The attached patch inserts a '-' between name-version and pid. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/730> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

See ghc ticket http://hackage.haskell.org/trac/ghc/ticket/4134 This applies to the paths in the .cabal file. For ones specified on the command line perhaps just making them absolute would be ok. Ones specified in the global config must be absolute.

#824: cabal install --enable-tests does not install test dependencies. ---------------------------------+------------------------------------------ Reporter: creswick | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.10.1.0 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ Cabal install normally installs all the necessary project dependencies; however, this is not happening for the dependencies specified in the Test- suite stanzas. Here's an example cabal file: {{{ Name: foo Version: 1.0 License: BSD3 Cabal-Version: >= 1.9.2 Build-Type: Simple executable foo main-is: foo.hs build-depends: base , xml == 1.3.7 Test-Suite test-foo type: exitcode-stdio-1.0 main-is: test-foo.hs build-depends: base , QuickCheck >= 2.0 }}} `cabal install` will install xml if necessary, then build foo, but `cabal install --enable-tests` complains that QuickCheck is not available: {{{ $ cabal install --enable-tests Resolving dependencies... Configuring foo-1.0... cabal: At least the following dependencies are missing: QuickCheck >=2.0 cabal: Error: some packages failed to install: foo-1.0 failed during the configure step.

#811: test-suite type not detected ----------------------------+----------------------------------------------- Reporter: basvandijk | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.10.1.0 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- I just installed the latest `cabal`: {{{ $ cabal --version cabal-install version 0.10.2 using version 1.10.1.0 of the Cabal library }}} I'm trying to rewrite the custom test-suite of my [http://hackage.haskell.org/package/threads threads] package to the new Cabal test-suite feature. The original `.cabal` contains: {{{ ... executable test-threads main-is: test.hs ... }}} When I rewrite that to: {{{ ... test-suite test-threads type: exitcode-stdio-1.0 main-is: test.hs ... }}} And than configure it, I get the following error: {{{ $ cabal configure cabal: threads.cabal:60: The 'type' field is required for test suites. The available test types are: exitcode-stdio-1.0 }}} I attached the package. Duncan on `#haskell` figured out that if a .cabal contains conditionals, like the one I have, the bug appears. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/811> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

I had an inadequate patch that was good enough for my experiments (http://osdir.com/ml/cabal-devel@haskell.org/2010-01/msg00029.html) but lack the familiarity with the cabal-install design necessary to implement it properly. Sadly, the patch no longer applies to cabal-install HEAD, and regardless, it would make things a lot easier if it Just Worked out of the box. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/697> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
