.h WProgram.h
to see whats defined in them.

No argument here. The bigger question is why WProgram.h isn't being included by default during compilation. It certainly wasn't explicitly necessary under 0010.

It's not included in other .cpp, .c, or .h files, under the assumption that if you're using them, you know what you're doing (or aren't afraid to ask for help), and you don't want the Arduino pre-processor messing with your code.

If tank.h is being processed as part of the main .pde, and WProgram.h is included before tank.h, there should be no error. I had not caught the extra .cpp file in my first reading.
