[new] python-scipy (+atlas +f2py)

The SciPy-Package adds lots of scientific functions to Python.
It uses some Fortran libraries for some of the complicated algorithms (Fourier transforms, Linear Algebra operations), thus it needs the following depends:

- python (>= 2.2, already available in Pacman)
- python-numeric (already available in Pacman)
- gcc-g77 (already available in Pacman)
- ATLAS libraries (for Linear Algebra operations): you can download binaries and copy them to /usr/lib/atlas OR make the source, I am not skilled enough to provide a PKGBUILD (somebody else?)
- F2PY: easily installed with the following PKGBUILD:

#PKGBUILD F2PY -----------------------
pkgname=F2PY
pkgver=2.45.241_1926
pkgrel=1
pkgdesc="Fortran to Python interface generator"
url="http://cens.ioc.ee/projects/f2py2e/"
license=""
depends=(python>=2.1, python-numeric>=20)
conflicts=()
replaces=()
backup=()
install=
source=(http://cens.ioc.ee/projects/f2py2e/2.x/$pkgname-$pkgver.tar.gz)
md5sums=()

build() {
  cd $startdir/src/$pkgname-$pkgver
  python setup.py build || return 1
  python setup.py install --prefix=/usr --root=$startdir/pkg
}
#-------------------------------------

Finally: SciPy with the following PKGBUILD:

#PKGBUILD SciPy -----------------------
pkgname=python-scipy
pkgver=0.3.2
pkgrel=1
pkgdesc="Scientific tools for Python"
url="http://www.scipy.org"
license=""
depends=(python>=2.2, python-numeric>=21.3, gcc-g77, F2PY)  # this actually also needs ATLAS (see above)
conflicts=()
replaces=()
backup=()
install=
source=(http://www.scipy.org/download/scipy/src/SciPy_complete-$pkgver.tar.gz)
md5sums=()

build() {
  cd $startdir/src/SciPy_complete-0.3.2
  python setup.py build || return 1
  python setup.py install --prefix=/usr --root=$startdir/pkg
}
#----------------------------------------

Any comments?

Re: [new] python-scipy (+atlas +f2py)

hmmm.
looks like i've just spent some time doing what has already been done.

well, i searched in AUR+pacman and since i couldn't find anything like scipy, i made a package myself. the reason is that i also made complete ATLAS+LAPACK package which is available in AUR and i wanted to test it somewhere besides in my own programs.

@hugelmopf: i am sorry that i put my scipy packages to AUR, you may adopt them if you want.

Re: [new] python-scipy (+atlas +f2py)

No worries at all. Please keep your packages and maintain them, because due to my new AMD64 processor I am not using Archlinux right now (wanted to try the Debian Pure64 port ;-))

That is also the reason, that these Pkgbuilds are not in the AUR, sorry. And I don't even know, if they work anymore...

So good luck with your packages,
Frank
