I don't know whether these decisions are correct. I'll trust you. As long as kdebindings works as expected in non-Debian systems _and_ various python bindings work in KDE.

Slackware always uses stock KDE sources from upstream. Thus, if the KDE devs were including sip and python support in kdebindings, Patrick would not monkey with that. NOt saying who is right or wrong, just sharing facts. :)

SIP was not included with the stock Slackware but available as an extra package.
PyQt3 was not included with the stock Slackware but available as an extra package.
PyKDE is unknown to Slackware. By your description, sounds as though this Debian package is the python-specific portion originally packaged with kdebindings.

Sounds as though the first two packages are not strict build prerequisites, but recommended build prerequisites and should be built/installed by people who want those bindings when building pyKDE. Is that correct? Or do users merely install SIP and PyQT after installing KDE and those bindings work thereafter with KDE? There has to be some way when building kdebindings to provide the foundations hooks so python will work with KDE.

How does all of this affect building the core KDE packages? Do I need to modify my kdebindings build script?

With that said, I have progressed further with kdebindings.

I mentioned my scheme to copy on-the-fly in my build script the python/sip/sipgen files from 3.5.10. That gets me past the original build failure. Of course, your information sounds as though all of that will disappear now anyway.

Sounds good.

With that said, my builds go for a while before failing. I have patched some /usr/include files from kdelibs. All of the patches are one-liners adding a specific tqt interface include statement. You can review the patches and decide whether they are necessary. Maybe they are, maybe they are not with the changes you propose.

The process is slow because I get to see only one failure when the build fails. I add an appropriate include statement and then build again. I don't know the QT/TQT interface like you and I have to learn which include statement to add. Takes time. Regardless, the three patches I am including eliminate the build failures related to those files. Good thing this stuff can run in the background. :)

I just compiled again and received an error I don't know how to fix. Log attached.

I don't now how this is all affected by what just shared, but I suspect we are getting closer to building kdebindings. :)
