No.

It should not.

$ qpkg -I -v -l gcc | grep stdc++.so.6
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.4.2/libstdc++.so.6 -> libstdc++.so.6.0.2

Could you please try again and in case programs complain about the missing
libstdc++.so.6, run ldconfig?

Regards,

I upgraded it again and ran into the same problem. The file does exist. I ran
ldconfig, then env-update, then 'source /etc/profile' and I still get the same
error when trying to run a program from the terminal I did all that in.

This happens regularly on multiple systems ive had that have gone
through many gcc versions and is a real pain - sometimes its difficult
to track down and fix.

re-emerge gcc and use "gcc-config -l" and see what profiles you have
available, then reset the profile. source /etc/profile before trying
again and see what happens

If this fails, try "/sbin/fix_libtool_files.sh" and tracking down fixed
paths in the libraries using ldd. This seems the most common cause, and
while the ebuilds should do this, I think that some in the past missed
it, and at some point it causes problems like this.

Have fun

Hmm... Try "gcc-config -l" and post results.

If that doesn't work (some file not found) go to /etc/env.d/gcc and remove
those profiles that are not in use anymore.

I unmerged gcc-3.3.4 because I don't use it. After this, gcc-config still
worked. I upgraded to gcc-3.4.2-r1 again and now gcc-config doesn't work. The
same thing happened last night when I tried (before removing 3.3.4). WTF?

I noticed after sending that the profile is still point to the now-uninstalled
gcc-3.4.1. I changed that and ran ldconfig and still got the errors. I ran
'ldconfig -v' and saw it was still looking the the old gcc profile dirs so I
modified /etc/ld.so.conf and ran ldconfig again. Everything now works. Any idea
what happened?
