#397: make cabal --cabal-lib-version="" take a dependency or a specific number ---------------------------------+------------------------------------------ Reporter: duncan | Owner: Type: enhancement | Status: new Priority: low | Milestone: Component: cabal-install tool | Version: 1.2.3.0 Severity: minor | Keywords: Difficulty: normal | Ghcversion: 6.8.3 Platform: | ---------------------------------+------------------------------------------ The `--cabal-lib-version=` flag currently takes a specific version number. It could easily be like `--constraint=` or like `cabal install "foo < 2"` and take a dependency or a specific version number. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/397> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

patch applied (cabal): Make auto-generated *_paths.hs module warning-free.

Thu Nov 6 06:27:34 PST 2008 Thomas Schilling <nominolo(a)googlemail.com> * Make auto-generated *_paths.hs module warning-free. On newer GHCs using {-# OPTIONS_GHC -fffi #-} gives a warning which can lead to a compile failure when -Werror is activated. We therefore emit this option if we know that the LANGUAGE pragma is supported (ghc >= 6.6.1).

darcs patch: Make auto-generated *_paths.hs module warning-free.

Hi, the attached patch fixes a GHC validate build error on Windows. The issue is that an auto-generated _paths.hs file was not warning free and caused a compile failure since GHC's validate uses -Werror. Cheers, Thomas

[Hackage] #389: ld-options not properly escaped when passing them to ghc

#389: ld-options not properly escaped when passing them to ghc ----------------------------------+----------------------------------------- Reporter: duncan | Owner: Type: defect | Status: new Priority: normal | Milestone: Cabal-1.6 Component: Cabal library | Version: 1.0 Severity: normal | Keywords: Difficulty: very easy (<1 hour) | Ghcversion: 6.8.3 Platform: | ----------------------------------+----------------------------------------- In constructing the `ghc` command line, the `ldOptions` are passed directly to `ghc` without any escaping. Obviously they should be escaped with the `-optl` prefix. This bug has been in Cabal since support for ld options was introduced in version 0.4, which was released in January 2005. We got away with it for nearly four years because ghc understands most common ld options like `-lfoo` or `-Lbar`. It cropped up because recent versions of `libcurl` (at least in Ubuntu Intrepid) supply a `pkg-config` file which instructs clients to use `-Wl ,-Bsymbolic-functions` when linking to `libcurl`. Obviously this is not a flag that ghc understands. The bug manifests itself as: {{{ ghc-6.8.3: unrecognised flags: -Wl,-Bsymbolic-functions }}} The fix is of course trivial: {{{ - ++ ldOptions bi + ++ ["-optl" ++ opt | opt <- ldOptions bi] }}} Thanks to kowey for discovering it and helping diagnose the source of the problem. It'll be fixed in Cabal-1.6.0.2. I thought I'd document it here partly because it's interesting to find such a bug that went undiscovered for so long. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/389> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
