1# [hmatrix][hmatrix2] installation
2
3This package requires the [Glasgow Haskell Compiler](http://www.haskell.org/ghc/index.html) ghc >= 6.10, and [cabal-install](http://www.haskell.org/haskellwiki/Cabal-Install), conveniently available in the [Haskell Platform](http://hackage.haskell.org/platform), and the development packages for [GSL](http://www.gnu.org/software/gsl) and BLAS/[LAPACK](http://www.netlib.org/lapack). (The graphical functions also require **gnuplot** and **imagemagick**.)

9## Linux ##################################################
10
11
12Ubuntu/Debian:
13
14 $ sudo apt-get install libgsl0-dev liblapack-dev
15 $ cabal install hmatrix
16
17Arch Linux: If the automatic installation from Hackage fails, install atlas-lapack and gsl, unpack the source, change the build-type to Simple in hmatrix.cabal (line 28) and add extra-libraries: gsl lapack (line 194).
18
19Other distributions may require additional libraries. They can be given in a **--configure-option**.
20
21## Mac OS/X ###############################################
22
23
24GSL must be installed via Homebrew or MacPorts.
25
26Via Homebrew:
27
28 $ brew install gsl
29 $ cabal install hmatrix
30
31Via MacPorts:
32
33 $ sudo port install gsl +universal
34 $ cabal install hmatrix

38## Windows ###############################################
39
40We use this [GSL binary](http://www.miscdebris.net/blog/2009/04/20/mingw-345-binaries-of-gnu-scientific-library-112-for-use-with-mingw-and-visual-c/), and blas/lapack dlls built with g77 (contributed by Gilberto Camara). All required files are in [gsl-lapack-windows.zip][winpack].
41
42(Due to [issue 21](https://github.com/albertoruiz/hmatrix/issues/21) we need hmatrix-0.13.1.0.)
43
441) Install the Haskell Platform (tested on 2011.2.0.1)
45
46 > cabal update
47
482) Download and unzip the following file into a stable folder %GSL%
49
50 http://perception.inf.um.es/hmatrix/gsl-lapack-windows.zip
51
523.a) In a msys shell the installation should be fully automatic:
53
54 $ cabal install hmatrix-0.13.1.0 --extra-lib-dir=${GSL} --extra-include-dir=${GSL}
55
563.b) Alternatively, in a normal windows cmd:
57
58 > cabal unpack hmatrix-0.13.1.0
59
60 Edit hmatrix.cabal, in line 28 change build-type to "Simple", and then
61
62 > cabal install --extra-lib-dir=%GSL% --extra-include-dir=%GSL%
63
64 It may be necessary to put the dlls in the search path.
65
66
67NOTE: The examples using graphics do not yet work in windows.

74## Tests ###############################################
75
76After installation we must verify that the library works as expected:
77
78 $ cabal install hmatrix-tests --enable-tests
79 $ ghci
80 > Numeric.LinearAlgebra.Tests.runTests 20
81 OK, passed 100 tests.
82 OK, passed 100 tests.
83 ... etc...
84
85If you get any failure please run lapack's own tests to confirm that your version is not broken. For instance, in ubuntu 9.04, **libatlas-sse2** does not work (see this [bug report](https://bugs.launchpad.net/ubuntu/+source/atlas/+bug/368478)). If your lapack library is ok but hmatrix's tests fail please send a bug report!
86
87
88## Optimized BLAS/LAPACK ##########################################
89
90I have successfully tested ATLAS and MKL on Linux.
91
92### [ATLAS](http://math-atlas.sourceforge.net/) ####################
93
94In Ubuntu >= 9.04 we need:
95
96 $ sudo apt-get install libatlas-base-dev
97
98In older Ubuntu/Debian versions we needed:
99
100 $ sudo apt-get install refblas3-dev lapack3-dev atlas3-base-dev
101
102We may use a version (sse2, 3dnow, etc.) optimized for the machine.
103
104### Intel's MKL ###############################################
105
106There is a free noncommercial download available from Intel's website. To use it I have added the following lines in my .bashrc configuration file:
107
108 export LD_LIBRARY_PATH=/path/to/mkl/lib/arch
109 export LIBRARY_PATH=/path/to/mkl/lib/arch
110
111where arch = 32 or em64t.
112
113The library must be installed with the -fmkl flag:
114
115 $ cabal install hmatrix -fmkl
116
