Hmatrix on Mac OS X

Here are some notes on getting hmatrix running under Mac OS X 10.4 or 10.5 using MacPorts or fink.

These notes may be incomplete or even incorrect, but should point you in the right direction. The latest version of hmatrix considered here is

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. No sure why? 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.

Required libraries

The hmatrix package requires working versions of GSL, BLAS and LAPACK.

You can get GSL and BLAS from DarwinPorts:

sudo port install gsl

LAPACK, however, is already installed on MacOS X 10.4/10.5, namely in the vecLib (10.4) or Accelerate (10.5) frameworks. They appear to work fine with hmatrix, though I didn't test very much.

If you're using the 32-bit Haskell Platform and your MacPorts installation defaults to 64-bit binaries you want MacPorts to build universal binaries of gsl using:

sudo port install gsl +universal

or upgrade after an installation using:

sudo port upgrade --enforce-variants gsl +universal

otherwise you'll get the following error when you try to use hmatrix:

Loading package hmatrix- ... can't load .so/.DLL for: gsl (dlopen(/opt/local/lib/libgsl.dylib, 9):
no suitable image found. Did find: /opt/local/lib/libgsl.dylib: mach-o, but wrong architecture)

Installing hmatrix

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

darcs get --partial

The following steps seem obsolete to me. -- Apfelmus

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

extra-libraries:    gsl gslcblas LAPACK

you might also have to edit cc-options and ld-options to look in your ports directory:

cc-options:         -O4 -I/opt/local/include
ld-options:         -L/opt/local/lib

To build and install the package, type:

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

Using hmatrix

To load hmatrix using GHCI, you need to add the directory containing the gsl shared library to your LD_LIBRARY_PATH:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/local/lib

Mac OS X < 10.10

On Mac OS X 10.4, the LAPACK implementation is contained in the vecLib framework. For interactive use, type

ghci -framework vecLib

To build an example program using GHC, type:

cd examples
ghc --make -framework vecLib plot.hs

Mac OS X >= 10.10

On Mac OS X Yosemite and above, vecLib is now called Accelerate. For interactive use, type

ghci -framework Accelerate

To build an example program using GHC, type:

cd examples
ghc --make -framework Accelerate plot.hs

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.

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 --partial
 (fink instal gnuplot)
 runhaskell Setup.lhs configure
 runhaskell Setup.lhs build
 runhaskell Setup.lhs install
 cd examples
 export LD_LIBRARY_PATH=/sw/lib/
 runhaskell tests
 OK, passed 100 tests.
 OK, passed 100 tests.

Note that the latest version requires cabal 1.2 and the present fink version of ghc (6.6) has lower version. Nevertheless after installing cabal (which itself requires zlib and filepath) hmatrix installs without problems.
