Bug 298187 – media-gfx/ufraw - please autoenable USE gtk for USE gimp

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description kavol 2009-12-24 10:53:30 UTC]

Hi.

While trying to build ufraw gimp plugin, emerge failed saying:

* to enable gimp support, you must enable gtk support

I have gtk USE flag off globally, as I prefer Qt (when there is a choice ...)

This forces me to add an exception for ufraw into package.use, which I don't like (each bit diverging from the default configuration increases the maintenance pain) and seems quite unnecessary for me - if gimp support is explicitly requested, and gtk is a pre-requisite for it, then it should be autoenabled. I've already seen this behaviour with some ebuilds before, please make my life easier (well, hopefully not just mine :-)) also with this one.

Reproducible: Always

Steps to Reproduce:
1. USE="gimp -gtk" emerge ufraw

Actual Results:  
Calculating dependencies... done!

While we may argue that while GIMP is explicitly enabled, GTK is explicitly disabled, and so emerge could not decide which should take preference, I think the common concept of dependency solving is to pull in the minimal set of things needed to satisfy the demand for things selected to be installed, not to disable to install things that need things which wouldn't be pulled in otherwise.

fixed in cvs, thanks for the suggestion.

  28 Dec 2009; Markus Meier <[e-mail]> ufraw-0.16.ebuild:
