There's no need to run revdep-rebuild, whatever you do it will be redundant. The notices you are seeing are primarily intended for when you explicitly emerge packages that other packages may link to. So everything that might be relevant to the notice you see is going to be recompiled anyway when you run 'emerge -e world'. As previously noted on this list, the mention of using revdep-rebuild as a shortcut when upgrading gcc was intended for the move from 3.3 to 3.4 *only*. The specifics of that upgrade made this shortcut possible, in all other upgrades you definitely don't use it. i.e. the guide is in need of an uodate to make this explicitly clear. If you need more info, ask Richard for the inside dope - he's the resident gcc expert around here :-) alan -- gentoo-user@gentoo.org mailing list

The recommended steps are: # emerge -eav system # emerge -eav world While emerging my system I received a message suggesting I run revdep-rebuild: warning - be sure to run revdep-rebuild now Um, I believe you can ignore this. The emerge -eav world will rebuild all packages...there is nothing that revdep-rebuild will catch that world won't. Now if you want to keep /using/ the system while it is rebuilding, you could do: emerge -eav system # if already complete, don't repeat revdep-rebuild --library libstdc++.so.6 emerge -eav world The revdep-rebuild command will recompile all C++ applications, and will take a damn long time to run. But less time than rebuilding world, and once it completes, your C++ apps should at least be sane. Otherwise you might get ABI conflicts while the world rebuild is going on. Of course, those same C++ apps are going to be rebuilt during the world step...which is kind of lame. There are some tricks you can use to avoid rebuilding things twice...search the archives of this list for ideas. -Richard -- gentoo-user@gentoo.org mailing list
[gentoo-user] gcc upgrade from 3.x to 4.x, when should I run revdep-rebuild?
I'm upgrading my gcc from 3.x to 4.x. I've done the gcc switching, and now I'm updating my system. The recommended steps are: # emerge -eav system # emerge -eav world While emerging my system I received a message suggesting I run revdep-rebuild: warning - be sure to run revdep-rebuild now My question is, should I run revdep-rebuild right after emerging the system, or should I wait until after I emerge world? My concern was that in between, my system is in an unstable intermediate state, and it might be damaged by a revdep-rebuild in between. -- gentoo-user@gentoo.org mailing list
