Errors verifying program, in Wire library - ... 'was not declared in this scope'

Using Arduino Programming Questions

I'm very new to Arduino, so this is probably a simple mistake I've made somewhere - I've looked around for references online to the same set of errors, but haven't found any so far.

When verifying compilation, I'm receiving the following error messages - it doesn't seem to come from within my sketch (at least doesn't reference it), but from the Wire library:

Wire library is referred to from my sketch in two places -

Imports:

#include <SoftwareSerial.h>
#include <SPI.h>
#include <Wire.h>
#include <ITG3200.h>
#include <ADXL345.h>

And setup():

  //join I2C bus
  Wire.begin();

Thanks in advance for any troubleshooting ideas.

I think that the problem is not in the "Wire.h" library but int the "twi.h". Search if you have that library. In my system I have it in the folder 'utility' inside the Wire folder.

When verifying compilation

Using what version of the IDE on what operating system to compile what code? There is so much left out of your post that you can't reasonably expect help.
