Can't make gcc for avr

Can't make gcc for avr

[Russ.Shaw]

Hi all,

I'm using mandrake 7.0 and trying to compile the avr gcc
compiler. I think the 'make' step is trying to assemble
some avr instructions as 386 code. What can i do?

I've downloaded gcc-2.95.2 avr c-compiler sources,
then done:

cd gcc-2.95.2
make

This is some output i get:

(cd intl && make all)
make[2]: Entering directory `/home/russell/tmp/gcc-2.95.2/gcc/intl'
make[2]: Nothing to be done for `all'.
make[2]: Leaving directory `/home/russell/tmp/gcc-2.95.2/gcc/intl'
rm -f tmplibgcc1.a libgcc1.S
cp ./config/avr/libgcc.S libgcc1.S
for name in mulqi3 mulhi3 mulsi3 umodqi3 udivqi3 modqi3 divqi3 umodhi3
          udivhi3 modhi3 divhi3 umodsi3 udivsi3 modsi3 divsi3 prologue
          epilogue __exit; \
do \
  echo ${name}; \
  /home/russell/tmp/gcc-2.95.2/gcc/xgcc -B/home/russell/tmp/gcc-2.95.2/gcc/
          -B/usr/local/avr/bin/ -I/usr/local/avr/include
          -O2  -DCROSS_COMPILE -DIN_GCC
          -g -O2 -I./include  -DDF=SF -Dinhibit_libc -g1  -DIN_LIBGCC2
          -D__GCC_FLOAT_NOT_NEEDED   -I. -I. -I./config -I./../include
          -c -DL${name} libgcc1.S; \
  if [ $? -eq 0 ] ; then true; else exit 1; fi; \
  mv libgcc1.o ${name}.o; \
  avr-ar rc tmplibgcc1.a ${name}.o; \
  rm -f ${name}.o; \
done
mulqi3
make[1]: Leaving directory `/home/russell/tmp/gcc-2.95.2/gcc'



After this point, i get these errors:
