I am thinking about a solution for those similar to current ruby idea and already implemented for |
16 |
cross-compilation in my multilib-portage branch of portage. The very short version: |
17 |
|
18 |
Set the needed details in the ebuilds, where needed, in case of revdep-rebuild, either adjust the |
19 |
SLOT var for each change requiring a rebuild of depending packages or using some new var, e.g. |
20 |
API_SLOT for this. Ebuilds depending on packages like python or perl should define the range of |
21 |
versions they support. |
22 |
|
23 |
Now portage generates a (use_expanded) list of USE flags for depending packages, e.g. for a package |
24 |
depending on python-2.6 and 2.7 it adds something like PYTHON_DEPEND="pyhon26 python27" to the list |
25 |
of USE flags. If there is only one dependency installed (like perl or changing libs), this could be |
26 |
a hidden USE flag. |
27 |
|
28 |
When the dependency is now updated, the USE flags will change, so in case of portage, a --newuse |
29 |
will catch those changes and shows those packages in the list of packages, that need to be emerged |
30 |
again. |
31 |
|
32 |
In case of slotted dependencies (like python, ruby or php), this would also allow the user to define |
33 |
per package, if he wants support for one or more slots of e.g. python. |
