Problems with install-includes
by George Giorgidze 23 Jan '09

23 Jan '09

Hi, In my project I am using C include/header files that are hierarchically nested into folders. These header files are used to compile the Haskell package and everything is fine with the compilation process. I want these include files also to be installed with the package. From the online documentation of Cabal I learned that there exists specific field for this purpose called install-includes. However, it does not work when include files are hierarchically nested into folders. Here is relevant part of the cabal file I am using. include-dirs: cbits/sundials/include install-includes: nvector/nvector_serial.h when I am issuing cabal install command I am getting the following error: cabal: Error: some packages failed to install: Hydra-0.1 failed during the final install step. The exception was: /home/ggg/.cabal/lib/Hydra-0.1/ghc-6.10.1/include/nvector: copyFile: does not exist (No such file or directory) It seems to me that cabal forgets to create parent directories for folder nested include files. For not-nested include files install-includes filed works fine. The Cabal version I am using is 1.6.0.1. The cabal-install version I am using is 0.6.0 Currently, as a workaround I am using data-files field to install include files. However, I would like to see this issue fixed (I assume it is a bug). Cheers, George -- George Giorgidze http://www.cs.nott.ac.uk/~ggg/

[Hackage] #456: `cabal info pkg` command

#456: `cabal info pkg` command ---------------------------------+------------------------------------------ Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: easy (<4 hours) | Ghcversion: 6.8.3 Platform: | ---------------------------------+------------------------------------------ The output for `cabal list` cannot be too verbose or it looses its purpose as a search. For details on an individual package we could use `cabal info foo` instead. This could present the info for the package in greater detail. For example, most of the meta-data from the .cabal file or installed package info. In particular the bug report url (#449) and the location of any installed documentation (#361). Alternatively we could do this in `cabal list` with some flag to get more detailed information. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/456> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #473: Cabal-1.6 does not work on Windows with ghc-6.6.x

#473: Cabal-1.6 does not work on Windows with ghc-6.6.x ----------------------------------+----------------------------------------- Reporter: duncan | Owner: Type: defect | Status: new Priority: normal | Milestone: Cabal-1.6 Component: Cabal library | Version: 1.6.0.1 Severity: normal | Keywords: Difficulty: very easy (<1 hour) | Ghcversion: 6.6.1 Platform: Windows | ----------------------------------+----------------------------------------- http://haskell.org/pipermail/cabal-devel/2009-January/004622.html The problem is the `writeFileAtomic` function calls the compat version of `openNewBinaryFile` and that fails on Windows with ghc-6.6. Specifically it is the `fdToHandle` that throws the exception. The crux is: {{{ fd <- withCString filepath $ \ f -> c_open f oflags 0o666 h <- fdToHandle (fromIntegral fd) }}} However `fdToHandle` fails with the exception {{{ fdGetMode: invalid argument }}} This is because in ghc-6.6.x, the `fdToHandle` calls `fdGetMode` and passes the result to `openFd`: {{{ fdToHandle :: FD -> IO Handle fdToHandle fd = do mode <- fdGetMode fd let fd_str = "<file descriptor: " ++ show fd ++ ">" openFd fd Nothing False{-XXX!-} fd_str mode True{-bin mode-} }}} However `fdGetMode` is described thusly: {{{ fdGetMode fd = do #if defined(mingw32_HOST_OS) || defined(__MINGW32__) -- XXX: this code is *BROKEN*, _setmode only deals with O_TEXT/O_BINARY }}} Note that the `openBinaryTempFile` function does not call `fdToHandle`, instead it bypasses it and calls `openFd` directly. The `openFd` function is exported from `GHC.Handle` so we could use it in `Distribution.Compat.TempFile` -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/473> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
