Re: [arch-general] PKGBUILD "provides" not handled correctly?

Thanks for all your quick replies. Immediately after firing off this email, I thought it would be something like this, but for some reason I didn't bother to read the manpage :( Some would have considered this reason enough for a RTFM response. It's wonderful to see that these types of responses are very rare in the arch community. Again, thanks for your help. Cheers, Norbert Jan Steffens [2012.05.01 2134 +0200]:

Hi folks,

I have just run into a weird problem.  I have a machine that isn't too happy with the 3.3.x kernel series.  So I'm running linux-lts on it, but that one is meant for servers, so isn't as responsive as one would like on a desktop system. So I've decided to throw a little PKGBUILD together that compiles linux-lts with CONFIG_HZ set to 1000 but is otherwise unchanged from the version in ABS.

To ensure this tweaked lts kernel does not get inadvertently overwritten by a linux-lts upgrade, I've changed the package name in the PKGBUILD to linux-lts-local.  I've added "linux-lts" to the conflicts/provides/replaces lists in the PKGBUILD to ensure that I do not install linux-lts and linux-lts-local at the same time and to ensure that all packages that rely on linux-lts continue to have their dependencies satisfied...or so I thought.

Compiling the tweaked lts kernel and installing this kernel instead of linux-lts on my laptop with intel graphics works without problems.  My office desktop is a machine with an NVIDIA card and I'm using nvidia-lts as my graphics driver. When trying to replace linux-lts with linux-lts-local using pacman -U, pacman complains that nvidia-lts requires linux-lts>=3.0.0 and refuses to continue. Now I'm confused: linux-lts-local provides linux-lts, and the version is 3.0.29-1.  So why does pacman complain?  Any pointers are much appreciated.

Cheers, Norbert

If you don't specify a version to provide, the provides will be unversioned and fail any version comparisons.

So: provides=("linux-lts=$pkgver-$pkgrel")
