Hi list. Hackage cannot build my package, because for some reason it will only use base-4.9.0.0, which does not satisfy the dependencies of some of my dependencies. So, I was trying to figure out how to report my own builds. However, when I use the "cabal report" command, cabal take my username and password, and then (so far as I can tell) does nothing. I tried increasing the verbosity, as well as upgrading to the latest version of cabal, but this did not work. And I can seem to find the documentation for this feature. Please advise.
But the first thing you could try is to call cabal with the '--allow-newer' option, which allows newer library versions then specified by the constraints. This will only work if the newer library versions don't containt breaking changes, so it's just a way to get going for the moment but no real solution.
About the reporting, there's no other way then to contact every single developer of the breaking libraries.
Well, I know the reason it cannot build with base-4.9.0.0: My library is fully compatible with base (>=4.6 && <4.10), but it depends on the Gloss library (>=1.7 && <1.10). I cannot use Gloss 1.10, because Gloss 1.10 has a breaking API change on one of the Gloss functions I use in my library, which I could only get around if I used a lot of conditional code, which I haven't done yet. However, only Gloss 1.10.* is compatible with base-4.9.0.0. http://hackage.haskell.org/package/mars http://hackage.haskell.org/package/mars-0.2.1.0/reports/ Hackage, it is seems, will only try building with base-4.9.0.0, rather than reverting to an earlier version and compiler. The package builds just fine on my system, using an earlier base and compiler. So, I guess the question is, do I have to further restrict the dependencies of my library (to exclude 4.9.0.0) just because one of my dependencies cannot handle that version? -- https://qlfiles.net My PGP public key ID is 0x340EA95A (pgp.mit.edu).
