 sterni | bglgwyng: Haskell dependencies need to be propagated, so any given package sees its transitive Haskell dependency closure. random is pretty common, so probably somewhere the non overridden random is visible. Cabal is free to pick any version within bounds. | 10:58:17 |
| sterni | hip doesn't have bounds on random at all, so maybe it picks another version? You can force it a specific version via the --constraint configure flag, but you'll likely run into trouble with this since Haskell isn't designed for multiple versions of the same package being linked into the same end product. | 10:59:55 |
| sterni | The only robust way of overridding a package that occurs multiple times in the dependency closure of a give package is to use overrideScope and recompiling (a large portion of) the dependency closure. | 11:00:42 |
| sterni | or do you mean something else by "not affected by"? | 11:01:07 |
 bglgwyng | No. your understanding is correct | 11:02:43 |
| bglgwyng | I should check for it now, but I'm so sure that I override every package depends on random with the same version of random | 11:03:14 |
| bglgwyng | So transitively depended random should be the same | 11:03:37 |
| bglgwyng | Even if I did so, does the problem you describe can occur for some reasons? | 11:04:05 |
| bglgwyng | Warning:
This package indirectly depends on multiple versions of the same package. This is very likely to cause a compile failure.

I got this message, and I override random for every package depending on it
