Strange Compile Errors

I am experiencing three strange compile errors:

error: 'MicroDebug' was not declared in this scope @ line 64
error: 'MicroDebug' was not declared in this scope @ line 78
error: '_VM_AUTO_REPORT_LAST_MS_' was not declared in this scope @ line 78

Line 65 is "void setup() {"
and line 78 is "void loop() {"

I have attached the entire code base. The verbose BuildOutput is in the root folder.

Hi Bob,

Please zip the temp build folder so I can see what is being compiled.

Thanks

I could not find where the default temp folder is located so I created a folder in my Arduino root, but when I compiled, noting was in that folder.

How do I reset the temp folder to it's default and where is that?

You can switch on "vMicro>Compiler>Show build folder" but it will also be displayed in the Verbose output

I saw that http://www.visualmicro.com/forums/YaBB.pl?num=1467306804 was having the same problem so I added int dummy; at the top of my file and now am getting different errors.

The temp build folder is over 500K, so I cannot submit it through this interface. Any alternatives?

The problem is that you have added a copy of the library source code to your project.

Delete the following from your project and from the project folder

HMC5883L.cpp
HMC5883L.h
twi.cpp
twi.h
Wire.cpp
Wire.h

Looks good except that you need to use chevrons to include files that are not in your project
#include <lib.h>

not

#include "Wire.h"
#include "twi.h"
#include "HMC5883L.h""

Right you are... but I am still stumped. Why could it not find these files int their libraries before? Could it have been the conditional compiles and #ifdef statements at the top of the compass.ino file?

Yes the insert point for the standard headers (debug and arduino.h) will have been inside some code that is currently disabled
