Summary:                    Building toolchains fails with libstdc++-v3 enabled
Description: 
hi there, i am trying to compile a toolchain for mips32, i can compile just
fine but when i enable c++ in configuration make fails with apparently no
reason.

this is what i get:

make[4]: Leaving directory
`/home/bracco/buildroot/toolchain_build_mips_nofpu/gcc-3.4.2-final/mips-linux-uclibc/libstdc++-v3/src'
make[3]: *** [install-am] Error 2
make[3]: Leaving directory
`/home/bracco/buildroot/toolchain_build_mips_nofpu/gcc-3.4.2-final/mips-linux-uclibc/libstdc++-v3/src'
make[2]: *** [install-recursive] Error 1
make[2]: Leaving directory
`/home/bracco/buildroot/toolchain_build_mips_nofpu/gcc-3.4.2-final/mips-linux-uclibc/libstdc++-v3'
make[1]: *** [install-target-libstdc++-v3] Error 2
make[1]: Leaving directory
`/home/bracco/buildroot/toolchain_build_mips_nofpu/gcc-3.4.2-final'
make: ***
[/home/bracco/buildroot/toolchain_build_mips_nofpu/gcc-3.4.2-final/.installed]
Error 2

i think it is just the compile of libstdc++ that fails because some lines
before there's this:

make[4]: Nothing to be done for `install-data-am'.
 /bin/sh ../libtool --mode=install /usr/bin/install -c  libstdc++.la
/home/bracco/buildroot/build_mips_nofpu/staging_dir/mips-linux-uclibc/lib/libstdc++.la
mips-linux-uclibc-ar: .libs/*.o: Nessun file o directory
make[4]: *** [install-exec-local] Error 1

how can i solve that? it is  veeeeeeeery annoying, i spent hours on it,
searched with google and found severeal other libstdc++ issues but none of
the solutions seems to be working for me

forgot to say i'm compiling gcc 3.4.2 and that "Nessun file o directory"
means no "file or directory"

I've seen this too (with gcc-3.4.6), and I think it is caused
by not setting BR2_GCC_SHARED_LIBGCC.

However, it seems that removing the offending .libs/ part
from toolchain/gcc/3.4.x/300-libstdc++-pic.patch
makes it build with either BR2_GCC_SHARED_LIBGCC setting.

...or maybe not:
It seems libtool builds -fPIC versions of the objects
in .libs/, and versions without -fPIC in ., which
are the same for mips-linux (because -fPIC is implied),
but maybe not for other platforms.

libtool doesn't build the -fPIC versions when
BR2_GCC_SHARED_LIBGCC is unset.

Can somebody attach a working patch, please?

Works for me with the fixes i just installed (revision 17099) for gcc-4.2
on i386. Please try 4.2 and report back.
