Subject: [gentoo-dev] Versioned use flags and preferencing (eg. qt3 / qt4 on same package)

1 Hi all,

5 The above bug brings up 2 issues:
6
7 First, hplip says one thing, but does another with qt3 and qt4 use-based
8 dependencies. This is obviously a bug that needs to be fixed.
9
10 As a user, the second issue it brings up for me is what is the policy
11 applied to the rest of the tree with regards to packages that can use
12 one or more of several options (eg. qt3 or qt4) and have both / all
13 flags specified?
14
15 Do packages that can use both/all always use both/all?
16
17 When both/all flags are specified, which one takes preferences? Always
18 the newer?
19
20 Where is this documented (both from a users point of view, and from a
21 policy point of view)?
22
23 If hplip the only package that can only use one of qt3/qt4 and as such
24 that's why it's the only one with local use flag descriptions, or are
25 there more which just haven't been documented?
