Hmatrix on Mac OS X
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 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
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
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:
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:
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.
