DPRG mailing list archives: [DPRG] Trouble getting WinAVR20070122 working

Fri Mar 16 09:23:20 CDT 2007

I am not an expert on makefiles, but you have a problem in the makefile.
If you did not modify the makefile, change the name of your program file
to main.c.

There is a way to program C inside AVR studio, that takes care of it for
you.
