Here are some notes on getting GSLHaskell running under Mac OS X 10.4 using MacPorts or fink. These notes may be incomplete, and the details may change slightly in the future.

Please update this page with anything you discover along the way.

Contents

1 Installing GHC using MacPorts

First, you will want to install GHC using MacPorts, not the standalone installers. Assuming that you have uninstalled any other versions of ghc, type:

sudo port install ghc

This may take several hours to bootstrap on a slow machine.

2 Required libraries

GSLHaskell requires working versions of GSL, BLAS and LAPACK. You can get GSL and BLAS from DarwinPorts:

sudo port install gsl

The accelerated version of LAPACK bundled with MacOS X 10.4 appears to link with GSLHaskell, though I haven't tested it extensively.

3 Installing GSLHaskell

The most recent version of GSLHaskell is available on HackageDB with the name hmatrix. You can also download it from the darcs repository as follows:

darcs get http://perception.inf.um.es/~aruiz/darcs/hmatrix --partial

Next, edit hmatrix.cabal to refer to the appropriate versions of BLAS and LAPACK:

extra-libraries:    gsl gslcblas LAPACK

To build and install the package, type:

runhaskell Setup.lhs configure
runhaskell Setup.lhs build
sudo runhaskell Setup.lhs install

4 Using GSLHaskell

These instructions are awkward, and can probably be improved with better knowledge of GHC and/or Cabal.

To load GSLHaskell using GHCI, you need to add two directories to your LD_LIBRARY_PATH:

export LD_LIBRARY_PATH=/System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/:/opt/local/lib

To build an example program using GHC, type:

cd examples
ghc --make -optl-L/System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/ plot.hs

5 Plotting with gnuplot and Aquaterm

Install gnuplot using MacPorts:

sudo port install gnuplot

If Aquaterm fails to compile, upgrade to the latest version of XCode. Tell gnuplot what terminal to use:

export GNUTERM=aqua

You should now be able to build and run examples/plot.hs, and see three nicely anti-aliased plots. If you're using an xterm, you can also choose to leave GNUTERM unset to use gnuplot's built-in X11 support, which is uglier, but apparently allows rotation of 3D plots using the mouse.

6 Using fink

With minor changes the instructions work for fink. (I have already had the ghc and ghc-bin packages) In short:

 fink install gsl
 fink install atlas
 fink install darcs
 darcs get http://perception.inf.um.es/~aruiz/darcs/hmatrix --partial
 (fink instal gnuplot)
 runhaskell Setup.lhs configure
 runhaskell Setup.lhs build
 su
 runhaskell Setup.lhs install
 exit  
 cd examples
 export LD_LIBRARY_PATH=/sw/lib/
 runhaskell tests
 OK, passed 100 tests.
 OK, passed 100 tests.
 etc.
