#312: Allow ${arch} var in install paths ----------------------------+----------------------------------------------- Reporter: larsv | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Cabal-1.4 Component: Cabal library | Version: 1.2.3.0 Severity: minor | Resolution: Keywords: | Difficulty: very easy (<1 hour) Ghcversion: 6.8.2 | Platform: ----------------------------+----------------------------------------------- Changes (by duncan): * difficulty: easy (<4 hours) => very easy (<1 hour) * summary: Multiple architectures under .cabal/ => Allow ${arch} var in install paths * milestone: => Cabal-1.4 Comment: This is just a matter of adding an `ArchVar` constructor to `PathTemplateVariable` in the `Distribution.Simple.InstallDirs` module. Then the `Arch` should be passed to `substituteTemplates` along with the `CompilerId` etc. This will make it possible for users to use `${arch}` in the install dirs like `--libdir` (or the equivalents in the cabal-install config file). Note that we're not proposing to actually change the default install paths, just to make it easy for users to do this themselves. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/312#comment:1 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
