In short it is like this : |
| 5 |
|
| 6 |
USE="gtk gtk2" |
| 7 |
|
| 8 |
Use gtk+ UI if available (this might be gtk+-1 or gtk+-2, depending on |
| 9 |
the application & version), if there's both gtk+-1 and gtk+-2 UIs in the |
| 10 |
package build the gtk+-2 UI. |
| 11 |
|
| 12 |
USE="gtk -gtk2" |
| 13 |

USE="-gtk -gtk2" |

Always disable optional gtk+ UI support (doesn't matter if it's gtk+-1 |
| 21 |
or gtk+-2). |
| 22 |
|
| 23 |
USE="-gtk gtk2" |
| 24 |
|

Illegal for builds that have an optional gtk+-1 or gtk+-2 UI. 'gtk2' is |
| 26 |
a qualifier for 'gtk' and should have no effect in this case, the gtk+ |
| 27 |
UI building has been disabled with '-gtk'. This logic is flawed in quite |
| 28 |
a few ebuilds and this combination results in undefined behaviour and |
| 29 |
should be fixed. |
| 30 |
|
| 31 |
Could be considered legal for builds that have a non-optional gtk+-1 or |
| 32 |
gtk+-2 gui. Although in this case for simplicity and consistency sake i |
| 33 |
would suggest we just default to the most mature and/or recent one of |
| 34 |
the UIs and make it use the 'gtk' USE flag only. In time we should be |
| 35 |
able to phase out the gtk2 USE flag altogether (it was meant as a short |
| 36 |
transition flag). |
| 37 |
|
| 38 |
|
| 39 |
The gtk/gtk2 USE flag combination has been a source of confusion over |
| 40 |
time, in retrospect this may not have been the best solution to the |
| 41 |
mixed packages problem at the time (both gtk+1 and gtk+-2 UIs in one |
| 42 |
package). It worked sufficiently up to now and changing it would |
| 43 |
probably more trouble than that would be gained from it. |
| 44 |
|
| 45 |
In a future similar case this would most likely be done in a different |
| 46 |
way. |
| 47 |
|
| 48 |
For now i suggest devs trying to fix their ebuild's gtk/gtk2 handling to |
| 49 |
contact one of the gnome devs to work out the best fix. |
