Hmatrix on Mac OS X
Please update this page with anything you discover along the way.
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.
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.
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 http://dis.um.es/~alberto/GSLHaskell --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
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:
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/
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:
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.
