Here (Slackware 13.37) I have this:
Code:
bash-4.1$ firefox --version
Mozilla Firefox 13.0.1
bash-4.1$ ldd /usr/bin/firefox
linux-gate.so.1 => (0xffffe000)
libpthread.so.0 => /lib/libpthread.so.0 (0xb789c000)
librt.so.1 => /lib/librt.so.1 (0xb7893000)
libdl.so.2 => /lib/libdl.so.2 (0xb788f000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb77a6000)
libm.so.6 => /lib/libm.so.6 (0xb777f000)
libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0xb7763000)
libc.so.6 => /lib/libc.so.6 (0xb7600000)
/lib/ld-linux.so.2 (0xb78e1000)
bash-4.1$
But I noticed that libstdc++.so.6 is provided by cxxlibs-6.0.14 of which package description says:
Code:
cxxlibs: cxxlibs (C++ shared library compatibility package)
cxxlibs:
cxxlibs: This package contains the shared libraries needed to run dynamically
cxxlibs: linked C++ binaries linked with older versions of libstdc++.
And the content of the package confirm that:
Code:
usr/i486-slackware-linux/lib/libstdc++-3-libc6.2-2-2.10.0.so
usr/i486-slackware-linux/lib/libstdc++.so.5.0.7
usr/i486-slackware-linux/lib/libstdc++-3-libc6.1-2-2.10.0.so
usr/i486-slackware-linux/lib/libstdc++.so.4.0.0
So do you have that compatibility package (dunno how it is called in kubuntu, though)?
