Hello,
I think there might be something going on (or I am doing the same mistake),
after trying to create a recent version of the AVR compiler, I am getting :
$ avr-gcc -v test.c
Using built-in specs.
COLLECT_GCC=avr-gcc

/tmp/ccs8LCB0.s:20: Error: no such instruction: `ldi r25,0'
I am on debian wheezy with the package provided avr-binutils and avr-libc.
The test program is just :
int main () {
return 0;
}
Here the compiler is using "as"(x86) instead of "avr-as" so it cannot
compile the assembler output of the compiler.
so either there is a missing option to the configure script for gcc. Do we
need to provide --program-prefix=avr- configure option ?
Regards
Francois
