Greetings all,
I have gcc 3.4.5-r1, and I'm trying to do a system update which wants
to give me 3.4.6-r1. Unfortunately, no matter what I do, Portage seems
intent upon installing libstdc++-v3-3.3.4. I don't want this package.
I don't have any binary packages installed, and I've rebuilt
everything to use the new libraries.

I've seen the forum thread at
"http://forums.gentoo.org/viewtopic-t-452675.html" which suggests
doing an "emerge -pt world" to find out what package is depending upon
libstdc++-v3, but there isn't one. It reports that it wants to install
gcc, then libstdc++-v3. That's it. "equery depends libstdc++-v3" also
tells me that nothing depends on libstdc++-v3.

No, before anyone asks, it isn't in my world file either

"equery depends" only check direct dependencies. Try:

awk '{print "equery depgraph "$1"|grep libstdc++ && echo "$1}' \
/var/lib/portage/world | sh

Or, easier (and faster), emerge app-portage/portage-utils and then do:

qdepends -Q libstc++

Or, you could cheat and do the much faster DIY version:

grep -l libstdc++ /var/db/pkg/*/*/DEPEND

Then cat the resulting file(s) and see what use flag causes it to be pulled
in.

depends: i'm such a fatty, could not

# grep -l libstdc++ /var/db/pkg/*/*/DEPEND
<no output>


So although you've shown me a cool new package (qdepends is a lot
faster than equery) which I must take some time to learn, this has not
increased my information about libstdc++-v3.

Oh, here's a weird thing which I forgot to mention in my original
post: before I upgraded system, I tried "emerge -up gcc", and it
wanted to install libstdc++-v3 AFTER gcc. If I did "emerge --nodeps
- -up gcc" then it didn't want to install libstdc++-v3. Almost like some
kind of dependency being built backwards or something, but why would
gcc depend on libstdc++-v3?

The newer version of gcc's libstdc++ that you're installing has ABI
differences to the older version. This legacy ABI is maintained in
libstdc++-v3.

So either you mask the new version of gcc, or put up with having the new
gcc and libstdc++. Or, you manually try to weed out all the apps that
use the old libstdc++. Good luck with that!

Since 3.4.6-r1 has libstdc++-v3 as a postinstall dependency, I see only
two ways not to get libstdc++-v3:
a) don't update to 3.4.6-r1
b) use an overlay and modify the 3.4.6-r1 ebuild

Sorry not being a bearer of happier news,
Marc

I guess I can spare the disk space. None of my apps actually need it,
so presumably the old libstdc++ won't get loaded into RAM, which is a
bigger concern for me. As long as there's a sensible explanation, I
guess I'll just leave it alone (it isn't really worth bothering with a
custom ebuild).

Thanks,
Chris
