#221: a generic way for cabal-install to specify external dependencies ----------------------------+----------------------------------------------- Reporter: guest | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: Linux | ----------------------------+----------------------------------------------- Cabal-install needs a way to specify external dependencies, so that re- install can be made as automatic as possible. The fact that Cabal records the 3rd digit version in the path indicates a diligent user has to re- install all the packages on every new 3rd-digit dot release. Exanples are HDBC-ODBC and regex-pcre. This issue was raised in http://www.mail-archive.com/haskell-cafe@haskell.org/msg37001.html It was discussed before and Tim had one suggestion: http://www.mail-archive.com/haskell-cafe@haskell.org/msg33790.html I suggest to have a config-replacement file (or a section in .cabal/config) as such: package: SDL include-dirs: c:\libs\SDL\include When cabal-install attempts to install SDL in this case, it will replace the line "include-dirs" in <package>.cabal with what is suggested in the config-replacement file. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/221 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
