Your title for this bug is misleading as it seems you're building a
cross for a newlib bare metal target, not i686-pc-linux-gnu.  That's
just the host, and is irrelevant to the issue.

There is currently a known problem with the libstdc++ configury and bare
metal newlib targets.  You can fix it either by providing BSP files
(crt*.o, linker script, etc) for your board so that test programs can be
linked, or you can disable the AC_LIBTOOL_DLOPEN check in
libstc++-v3/configure.ac for newlib targets, as in
<http://gcc.gnu.org/ml/gcc/2007-11/msg00790.html>.  For a summary of the
history of this issue:

Brian,
first, thank you very much for such a quick response.

Actually, this target is  i[3456789]86-*-elf) /*gcc-4.3.0/configure */

sincerely,
yakov

------- Comment #3 from pinskia at gcc dot gnu dot org  2008-03-30 20:19 -------
Using a sysroot or setting --prefix for both the newlib build and the GCC build
is the easiest way of getting a cross build to work.

Anyways here are the options I use to build a cross build for spu:
stage1
  binutils: ../src/configure --target=spu-elf --prefix=${HOME}/gcc-spu
  gcc: --prefix=${HOME}/gcc-spu --enable-languages=c --with-mpfr=/usr/local
--with-newlib --without-headers --target=spu-elf
  newlib: ../src/configure --target=spu-elf --prefix=${HOME}/gcc-spu
stage2
  gcc: --prefix=${HOME}/gcc-spu --enable-languages=c,obj-c++
--with-mpfr=/usr/local --with-newlib --target=spu-elf --with-headers


This works without changing any source or headers too.

Thanks,
Andrew Pinski
