Help creating a python-wxpython-git package

I have been having problems with the advanced splash part of the python-wxpython package that I think are fixed with this unreleased upstream commit. The python-wxpython-dev AUR package  does not contain the commit and the orphaned wxpython-phoenix-git AUR package is hopelessly out of date. The python-wxpython-dev PKGBUILD looked simple enough that I figured I would give making a new git package a shot. I changed the source location, added a pkgver function and added the git package as a make dependency. The first error I got was related to missing the attrdict module. I got around that by installing the python-attrdict AUR package  with a slight hack related to issues with the collections module:

sed -i 's/collections/collections.abc/g' attrdict/*.py

I then ran into an issue with sip modules. I added the python-sip4 package, but in a clean chroot I still get

==> Starting build()...
Traceback (most recent call last):
  File "/build/python-wxpython-git/src/Phoenix/build.py", line 49, in <module>
    from buildtools.wxpysip import sip_runner
  File "/build/python-wxpython-git/src/Phoenix/buildtools/wxpysip.py", line 20, in <module>
    from sipbuild.code_generator import (set_globals, parse, generateCode,
ModuleNotFoundError: No module named 'sipbuild'

which I think is misleading and is really about the parse module. This might be related to a recent bug in the Debian package but the wxpython folks might have a fix for it, but I cannot tell.

Any ideas how I can proceed?

Re: Help creating a python-wxpython-git package

I think you are right in the cause but your PKGBUILD uses python-sip4 which is no longer supported since https://github.com/wxWidgets/Phoenix/co … f395a7c8a8 there is no sip5 in the repos and sip6 as you have found is broken since 6.6.1 https://github.com/wxWidgets/Phoenix/issues/2169 for which the fix is still being developed.

The python-sip4 PKGBUILD doesn't look too bad. Do you think making a python-sip5 package is the way to go?

Until sip6 support is fixed it is probably the only way to get the package to build.  https://www.riverbankcomputing.com/pipe … 44698.html shows still issues with developing the sip6 fix.
Last version of the sip5 PKGBUILD https://github.com/archlinux/svntogit-p … k/PKGBUILD

Re: Help creating a python-wxpython-git package

Thanks for the help. Hopefully the last question. I feel like I should add

provides=('sip' 'python-sip')
conflicts=('sip' 'sip4' 'python-sip4')

but the sip4 package does not have any such conflicts even though it has the same file names as the sip package.

Re: Help creating a python-wxpython-git package

sip4 has replaces=('sip<5') , python-sip4 has replaces=(python-sip) .
For packages from binary repos that works great, but it's not suitable for aur packages.

I don't know if there's a general rule for provides/conflicts , but for VCS packages best practice is :

provide / conflict with the repo package without a version in the name .

example
Aur has openscenegraph-git and openscenegraph-openmw-git
both provide/conflict openscenegraph but not eachother.
This ensures only one of the 3 versions around will be present.

I suggest you do the same and have sip5 provide/conflict sip while python-sip5 should provide/conflict python-sip  .
