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).

So you're saying that gloss <1.10 builds with base 4.9? Then ask the maintainer of gloss if there would be any issues of supporting base 4.9 with gloss 1.9. Most likely they didn't bother to support newer ghcs with older gloss versions. But If they're nice they might release a new gloss 1.9 version supporting base 4.9.
