Haskell for openSUSE

To generate the Haskell OBS repositories for openSUSE Linux, perform the following steps:

1. Clone this repository with the --recursive flag or, alternatively, run

    $ git submodule update --init
   

   in your checked-out copy.

2. Check out the devel:languages:haskell:lts:6 OBS repository and move it to _build/lts-6 by running:

    $ osc co devel:languages:haskell:lts:6
    $ mkdir -p _build
    $ mv devel:languages:haskell:lts:6 _build/lts-6
   

3. Check out the devel:languages:haskell:lts:next OBS repository and move it to _build/nightly by running:

    $ osc co devel:languages:haskell:lts:6
    $ mkdir -p _build
    $ mv devel:languages:haskell:lts:next _build/nightly
   

4. Run cabal update.

5. Run make -j update to download the latest package sets from Stackage.

6. Run make -j to re-generate all spec files. The GNUmakefile included in this repository is just a thin wrapper to start the real build process, which is implemented using shake in the cabal2obs sub-project. You can always run

    $ runhaskell tools/cabal2obs/Main.hs -j$(nproc)
   

   directly if you don't want to be bother with make, but using the make wrapper is usually more convenient.

   Note that the initial run of the build system might take ~10 minutes on reasonably fast hardware. Shake displays an estimated run-time in the title of the X11 window in which the build was run. Once the initial build has succeeded, further re-runs will be very fast.

7. Inspect the build/nightly and build/lts-6 hierarchies with osc status and osc diff to make sure that all generated changes look reasonable. There should be no modifications in any of these projects:

   • build-compare
   • ghc
   • ghc-bootstrap
   • ghc-rpm-macros

8. Commit:

    $ osc ar
    $ osc ar *
    $ osc commit -m "update generated by cabal2obs"
