#844: Cabal reports "cabal: internal error: the package contains a library but there is no corresponding configuration data" when there exists no library in the cabal file ------------------------------+--------------------------------------------- Reporter: fushunpoon | Owner: Type: defect | Status: new Priority: low | Milestone: Component: Cabal library | Version: 1.8.0.6 Severity: minor | Keywords: Difficulty: easy (<4 hours) | Ghcversion: Platform: Mac OS | ------------------------------+--------------------------------------------- Changes (by fushunpoon): * priority: normal => low * difficulty: normal => easy (<4 hours) * severity: normal => minor Comment: I have found out precisely the reason why this error is displayed: The `sdlexprs.buildinfo.in` file that I wrote did not declare the `cc- options` line under the specific executable `test`. This means that by default it was treated as build information for a library as opposed to an executable when the `sdlexprs.buildinfo` file is consulted when doing a `cabal build`. This problem deserves a better error message earlier on, perhaps as a warning, that even though no `Library` sections exist in the cabal file, the consulted `*.buildinfo` file does. This surely is an inconsistency on part of the user. To say that the project "contains a library" is misleading and is confusing, especially when the `.cabal` file is supposed to be the definitive package description file. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/844#comment:2 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
