[gentoo-user] Version conflicts when mixing arch and ~arch
Hi, A portage question, to satisfy my own curiosity i.e. I know how to fix the problem I had, but I'd like to know if I fully understand how to use portage in a case like this: My desktop is a mostly stable x86 machine, but I use e17- as my wm. x11-wm/e depends on evas which has a hard dependency on cairo: cairo? ( =x11-libs/cairo-1.2 ) I had to unmask e, evas and cairo to get this to emerge. I also have x86 pygtk and pycairo already installed, pycairo has a hard dependency on cairo-1.0* =x11-libs/cairo-1.0* emerge world wants to downgrade cairo to 1.0* to satisfy pycairo, then the next emerge world wants to upgrade it to 1.2* to satisfy evas = a version conflict which yo-yos back and forth. The fix is obviously to keyword pycairo to ~x86 to give consistent dependencies. This is harder than it could be: pygtk could also have had it's own conflicts, and it takes several 'emerge -pv world' and reading ebuilds to get the whole picture. And this is something portage could have figured out itself. emerge -p world had to parse the entire portage tree anyway, it could easily check for versioning conflicts while doing it and display a message to the user, much like blockers do currently. I get it that portage likely can't suggest resolutions but it would be nice to see in one display that evas and pygtk requires mutually exclusive versions of cairo. Can portage do this? Is it something useful that warrants a feature request? Or am I missing an option in the man page even though I've read it 30 times? :-) alan -- gentoo-user@gentoo.org mailing list

That means that the latest stable portage still won't detect it but latest ~arch portage should...

My notebook runs ~x86, meaning I can test the latest portage there and keyword portage on the desktop if everything seems fine. Thanks for the info alan -- gentoo-user@gentoo.org mailing list
