Building in WinAvr on WindowsXP

Hi,
I have used your make file and it worked fine.  Now I am trying to add 
additonal code to your project.  I have the lastest version of WinAvr 
4.16.638 installed on a Windows XP system  I'm using a Atmega168p.

I have added all the required files.  I also created a f_osc.h to add the 
f_osc 16000000 to the project to prevent the f_osc errors when building 

I would like to add more features to your base program to monitor a home 
test project. (humidity and pwm fan control) I am a newbie to AVRs and 
programming.  So I was trying to get the your base program to work as is 
before proceeding.  

When I try to rebuild all I get the following warnings and errors.

make: *** [usbtemp.o] Error 1
Build failed with 4 errors and 3 warnings...

What steps will reproduce the problem?
1. Configure program in WinAVR and try to build or rebuild.

Hi Bowen,

sorry to hear this. I don't have a Windows machine, so I can't reproduce your
problem. The warnings are well-known (to me) and can be safely ignored, 
although this
is not good programming style. The errors regarding PB2 are serious, though. 
This
looks to me as if the avr-gcc definitions of the ATMega168p are not loaded.

Lacking any experience with WinAVR, I don't really know how to solve this. I 
noticed,
however, that the register constants defined in "iom168p.h" contains

#define PORTB2 2

so probably the names have changed from the ATMega168 to the ATMega168p. Again, 
I
can't reproduce this, but could you try changing PB2 to PORTB2? So, either you 
need
to patch the source or you change to the ATMega168.

HTH,
-Mathias
