Arch Linux User Repository

The python-setuptools package is pulled in by python-coverage which is pulled in by python-pytest-cov. The python-pytest-cov is in checkdepends, but not makedepends. I think this means makepkg will fail with the --nocheck option. The PKGBUILD guideline wiki (https://wiki.archlinux.org/index.php/Arch_package_guidelines) doesn't cover what to do in this case and namcap is useless for Python packages so I asked in the forums: https://bbs.archlinux.org/viewtopic.php?pid=1962482#p1962482

==> Starting build()...

Missing dependency to python-setuptools?

@selion python-pywavelets is already in depends. I don't know why you get this problem. And also I don't know why you created a deletion request.

I get a module not found error pywt when importing skimage.filters

Installing python-pywavelets fixes that

Build seems to only use a single CPU core and hence is excruciatingly slow. Any chance we could use multiple cores?

No install possible - what is the problem?

I'm getting an error when I try to import skimage.io.

https://hastebin.com/wukepifuxo.sql

I'm getting a conflicting package error when I shouldn't be:

looking for conflicting packages...
:: python-scipy and python-scipy-openblas are in conflict. Remove python-scipy-openblas?

But python-scipy-openblas is listed as sufficient in the Dependencies table. What's going on?

@bertptrs Fine, so I bring back the build() function now. Thanks!

You are right on the prepare() part; I've misread the diff. And while the package builds fine, the problem of compiling in package_*() is more of a semantic one. Some packages (quite a few unfortunately) compile source code in the prepare() phase, but this is incorrect. Most python packages only need to byte-compile all of their .py files. For this package it is especially noticeable as there is a lot of actual native code compilation.

The correct way to do it is: have a build() that calls python(2) setup.py build for both versions, and then in each package_ function call python(2) setup.py install …. The package function really should only be moving files from here to there. Just because you can compile the packages there doesn't mean you should. One might want to inspect the created binaries before creating a package, for example, or really just any use of makepkg --repackage.

You can see an example in the PKGBUILD for numpy: https://git.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packages/python-numpy (and also the previous versions of this package)
