The following errors are thrown by ver 12 on compile. Version 11 does not give any errors when compiling the same code.

I previously posted this in Troubleshooting, but it appears that it may actually be a bug in version 12. http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1224824424

a hack you could try that may work is to add:
#include "wiring.h"

before:
#include "_init.h"

5

Still gives these errors:

\Temp\build16043.tmp\/_init.h: In function 'void ds_init()':

\Temp\build16043.tmp\/_init.h:81: error: 'Serial' was not declared in this scope

In file included from C:\program Files\arduino-0012\hardware\cores\arduino/WProgram.h:4,

What is causing this? Are core libraries that are automatically imported for the sketch file not being imported before the _init.h header?

6

Are core libraries that are automatically imported for the sketch file not being imported before the _init.h header?

I guess so. I wonder if the Arduino parser is getting confused with the '_' in front of those include files.

Anyway, try including HardwareSerial.h

The errors just get more interesting when I added the #include "HardwareSerial.h" :o

I did try taking the _ out of those header names, but the same errors occurred.

Try removing the other includes you added and just have the following:
#include <math.h>
#include <wiring.h>
#undef int
#include "_init.h"
#include "_data.h"

if you still get errors, try adding the following after the #undef int
#undef abs
#undef double
#undef float
#undef round

9

With those includes, the errors are the same as the one before the addition of the #include "HardwareSerial.h"

Thank you for working with me on this.

10

Go back to the verison before my previous post and just
try to add the undef statements.

11

Try adding:

#include "WProgram.h"

to _init.h. Also, I think Zach may have corrected these examples, so you might try looking for a more recent version.

12

mellis: that fixed it. thank you very much. The example code I posted is the most up to date available. Can you tell me why is it that 11 has no problem with that include not being there?

13

The location at which the automatically generated #include "WProgram.h" is inserte in a sketch changed between 0011 and 0012.
