A lot of Python packages use the setuptools or distutils framework. This mean that the build() and the package() section looks a bit different compared to an application which uses make.
pkgname="py3-foo" ... depends="python3" makedepends="python3-dev" ... build() { cd "$builddir" python3 setup.py build } package() { cd "$builddir" python3 setup.py install --prefix=/usr --root="$pkgdir" }
If Python package support both Python 2 and Python 3, then the Alpine package should provide both variants as py2- and py3- subpackages.
pkgname="py-foo" _pkgname="PyFoo" ... arch="noarch" depends="py-bar" makedepends="python2-dev python3-dev" subpackages="py2-${pkgname#py-}:_py2 py3-${pkgname#py-}:_py3" ... build() { cd "$builddir" python2 setup.py build || return 1 python3 setup.py build || return 1 } package() { mkdir -p "$pkgdir" } _py2() { replaces="$pkgname" depends="${depends//py-/py2-}" _py python2 } _py3() { depends="${depends//py-/py3-}" _py python3 } _py() { local python="$1" pkgdesc="$pkgdesc (for $python)" depends="$depends $python" install_if="$pkgname=$pkgver-r$pkgrel $python" cd "$builddir" $python setup.py install --prefix=/usr --root="$subpkgdir" }
- If the package doesn’t have any dependencies, then omit depends="" in the _py2() and _py3() functions.
- If the package contains some compiled code (native extensions), then replace the subpackages= line with:
subpackages="py2-${pkgname#py-}:_py2:all py3-${pkgname#py-}:_py3:all"
