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

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"

[Reply #4 on:]

Still gives these errors:

Code:

\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?

[Reply #5 on:]

> 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

[Reply #6 on:]

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

Code:

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

[Reply #7 on:]

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

[Reply #8 on:]

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.

[Reply #9 on:]

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

[Reply #10 on:]

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.

[Reply #11 on:]

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?

[Reply #12 on:]

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