This fuctionality is only enabled for EAPI=5-hdepend and should not affect other EAPIs. Changes: |
| 7 |
|
| 8 |
1. HDEPEND dependencies. These are build-time dependencies which have to be installed on the build machine (host, ROOT=/). |
| 9 |
|
| 10 |
2. DEPEND dependencies now always refer to packages in ROOT (target); destination of DEPEND is no longer determined by --root-deps. |
| 11 |
|
| 12 |
3. targetroot USE flag. This is a special USE flag which is automatically enabled when the ROOT for a package is different than /. The primary use case for this is to make a package depend on itself in order to cross-compile. The dependency needs to be conditional otherwise the package may not be installable for ROOT=/. |
| 13 |
|
| 14 |
The flag still needs to be added to IUSE to work. Example: |
| 15 |
|
| 16 |
EAPI=5-hdepend |
| 17 |
IUSE="... targetroot ..." |
| 18 |
HDEPEND=".... |
| 19 |
targetroot? ( ~${CATEGORY}/${P} )" |
| 20 |
|
| 21 |
Also, the flag is implemented such that it is not considered by --newuse, which makes sure that emerge from within the target system will not attempt to rebuild every cross-compiled package. |

I've tested this patch with packages in my cross-compile overlay which contains some packages using the new support: |
