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

[Nick Brent]

Yep. Your right. The command

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

give me the error, but the command

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

compiles just fine. Thanks for the link to the GCC manual. I've been using
'GCC the Complete Reference' by Arthur Griffith, and I didn't see anything
about order in the syntax. Thanks for the help.

                                                    -Nick
