Using 1.0-rc1, WConstants.h / wiring.h missing #682

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
On the Windows version of Arduino 1.0-rc1, any libraries such as EL_Escudo, 
that references WConstants.h (which references wiring.h) will fail to compile.

Both WConstants.h and wiring.h are not found under 
"hardware\arduino\cores\arduino" in Arduino 1.0-rc1.

I was able to get libraries to work by including "wiring.c" directly. But, I am 
not sure of the implications of that.

Here is an example library referencing WConstants.h (line 13):

https://github.com/ryowens84/EL-Escudo/blob/master/EL_Escudo.cpp

Changing line 13 to the following allows the sketch to compile:
#include "wiring.c"

Both WConstants.h and wiring.h are also not included in the Mac version of 
Arduino 1.0-rc2.

Furthermore, the example sketch from OneWire library, which references to 
WConstants.h, fails also to  compile.
However, the above solution with including a reference to "wiring" does not 
help. Moreover, old WConstants.h and wiring.h files from Arduino 0022 also do 
not allow to compile the sketch.

Under 1.0 and later, you're meant to use Arduino.h rather than WConstants.h. 
This is known to break compatibility with old libraries.

Yeah, these were removed intentionally.  You can use Arduino.h instead.

I got this to work... Any instance of "WConstants.h" or "wiring.h" needs to be 
replaced with "Arduino.h".

Thanks.

I'm using LCD4884 library in one of my projects, and I had this issue.
At first, the compiling error was that "WConstants.h" didn't exist. I replaced 
"WConstants.h" with "Arduino.h" and now I have about 15-20 compiling errors, 
mostly pertaining to conflicting lines.
Any ideas?
Thanks!
