Package: libstdc++6
Version: 4.1.1-13
Severity: important
I have problems with version 4.1.1ds1-13 of package libstdc++6 as this
breaks some older applications. If you have the sources, you can
recompile, if not ... what is the suggested solution?
What happens is this:
[EMAIL PROTECTED] ldd foobar
./foobar: /usr/local/gnat/lib/libgcc_s.so.1: version `GCC_4.2.0' not
found (required by /usr/lib/libstdc++.so.6)
This looks to me like the new library demands version GCC_4.2.0 from
libgcc_s.so.1, which in my case cannot provide this. How can I get
foobar going with the new libstdc++? I can recompile foobar as I have
the sources to it, but I cannot easily
recompile /usr/local/gnat/lib/libgcc_s.so.1 which foobar depends on
(this is from AdaCore's binary distribution of GNAT).
With the 4.1.1ds1-13, it looks like this:
[EMAIL PROTECTED] strings /usr/lib/libstdc++.so.6 | grep ^GCC
GCC_3.3
GCC_4.2.0
GCC_3.0
[EMAIL PROTECTED]
With 4.1.1-11 everything was fine:
[EMAIL PROTECTED] strings /usr/lib/libstdc++.so.6 | grep ^GCC
GCC_3.3
GCC_3.0
[EMAIL PROTECTED]
Why was this dependency introduced? Is there any way around it?
In the libgcc_s.so.1 supplied by AdaCore, it looks like this:
[EMAIL PROTECTED] strings /usr/local/gnat/lib/libgcc_s.so.1 | grep ^GCC
GCC_3.0
GCC_3.3
GCC_3.3.1
GCC_3.4
GCC_3.4.2
Is this a change in libstdc++6 that will become necessary in the future
anyway and there's no way round it, or is it a bug in the latest version
of the libstdc++6 package?
Thanks for any hints in advance.

Not a bug; you're using a locally installed libgcc_s.so.1 on your
system, which doesn't have this symbol.
Debian's libstdc++6 explicitely depends on libgcc1 (>= 1:4.1.1-12),
which provides this symbol.
