hmatrix installation

WARNING: some of these instructions are now very out of date. However, there is a CI script which shows what does work; you are advised to look at that and emulate its installation steps.

Linux

This package requires GHC 7.8, cabal-install (available in the Haskell Platform), and the development packages for BLAS/LAPACK and GSL.

Ubuntu/Debian:

$ sudo apt-get install libgsl0-dev liblapack-dev libatlas-base-dev
$ cabal update
$ cabal install hmatrix-tests

Other distributions may require additional libraries. They can be given in a --configure-option.

Adrian Victor Crisciu has developed an installation method for systems which don't provide shared lapack libraries.

Mac OS/X

GSL must be installed via Homebrew or MacPorts.

Via Homebrew:

$ brew install gsl
$ cabal install hmatrix

Via MacPorts:

$ sudo port install gsl +universal
$ cabal install hmatrix

Windows 10

Stack-based build (preferred)

  1. Install the Haskell Tool Stack tool (stack). How to do that is explained here.

  2. Get, and link to the import library of, the OpenBLAS library. There are various ways to do that. Perhaps the easiest is to use MSYS2 to get it, which is explained in the steps under subheading 2(a) below.

    2(a) Get OpenBLAS library with stack's MSYS2

    1. stack comes with a version of MSYS2. It is located in a subfolder of the folder returned by the stack path --programs command. At the time of writing (9 September 2021), that subfolder is msys2-20200903. Change directory to that folder. In PowerShell:

      > stack path --programs | cd
> cd msys2-20200903

    2. Open a MSYS2 terminal window, with the msys2_shell.cmd command. In PowerShell:

      > .\msys2_shell.cmd

    3. In principle, MSYS2 itself can be updated with the pacman -Syu command. At the time of writing, that may be complicated by keyring issues (see here and here to overcome such issues). In MSYS2:

      $ pacman -Syu

    4. Use MSYS2 to install the OpenBLAS package (and its dependencies). In MSYS2:

      $ pacman -S mingw-w64-x86_64-openblas

      MSYS2 will put the import libraries in subfolder \ming64\lib. The stack enviroment will automatically add that folder to the list of library folders (see, back in PowerShell, the result of command stack path --extra-library-dirs).

    5. hmatrix depends on OpenBLAS. hmatrix-gsl depends on GSL (the GNU Scientific Library) and hmatrix-glpk depends on GLPK (the GNU Linear Programming Kit). You can use MSYS2 to install GSL and GLPK packages too. In MSYS2:

      $ pacman -S mingw-w64-x86_64-gsl
$ pacman -S mingw-w64-x86_64-glpk

      Again, MSYS2 will put the import libraries in subfolder \ming64\lib.

    6. In hmatrix.cabal, ensure that the extra-libraries specifies openblas (only). (This was corrected in hmatrix-0.20.1.) That is, the extract should read:

      if os(windows)
    if flag(openblas)
        extra-libraries: openblas
    else
        extra-libraries: blas lapack

    7. Similarly, in hmatrix-gsl.cabal, ensure that the extra-libraries specifies gsl (only). (This is incorrect in hmatrix-gsl-0.19.0.1 on Hackage, so a corrected local version of the package may be required.) That is, the extract should read:

      if os(windows)
    extra-libraries: gsl

    8. To test, change directory to the repository folder packages\tests, and create a stack.yaml file there, with command stack init.

      Edit the stack.yaml file to refer to the location of a correct hmatrix-gsl.cabal (if the version on Hackage is still incorrect).

      packages:
- .
- ../gsl

      Then stack ghci can be invoked in that folder with an appropriate resolver, and setting the flag openblas for package hmatrix, the flag onlygsl for package hmatrix-gsl and the flag gsl for hmatrix-tests. At the time of writing, resolver lts-18.9 works with GHC 8.10.7. In PowerShell:

      > stack --resolver lts-18.9 ghci --flag hmatrix:openblas --flag hmatrix-gsl:onlygsl --flag hmatrix-tests:gsl

    9. In GHCi, test the Numeric.LinearAlbebra module with the following (the almost successful output has many lines and so is shortened below):

      > Numeric.LinearAlgebra.Tests.runTests 20

------ index
+++ OK, passed 100 tests.
+++ OK, passed 100 tests.
...
+++ OK, passed 100 tests.
------ some unit tests
### Failure in: 9
C:\\\\<path>\\\\hmatrix\\\\packages\\\\tests\\\\src\\Numeric\\LinearAlgebra\\Tests.hs:75
randomGaussian
Cases: 52  Tried: 52  Errors: 0  Failures: 1
*** Exception: ExitFailure 1

      The failure of 'some unit tests' number 9 is discussed here.

    2(b) Build OpenBLAS library from source

    WARNING: these alternative instructions may be out of date.

    1. Download and unzip somewhere OpenBLAS http://www.openblas.net/

    2. In MSYS2 console of Stack, i.e.: C:\Users{User}\AppData\Local\Programs\stack\x86_64-windows\msys2-{version}\msys2_shell.bat

      $ cd /.../OpenBLAS
$ pacman -Sy
$ pacman -S make perl gcc-fortran
$ make clean
$ make
$ make install

    3. Then in normal Windows console for building hmatrix base lib (fill in user name, versions and check if paths are different on your machine):

      > stack install --flag hmatrix:openblas --extra-include-dirs=C:\Users\{User}\AppData\Local\Programs\stack\x86_64-windows\msys2-20150512\opt\OpenBLAS\include --extra-lib-dirs=C:\Users\{User}\AppData\Local\Programs\stack\x86_64-windows\msys2-20150512\opt\OpenBLAS\bin --extra-lib-dirs=C:\Users\{User}\AppData\Local\Programs\stack\x86_64-windows\msys2-20150512\usr\lib\gcc\x86_64-pc-msys\6.3.0\

Cabal-based build

(Not tested). It should be possible to install the new package hmatrix >= 0.16 using the dlls contributed by Gilberto Camara available in gsl-lapack-windows.zip.

  1. cabal update

  2. Download and unzip gsl-lapack-windows.zip into a stable folder %GSL%

3.a) In a msys shell:

$ cabal install hmatrix-0.13.1.0 --extra-lib-dir=${GSL} --extra-include-dirs=${GSL}

3.b) In a normal windows cmd:

 > cabal install --extra-lib-dir=%GSL% --extra-include-dirs=%GSL%

It may be necessary to put the dlls in the search path.

It is expected that a future version of the new hmatrix-gsl package can also be installed using this method.

Alternative Windows build

> cabal update

  1. Download and unzip somewhere OpenBLAS http://www.openblas.net/

  2. In a normal Windows cmd:

    cabal install --flags=openblas --extra-lib-dirs=C:...\OpenBLAS\lib --extra-include-dirs=C:...\OpenBLAS\include

Tests

After installation we can verify that the library works as expected:

$ cabal install hmatrix-tests
$ ghci
> Numeric.LinearAlgebra.Tests.runTests 20
+++ OK, passed 100 tests.
+++ OK, passed 100 tests.
... etc...
+++ OK, passed 100 tests.
------ some unit tests
