Thank you,
Some of what you say is new to me. I am unfamilar with ar code for example. I suppose that is handled by avrstudio4 behind the scenes.
However, i thought that avr-gcc would compile c++ code. so it seemed to me that the libraries should be usable with cpu identification from avrstudio4. but this didn't work. the c++ code would not compile.
so i asked questions.
after doing the ar code, i should place those files into my library directory where winvavr can find it. then i should be able to call the functions as before by including the libraries by their new names. $include newname.a.o did i follow you correctly?
Also, where did smiley put those libraries?
