#408: cabal install / cabal update should give warning when preferred versions will result in something other than the latest version on hackage ---------------------------------+------------------------------------------ Reporter: tphyahoo | Owner: duncan coutts Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: HEAD Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.3 Platform: | ---------------------------------+------------------------------------------ The natural assumption, unless you know better, is that cabal install -- and especially cabal upgrade -- will install the latest verion of a package on hackage. But the preferred-version machinery invalidates this assumptijon. The suggestions is to emit a warning like {{{ cabal install haxml Downloading HaXml-1.13.3... Note: the preferred version is HaXml-1.13.3 but latest version is HaXml-1.19, so put Build-Depends: HaXml == 1.19.4 in your cabal file if you want that version. }}} I would have this message pop up for both cabal install and cabal upgrade See http://groups.google.com/group/fa.haskell/browse_thread/thread/c39dca259a94… for discussion thread. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/408> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

error with package ghc-6.10.1 and its dependency on process-1.0.1.[01]
by allan 25 Nov '08

25 Nov '08

Dear all I'm attempting to install the latest haddock version via 'hackage' and I'm getting the error: Resolving dependencies... cabal: dependencies conflict: ghc-6.10.1 requires process ==1.0.1.0 however process-1.0.1.0 was excluded because ghc-6.10.1 requires process ==1.0.1.1 I tried re-installing ghc, but I get the same problem. Any suggestions? regards allan -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.

[Hackage] #391: Installing cabal: ./bootstrap.sh: pushd: not found (probably because of /bin/sh)

#391: Installing cabal: ./bootstrap.sh: pushd: not found (probably because of /bin/sh) ----------------------------------+----------------------------------------- Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: very easy (<1 hour) | Ghcversion: 6.8.3 Platform: | ----------------------------------+----------------------------------------- On Ubuntu, trying to install cabal using the "Quick Installation on Unix" instructions at [http://hackage.haskell.org/trac/hackage/wiki/CabalInstall here] says {{{ Setup: At least the following dependencies are missing: Cabal >=1.4&&<1.5, HTTP >=3000&&<3002, zlib >=0.4 ./bootstrap.sh: 24: popd: not found ./bootstrap.sh: 27: pushd: not found }}} and so on. The reason is that bootstrap.sh has a "#!/bin/sh" shebang line, and pushd/popd are Bash extensions, not POSIX shell features, and Ubuntu uses dash, not bash, as /bin/sh (by default). The fix is to make bootstrap.sh either not use Bash-specific extensions, or (easier) make the top line of bootstrap.sh say "#!/bin/bash" instead of "#!/bin/sh". [It might be wise to make the same change in all other files that use Bash extensions; the tool "checkbashims" might be useful here.] -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/391> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
