Arch Linux

The location of a library shouldn't matter, as long as it's in ld.so.cache correctly.

[jvinet@mars jvinet]$ ldconfig -p | grep libstdc++
libstdc++.so.6 (libc6) => /usr/lib/libstdc++.so.6
libstdc++.so.5 (libc6) => /usr/lib/libstdc++.so.5
libstdc++.so (libc6) => /usr/lib/libstdc++.so

If you have the latest gcc and gcc-compat packages installed, you should have output like mine above. If not, try removing any libstdc++ links from /lib and re-running ldconfig.

[root@arch lib]# ldconfig -p | grep libstdc++
libstdc++.so.6 (libc6) => /usr/lib/libstdc++.so.6
libstdc++.so (libc6) => /usr/lib/libstdc++.so

I removed all symlinks and that's my output. Still problems.

When I add the symlink (/lib/libstdc++.so.5 -> /usr/lib/libstdc++.so.5) everything works, and I get the same output as you.

I won't add that (redundant) symlink unless I can reproduce the error myself.

What does this display for you?

[jvinet@mars jvinet]$ ldd /opt/mozilla-firefox/lib/mozilla-1.6/firefox-bin | grep libstdc
libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x404f8000)

And what error does firefox spit out when you try to run it?

Funny.. My symlink dissappeared and everything works now... Sorry for an invalid bug report!

No worries, glad it fixed itself! :)

On a side note, the gcc-compat package will likely be disappearing soon. I'll include the old libstdc++ libs in the gcc package itself.
