I’m sort of reviving this thread, because I’ve stumbled upon discussions
around this recently, and in fact I see one practical reason of doing
the build in the package() function rather than in the build() one:
– split python2-lib/python-lib package without build() function (only
the relevant parts):
package_python-lib() {
python setup.py install --prefix=/usr --root="$pkgdir" --optimize=1
}
package_python2-lib(){
python2 setup.py install --prefix=/usr --root="$pkgdir" --optimize=1
}
– vs with build() function:
prepare() {
cp -a libname{,-py2}
}
build() {
cd libname
python setup.py build
cd libname-py2
python2 setup.py build
}
package_python-lib() {
python setup.py install --prefix=/usr --root="$pkgdir" --optimize=1
--skip-build
}
package_python2-lib(){
python2 setup.py install --prefix=/usr --root="$pkgdir" --optimize=1
--skip-build
}
Now, whether this is a good practice or not and what may be the
implications regarding makepkg, that’s a different thing. But it would
be good to agree on one way or another, and keep it the same everywhere
for consistency. If they are good reason to do it the second way, I’d
like to know them. Else, I have a tendency to find the shortest one to
be the best. ;)
