Yes |
| 10 |
multilib, |
| 11 |
|
| 12 |
Ok |
| 13 |
C++ / python ABIs |
| 14 |
|
| 15 |
Aaaaaargh, ehm, should we really throw them in the mix? anyway let me |
| 16 |
see if the same rules apply: |
| 17 |
|
| 18 |
- they have to reside in a separate path if possible? |
| 19 |
|
| 20 |
- the linker must not pick wrong ones in place of the ones you want to use. |
| 21 |
|
| 22 |
- an application using a former abi must link depend on stuff from the |
| 23 |
same place but MAY use stuff from another place. |
| 24 |
|
| 25 |
- is up to the loader pick the right paths on execution |
| 26 |
|
| 27 |
- the dep resolver should ignore packages built using the other |
| 28 |
C++/Python abi. |
| 29 |
|
| 30 |
The issue is more complex and I just ignored it basically because the |
| 31 |
library abi mismatch is an error that should be rectified and not |
| 32 |
something you want and no it isn't because I don't care about binary |
| 33 |
only stuff right now, it's just because looks like there is already too |
| 34 |
much meat w/out something that fits just halfway on the constraints. |
| 35 |
|
| 36 |
or all of them? Then you |

All. |

autotooled programs more or less are already doing the right thing, non |
| 45 |
autotools packages supporting cross development may require some |
| 46 |
additional checks to pass the right target. |
