Re: [avr-gcc-list] Compiler linking error

[Nick Brent]

Hmm. That seemed to do something. I ran avr-ar with the -s option. I think
took out the 'LDFLAGS += libtest2.a' line that I mentioned earlier, and it
compiled just fine with make. I then ran a 'make clean' and tried to compile
with the command:

    avr-gcc -mmcu=atmega128 -lmyrobot test2.c

and I got the same error message as before. btw, I made sure libmyrobot.a is
in the avr/lib/ directory. I've gotten to the point where it works now, but
what I'd like to do is just give someone a copy of the library, tell them to
stick it and the corresponding headers in certain directories, and then just
call them like they would any other header file. And I'm not quite to that
point. Any suggestions?
