I'm using gcc-3.2.1, avr-libc-20020203 and binutils-2.12 under linux.
I also tried gcc-3.0.1, gcc-3.0.3 and binutils 2.11.
------------------------
I compile like this:
$ avr-gcc -c test.c
$ avr-ld test.o -o testing -mavr23xx
test.o: In function `main':
test.o(.text+0x3a):undefined reference to `__divmodqi4'
but, if I replace the line a = a / 10; by a = a * 10; like here :
int main()
{
int a = 100;
a = a * 100; // instead of a = a / 10;
test(a);
}
I can compile successfully...
thanks.
