Re: Re: Package Dependcies List on Techbase
Please excuse the Top-Post, my suggestion is VERY short: The terminology Optional Dependency sounds like a good term for these situations. (At least to me, a native 'en-us' person.)

Yes, the comment says that it is for mobile, but Required is a strong term, and I don't think the comment in its current form makes it clear enough that Required might not actually mean what it says. In this particular example, QtDeclarative will not be needed for someone building for the desktop. This will be the default build option for many people, so I think it needs to be stated more explicitly that Required may actually mean Optional. I can appreciate that you may not have time to write a parser for cmake conditionals. But if conditional dependencies are going to be listed as Required, I think there should be a clear statement at the top of the page that Required doesn't necessarily mean what it says, and may mean optional, depending on what conditional settings are used.

These are really useful pages - thanks for taking the time to do this! 1) One observation is that in some cases, different modules which depend on each other require different versions of the same dependencies. It would be nice if there was some correlation between these. For example, kdelibs requires shared-mime-info = 0.60, while kdepimlibs requires shared-mime-info = 0.30. Since kdepimlibs depends on kdelibs, shared-mime-info = 0.60 is effectively required for kdepimlibs as well, even if its CMakeLists.txt only asks for 0.30. 2) Is QtDeclarative actually REQUIRED for kdepim?

So one I idea I have is to process all the modules together and do some kind of factoring of all the packages needed. Then make another page listing all the packages and in what modules they are needed. On my todo list. 2) Is QtDeclarative actually REQUIRED for kdepim?

Package Dependcies List on Techbase
Howdy, I started putting the list of package dependences (arranged by module) onto Techbase. http://techbase.kde.org/Getting_Started/Build/Requirements The tables on the subpages there are generated by a perl program I wrote. That program reads the CMakeLists.txt files inside a module and generates wiki content I then copy+paste into Techbase. Please review for accuracy. For example: Why are attica and phonon REQUIRED for kde-runtime?? I'll be finishing up the list in the coming days.
