Compiling gcc.3.0.4 for m68k-elf with C++-support

[Lau Sennels <v6421a at gjk dot dk>]

Hello.

I am attempting to compile a linux-m68k-elf crosscompiler based
on gcc-3.0.4 with C/C++-support on Redhat 7.2. I get the following
error when compiling the (final) compiler:

/home/erik/src/build-gcc/gcc/xgcc -B/home/erik/src/build-gcc/gcc/
-B/home/erik/m68k-elf/bin/ -B/home/erik/m68k-elf/lib/ -isystem
/home/erik/m68k-elf/include -c -DHAVE_CONFIG_H -g -O2 -I.

make[1]: Leaving directory
`/home/sennels/src/build-gcc/m68k-elf/libiberty'
make: *** [all-target-libiberty] Error 2

My approoach is this:

PREFIX=/home/erik/src
TARGET=m68k-elf

1) build/install binutils-2.12
2) build/install bootstrap-gcc (3.0.4)
$ ../gcc-3.0.4/configure --target=$TARGET --prefix=$PREFIX \ 
   --without-headers --with-newlib --with-gnu-as --with-gnu-ld \ 
   --with-local-prefix=${PREFIX}/${TARGET} --disable-shared \
   --enable-languages=c,c++
3) build/install newlib-1.10.0
   ../newlib-1.10.0/configure --target=$TARGET --prefix=$PREFIX
4) compile
$ ../gcc-3.0.4/configure --target=$TARGET --prefix=$PREFIX \ 
   --enable-languages=c,c++ --with-local-prefix=${PREFIX}/${TARGET} \ 
   --with-gnu-as --with-gnu-ld

The process fails in 4). It does compile when I turn off c++-support.
Can anyone suggest what I am doing wrong?

Best regards
Lau Sennels
