Let me apologize for the long post upfront...
Perhaps someone can help with a WinAVR problem. I just upgraded to
WinAVR20070122 (great right?) well... using my previously running code
and the new makefile template (with the appropriate source name,
device, etc. changes) I can't get it to work correctly.
+++++FIRST+++++
I get the following message after I click MakeAll (with either a newly
generated project or after a MakeClean):
> "make.exe" all
-------- begin --------

make.exe: *** No rule to make target `SRbot.o', needed by `SRbot.elf'.
Stop.
> Process Exit Code: 2
+++++NEXT+++++
If I put an old version of SRbot2.o in the project directory I get this
response from WinAVR20070122:
> "make.exe" all

+++++THEN+++++
If I put old versions of these 2 files: (SRbot2.o and SRbot2.elf) in
the project directory then I get what appears to be working...so long
as I don't do a MakeClean. HOWEVER, the 2 files mentioned above are
not updated. Also note that avr-gcc apparently doesn't recognize the
device (from MCU = atmega168 line in makefile I assume.)

+++++FINALLY+++++
I wonder if there is a subtle error in the new makefile. It appears
that the make.exe (makefile) is doing things out of order. Why for
example is it Linking SRbot2.elf on a MakeAll? There appears to be a
rule for making SRbot2.o in the new makefile, but I'm no expert on gnu
makefiles. Any ideas how to get WinAVR20070122 working?
Thanks for any help,
James Harris
