#774: output of 'cabal check' out of sync with cabal syntax ----------------------------------+----------------------------------------- Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.8.0.2 Severity: minor | Keywords: Difficulty: very easy (<1 hour) | Ghcversion: Platform: Linux | ----------------------------------+----------------------------------------- A .cabal file with: Build-depends: base >= 4 when examined with 'cabal check', will return the following warning: """ The following errors will cause portability problems on other environments: * The dependency 'build-depends: base' does not specify an upper bound on the version number. Each major release of the 'base' package changes the API in various ways and most packages will need some changes to compile with it. The recommended practise is to specify an upper bound on the version of the 'base' package. This ensures your package will continue to build when a new major version of the 'base' package is released. If you are not sure what upper bound to use then use the next major version. For example if you have tested your package with 'base' version 2 and 3 then use 'build-depends: base >= 2 && < 4'. """ However, using the suggested "base >=2 && base < 4" results in, "Parse of field 'build-depends' failed." This error goes away if I use "base >=2, base < 4" instead. I think the syntax in the error message is out of date. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/774 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
