I think a lot of the less sophisticated gentoo users are struggling with revdep-rebuild's. It is not so easy to figure out what is going on. There are a number of issues that could be at fault when a revdep-rebuild fails in cleaning out the system. would it be possible to keep the information about the most recent revdep-rebuild, and if it is the same as what the current revdep-rebuild wants to prescribe, at least to automatically switch on the verbose mode to tell me what libraries are broken? even better, it would be nice if it used some intelligence to try to tell me exactly why it wants to rebuild the package again. [...and may I ask why gcc updates cannot be fully automatic? why do I have to read the update guide and learn about special incantations?... ] sorry, I always sound like I am complaining. gentoo is an amazing system, but I guess a bug system is not for kudos, but for suggestions. thanks guys. regards, /iaw

Eh, revdep-rebuild is a bash script using ldd to find out broken linkage. If something is missing shared library dependencies, then it tries to re-emerge the package; so I kinda don't see what kind of intelligence would you expect from this tool. The advice it gives you on failure is about as good as it can be. (And no, gcc upgrades can't be automatic, because switching to ABI-incompatible gcc can break your system).

You might want to emerge rsvg to fix this. of course, I have no concept of how easy or difficult this would be. I am speaking purely from an ordinary end user perspective. This would make my life easier diagnosing the state of my system. > (And no, gcc upgrades can't be automatic, because switching to ABI-incompatible > gcc can break your system). > Hmmm...the steps that are described in the gcc updating guide seem all easy to automate: fix-libtool, revdep-rebuild on libstdc++, etc. . Why can't a post-emerge chained shell script execute these for ordinary users automatically? regards, /ivo
I think the situation is a lot better now due to subslots. Thoughts?
