#945: Fails to find install plan for containers package tests ---------------------------------+------------------------------------------ Reporter: tibbe | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.14.0 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: 7.4.1 Platform: Linux | ---------------------------------+------------------------------------------ The containers package has a test-suite section which seems to create a cycle when building the package. Could it be that Cabal treats the package as one unit instead of treating the library and test-suite sections separately, which should remove the cycle. {{{ $ cabal install --enable-tests -v3 searching for ghc in path. found ghc at /usr/local/bin/ghc ("/usr/local/bin/ghc",["--numeric-version"]) /usr/local/bin/ghc is version 7.4.1 looking for tool "ghc-pkg" near compiler in /usr/local/bin found ghc-pkg in /usr/local/bin/ghc-pkg ("/usr/local/bin/ghc-pkg",["--version"]) /usr/local/bin/ghc-pkg is version 7.4.1 ("/usr/local/bin/ghc",["--supported-languages"]) ("/usr/local/bin/ghc",["--info"]) Reading installed packages...

The problem is actually not a solver problem, as I first thought, but a more fundamental problem in Cabal. It's also independent of using the modular solver. So the problem here is that the testsuite of containers *indirectly* depends on containers again. The question is whether this should be allowed. Fixing this would indeed mean that we should be able to build containers first, then the dependencies of the test framework, and finally the testsuite. We'd indeed have to introduce a possibility to build flavours or parts of packages in isolation. It'd for example be nice to be able to separately build non-profiling and profiling versions of a lib. However, I'm afraid this change will take some more careful design, so don't expect a quick fix. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/945#comment:2 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

I generally hack on lower-level libraries and my test and benchmark dependencies indirectly depend on the library I'm working on quite often nowadays (e.g. Criterion depends on unordered-containers and I use Criterion to benchmark unordered-containers.) -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/945#comment:3 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
