Here are some notes on getting GSLHaskell running under MacOS X 10.4 using MacPorts. 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.


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 Haskell, 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

As of 20 Jan 2007, the Darcs version of GSLHaskell was easier to get working than the older tarball release. Download it as follows:

{{{ darcs get --partial }}}

Next, edit GSLHaskell/src/GSLHaskell.cabal to refer to the appropriate versions of BLAS and LAPACK:

{{{ extra-libraries: gsl gslcblas LAPACK }}}

To build and install GSLHaskell, type:

{{{ cd GSLHaskell/src runhaskell Setup.hs configure runhaskell Setup.hs build sudo runhaskell Setup.hs 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 GSLHaskell/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.
