[Hackage] #604: a feature to explicitly allow multiple versions of a single dependency

#604: a feature to explicitly allow multiple versions of a single dependency ----------------------------+----------------------------------------------- Reporter: guest | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.6.0.1 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: 6.10.1 Platform: Linux | ----------------------------+----------------------------------------------- I wanted to build two executables for comparing the performance difference between happstack-server-0.3.4 and happstack-server-0.4. So I wrote below cabal file but found that cabal cannot build what I want. Here is the output for "cabal configure": {{{ aycan@fgt:~/haskell/tests/happstack-tests$ cabal configure Resolving dependencies... Configuring happstack-tests-0.1... cabal: At least the following dependencies are missing: happstack-server ==0.4 && ==0.3.4 }}} {{{ Name: happstack-tests Version: 0.1 Author: Aycan iRiCAN <aycan.irican(a)core.gen.tr> Stability: Experimental Category: Web Synopsis: Tests for Happstack Packages Cabal-version: >= 1.6 Build-Type: Simple Flag base4 Description: Choose the even newer, even smaller, split-up base package.

Specific license field
by Neil Mitchell 10 Nov '09

10 Nov '09

Hi, I just got approached by Fedora maintainers with the query that HLint doesn't specify it's license fully. The License field in the cabal file says "GPL", and the LICENSE file has a copy of the GPL v2, but I never say GPL version 2, or GPL version 2 and above etc. What is the Cabal approved way to indicate your licensing constraints? I suspect all other distro's packaging HLint have just guessed, or gone GPL 2 because that's clearly a subset of what I might have intended. Thanks, Neil PS. For anyone who stumbles across this email, the intention was to license HLint under the GPL v2, but if that license doesn't suit someone, email me.

[Hackage] #403: Bad error message when running ./configure fails to find sh
by Hackage 10 Nov '09

#403: Bad error message when running ./configure fails to find sh ----------------------------------+----------------------------------------- Reporter: duncan | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: HEAD Severity: minor | Keywords: Difficulty: very easy (<1 hour) | Ghcversion: 6.10.1 Platform: Windows | ----------------------------------+----------------------------------------- For `build-type: Configure` we have to run `./configure`. On windows this will very often fail of course because they usually lack the `sh` program. Currently the error message users get is not great: {{{ sh: runGenProcess: does not exist (No such file or directory) }}} It would be nicer if they got a better message. Perhaps the way to do that is to catch the `DoesNotExist IOException` and re-throw a better message. Alternatively we could explicitly check for `sh` before invoking it. If it's not found on Windows then we could report that the package needs a unix-style command shell program eg from `mingw` to build. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/403> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
