unable to configure for m68k

unable to configure for m68k

[Bart Locanthi]

hi, i'm trying to build a cross-compiler on linux to target m68000, and 
i think the coldfire variant.

however, when i try to configure/make it, i get a message about the 
assembler not knowing about the 68020.

i've tried telling configure to only target the 68000 but that option 
doesn't work for m68k.

here's one of many things i've tried:

% ./configure --prefix=/usr/local/68k --target=m68k-none-elf 
--with-gnu-as --with-gnu-ld
% make
...
/usr/local/src/gcc-3.4.0/gcc/xgcc -B/usr/local/src/gcc-3.4.0/gcc/ 
-B/usr/local/68k/m68k-none-elf/bin/ -B/usr/local/68k/m68k-none-elf/lib/ 
-isystem /usr/local/68k/m68k-none-elf/include -isystem 
/usr/local/68k/m68k-none-elf/sys-include -O2 -DIN_GCC -DCROSS_COMPILE   
-W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes

-I./../include   -g0 -finhibit-size-directive -fno-inline-functions 
-fno-exceptions -fno-zero-initialized-in-bss -fno-unit-at-a-time  \
  -Dinhibit_libc -c ./crtstuff.c -DCRT_BEGIN \
  -o crtbegin.o

make[1]: *** [crtbegin.o] Error 1
make[1]: Leaving directory `/usr/local/src/gcc-3.4.0/gcc'
make: *** [all-gcc] Error 2

suggestions welcome.

You have to build the cross-assembler, in the binutils package, first.
Use the same --prefix.  There is a crossgcc FAQ around somewhere.

cool, thanks.

sigh, unfortunately it looks like c++, java, and objc are unsupported on 
m68k. what's the world coming to when you can't target a, er, umm, 24 
year old architecture?!
