If libressl and openssl would have matching ABIs, that wouldn't be necessary and you could what virtual/libudev does, i.e. explicit subslot deps. -- Best regards, Michał Górny pgp9TTRFD6wY2.pgp Description: OpenPGP digital signature
Re: [gentoo-dev] [RFC] LibreSSL, introduce virtual/openssl
Regarding the last libav discussion I think we should also go with a "libressl" USE flag instead of creating a virtual that makes handling SUBSLOTs impossible.

It does use the dep string for the ebuild, after it has rejected the installed instance and decided to pull in the ebuild instead. > That's what I understand from Michał's comment (quoting him): > >> 1. if you have dynamic-deps enabled, portage will want to install both >> ffmpeg (because of :=) and libav (because of ||).

It does consider the original dep. However, it also uses various heuristics when making choices for || deps, and the fact that an instance of ffmpeg is currently installed is taken into account in the heuristics. -- Thanks, Zac

Lots of dev-perl packages have specific minor version dependencies on dev-lang/perl, maybe because sometimes the package is included in perl and sometimes not. It's a f*ing mess. You have to look up all your installed dev-perl packages manually and find which ones are either too old to know about perl-5.20 or not compatible with it, and then you have to unmerge those manually. > Kinda defeats the purpose of catalyst in the first place. The proper way is to build stage1+2+3 yourself, then this mess doesn't happen. But like you I too cheat a little, and have to deal with the mess. //Peter

My question was: _why_ when portage knows what package to rebuild doesn't it use the dep string from the ebuild ? That's what I understand from Michał's comment (quoting him): > 1. if you have dynamic-deps enabled, portage will want to install both > ffmpeg (because of :=) and libav (because of ||).

If you want to use --dynamic-deps=n, then you may need to fix some dependencies of installed packages, which you can do by running emerge @changed-deps. There's also a --changed-deps [1] option that can be applied to @world updates, which will be included in Portage 2.2.16.
