SDL under ghc 7.8.2

[tbelaire]

It requires a slight fix, if anyone else encounters a problem installing with a recent ghc, here's how I fixed that problem.

File structure is something like

haskanoid-root/
|-> cabal.sandbox.config
\-> haskanoid/
      |->haskanoid.cabal
          .....

From haskanoid-root, (where you ran cabal sandbox init, also do cabal sdl unpack, to get something like:

haskanoid-root/
|-> cabal.sandbox.config
|-> SDL-0.6.5
\-> haskanoid/
      |->haskanoid.cabal
          .....

And edit Graphics/UI/SDL/Events.hsc line 56 to just be import Data.Typeable instead of being very selective in it's imports. Now you can cabal install from the SDL directory to get that dependency fixed.
You'll also need to bump up the base==4.6.* requirement in haskanoid.cabal`.

Thanks!

It might be a good thing to open a ticket on SDL itself, since the typeable thing is their responsibility.

There's two pending tasks here: modify the readme to reflect these instructions, and change the cabal file.

[tbelaire]

I've fired the maintainer of SDL an email, since that's all I saw on Hackage.

Once a new SDL version is out, it'll be easy enough to bump version bounds to get haskanoid to compile, without needing any fancy instructions.

I just followed @tbelaire's instructions and doing cabal install from where SDL is located resulted in installing to my system's cabal folder ~/.cabal. I fixed this by doing cabal sandbox add-source SDL-0.6.5 from haskanoid-root, which is actually just the git clone directory of haskanoid (this is because trying it from the hackage version resulted in the game not starting due to missing data files, giving the error message Some resources could not be loaded).

The instructions don't mention downloading SDL but the project doesn't seem to include it. Should I just download the latest version of sdl and copy it into the project directory?

[tbelaire]

cabal sdl unpack downloads the source code.

[Jks15063]

When I run cabal sdl unpack it replies: cabal: unrecognised command: sdl (try --help)

[tbelaire]

Err, I think I mean cabal unpack sdl, sorry.

OK, cabal unpack sdl works and I now see a SDL dir. However, after editing the Graphics file per your instructions and running cabal install in the root SDL dir, I see this error:

I looked in the README in the SDL dir and tried running runhaskell Setup.lhs configure and received an almost identical error message.

Am I way off?

[tbelaire]

the Haskell sdl bindings require SDL to have been installed, as they are just translations to the C calls to the library.

ok, getting real close. Got sdl installed and then ran into a bunch of missing dev libs so worked my way down the list installing them like this: sudo apt-get install libghc-foo-dev which worked for every except the wii lib. I ran sudo apt-get install libghc-hcwiid-dev which executed succesfully, but I still get this error:

setup-Simple-Cabal-1.21.1.0-x86_64-linux-ghc-7.8.3: Missing dependencies on
foreign libraries:
* Missing (or bad) header file: cwiid.h
* Missing C libraries: bluetooth, cwiid
This problem can usually be solved by installing the system packages that
provide these libraries (you may need the "-dev" versions). If the libraries
are already installed but in a non-standard location then you can use the
flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are.
If the header file does exist, it may contain errors that are caught by the C
compiler at the preprocessing stage. In this case you can re-run configure
with the verbosity flag -v3 to see the error messages.
cabal: Error: some packages failed to install:
hcwiid-0.0.5 failed during the configure step. The exception was:
ExitFailure 1

Is there a lib I'm still missing or a way to ignore the wii libs, I'm not trying to use a wii-mote anyway.
Sorry for all the questions and thanks for all the help already.

You don't want to mix installing Haskell packages and cabal packages I
don't think (someone correct me if I'm wrong).

I typically use apt-get build-dep on Haskell packages that require external
dependencies such as SDL.

When I get to a computer I'll post a command line log of installing
haskanoid on vanilla Ubuntu.

That sounds great, thanks. Should I remove all of the libghc-... packages I installed?

[codygman]

That's what I would do, then again I don't know if any of your other
software packages/projects/workflows would be broken by that.

I think I only have that separation because I'm paranoid about cabal being
able to find apt installed ghc libraries.

I'm getting the same issue as @Jks15063

* Missing (or bad) header file: cwiid.h
* Missing C libraries: bluetooth, cwiid

Did anyone come up with a workaround for this? Running on ubuntu-14.04.1-desktop-amd64.

[ivanperez-keera]

I suspect the problem is that this game uses a new version of hcwiid that was released with accelerometer support, specifically for this game. That version is the lastest one available on hackage. It may already be available in some debian-like distributions like ubuntu, but I don't know if 14.04 has the latest version. If not, then installing haskanoid will try to fetch the latest from hackage, and will need the bluetooth and cwiid development libraries, which are not pulled by libghc-hcwiid-dev (only the binaries are installed, not the headers).

If the above is correct, you need to install libcwiid-dev with apt-get/aptitude, and then hcwiid directly from hackage. The latter should happen automatically when you run "cabal install haskanoid".

Does that work?

[sphvn]

Cheers. Up and running, without having to unpack and modify SDL also.

[sunwukonga]

On my system (archlinux), in addition to unpacking and fixing the Data.Typeable import in Event.hsc, I had missing libraries for both the SDL_ttf and SDL_mixer dependencies.

The readme's of both packages mentioned the required library dependency and I installed with pacman.

pacman -S sdl_ttf sdl_mixer

Haskanoid compiled and ran fine after that.

[ivanperez-keera]

So, I just ran cabal install --only-dependencies with ghc 7.8.4 and ghc 7.10.3 and SDL compiled just fine. Is the installation of SDL still problematic on your machines?

What else do you think should be modified in the README.md file to make the installation instructions clear? Do we need to link to some manual that explains how to install the SDL bindings, SDL libraries or wiimote/kinect libraries?

[ivanperez-keera]

This issue has been frozen for some time. I'm going to close it, since it compiles fine on travis. If you think the instructions are insufficient, then please re-open or, better, send a pull request for a modified README.md!

I'd love to get contributions :)
