No, these are not false positives: # grep -l lib64 /usr/bin/*-config | wc -l; ls /usr/bin/*-config | wc -l 43 89 This is on a typical FC6/x86_64 install maxed by click all in, not @everything, so it is a sample, but it indicates that half the *-config packages *are* architecture specific. > > OTOH you are missing all foo-config scripts that are in foo-devel and > > are arch specific, this outweights any false positives like the ones > > you describe. > > If those are arch-specific then they're broken, Well, anything that does not suit your model is tagged as broken and needs fixing. Maybe it is, maybe not, but the bin64 model does not care, it can live with both, w/o having us to fix all and everything before we can thinkn about multilib. > We can keep refining it all day, but I don't really see the point unless > we're actually going to start filing bugs against the ones which need > splitting. But there is no point in filling bugs against healthy packages.

Well, since I did the math recently, I can tell you that this number is *very* bogus.

Aha, and that's not a problem, huh? yum install foo.x86_64 foo.i386 [...] File boo from foo.x86_64 conflicts with file boo from foo.i386 [...] yum/smart/apt assume a *healthy* repo.

Good, but bin64 has solved the two above, so it's a better solution. > These are unrelated issues which as far as I can tell your solution > doesn't solve either. World hunger? Giving the savings in resources perhaps every devlopers will donate a penny for each saved hour and we'll solve that, too. > If you have to have your $PATH set to /bin64 or /bin according to > whether you're building for 64-bit or 32-bit, to make sure you pick > up the right foo-config or pkgconfig .pc files, then that's still > broken. Why, the developers just hits "goi386" and voila this xterm turned into a pure i386 xterm, where he can work just like on a pure i386 system. That's not broken, that's just great. > And I'm not sure _what_ you're referring to w.r.t firefox.

You install > plugins for one arch or the other, or both. There's no problem here. Yes, fix the issues one by one instead one and for all. You can also fix the pkgconfig issues, and libtool and whatnot, until the next one comes around the corner. That's why I wrote "category-similar issues", there will always be a "firefox" that you will need to run on i386, and "pkgconfig" build tools that will resist to be multilib'd. mplayer on certain codecs come to mind, which would also benefit from allowing both of them to install. mplayer foo fails? Then just try /usr/bin/mplayer foo? It just works w/o packaging mplayer-32 on x86_64? Great. So, it global-solving all in one, or micro-solving one by one. -- Axel.Thimm at ATrpms.net
