"andi" requires an immediate operand. So it takes the "r24" that is passed by the compiler as an immediate rather than a register. The value of "r24" is not known to the assembler by that time, thus the assembler marks the symbol as "global undefined" in the object file. The linker then eventually complains because it cannot resolve that symbol ... My guess is you'd like to use "and" rather than "andi". ;-) -- cheers, J"org .-.-. --... ...-- -.. .
