[maemo-developers] Scratchbox cs2007q3-glibc2.5-arm7 toolchain support?

[From: Ben Martin]

Hi,
  After my tinkering with trying to get a more recent ld I realized that
I needed to install a scratchbox package or patch an existing one with
ld features to get what I wanted. Having an updated binutils inside
scratchbox was all fine and dandy for compiling using qemu to run the
ARM ld binary but this doesn't scale to large projects (segvs, pain
etc).

  I notice that there is
scratchbox-toolchain-cs2007q3-glibc2.5-arm7_1.0.7-3_i386.deb
released here:
http://scratchbox.org/download/files/sbox-releases/stable/deb/

Installing that and making a target in scratchbox allows me to compile
the hello-world app (modified to use C++ and iostreams). This all works
as expected and runs fine inside scratchbox. The reason I changed the
example to use C++ is to use the libstdc++.so.6 which the project I am
planning on using will want as well.

Trying to run this on an n810 gets
foo at n810 hello-world $ ./hello 
./hello: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found
(required by ./hello)

foo at n810 hello-world $ ldd ./hello
./hello: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found
(required by ./hello)
        libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x41d70000)
        libm.so.6 => /lib/libm.so.6 (0x41220000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x41e40000)
        libc.so.6 => /lib/libc.so.6 (0x41028000)
        /lib/ld-linux.so.3 (0x41000000)

FWIW the normal C only hello-world compiled with the new toolchain runs
fine on the n810. It doesn't require any newer libraries it would seem.

What is the recommended solution for folks wanting to use the more
recent g++ and toolchain? The new linking method is supported out of the
box for the more recent ld in this toolchain ;)

sbox > g++ --version
sbox-arm-none-linux-gnueabi-g++ (GCC) 4.2.1
> ld --help|grep sty 
  --hash-style=STYLE          Set hash style to sysv, gnu or both


I could imagine doing similar things to the things that were mentioned
on a recent thread about glib. The quick and dirty version being having
a personal lib directory and forcing its use with LD_LIBRARY_PATH in a
little wrapper script for any tools I compile like:
$ gcc4-launch foo
Or forcing the scratchbox to link to 
libstdc++.so.6.0.9 instead of
libstdc++.so.6
and just shoving the libstdc++.so.6.0.9 into /usr/lib and being done
with it.

I thought I'd throw it out there in case someone is using this newer
toolchain and has a solution.
