[Description Mark Nowiasz 2016-12-31 21:42:01 UTC]

When trying to emerge -uDN @world @system, kde-apps/pykde4-4.14.3-r1 fails with:

Could it be that pykde4-4.14.3-r1 is incompatible with (required by lots of packages) dev-python/sip-4.19?

[Comment 3 Martin von Gagern 2017-01-01 19:49:07 UTC]

I'm seeing something similar, with the difference likely due to a different order of files being processed by this parallel build.

Looking at the SIP documentation of changes for 4.19:
http://pyqt.sourceforge.net/Docs/sip4/incompatibilities.html#sip-v4-19

> Generated Type Structures for Imported Types
>
> As described in Generated Type Structures SIP generates a type
> structure for each C structure, C++ class and namespace, mapped type
> and named enum. Prior to this version every type structure in a
> module was automatically available to any handwritten code in any
> module that imported it.
>
> Starting with this version only those type structures needed by the
> generated code are automatically available to handwritten code
> possibly resulting in compiler errors. Handwritten code should be
> changed to call sipFindType() to obtain a pointer to the required
> type structure.

So I'd say that's the problem here. Perhaps combined with the fact that sipConvertFromNewInstance is deprecated according to
http://pyqt.sourceforge.net/Docs/sip4/c_api.html#c.sipConvertFromNewInstance

[Comment 4 Kelly Price 2017-01-02 15:26:57 UTC]

I have a similar issue, this time involving dev-python/PyQt4-4.11.4-r1, but the relation is dev-python/sip-4.19.  All my info is at https://gist.github.com/STrRedWolf/3f7cd41a611aa10587648dfbcf1babd3 .

[Comment 5 Martin von Gagern 2017-01-02 19:41:28 UTC]

The following sed invocation may help turn all those deprecated combinations of sip…Instance(…, sipClass_…, …) insto sip…Type(…, sipType_…, …).

sed -i -E 's/Instance(.*)sipClass_/Type\1sipType_/' "${S}"/sip/*/*.sip

I've just successfully emerged pykde4, after including the above command into the build process like this:

# mkdir -p /etc/portage/env/kde-apps
# cat >/etc/portage/env/kde-apps/pykde4-4.14.3-r1 <<EOF
post_src_unpack() {
  einfo "Adjusting for sip 4.19"
  sed -i -E 's/Instance(.*)sipClass_/Type\1sipType_/' "${S}"/sip/*/*.sip || die
}
EOF

Unfortunately the ebuild doesn't contain tests, so I don't know whether the code I compiled works as intended. I guess chances are good, though.

So it looks as though we don't need sipFindType after all. Which is a good thing, since I couldn't find out how exactly to format the string argument for this function. There is little documentation, and Google turned up very few examples.

This is caused by mixing stable PyQt4 with testing sip.

I run into the original issue (comment #0) with these packages:
dev-python/PyQt4-4.12
dev-python/sip-4.19
kde-apps/pykde4-4.14.3-r1

My comment #6 was in response to comment #4, which is describing a different issue to the rest of the bug.

[Comment 9 Michael Palimaka (kensington) 2017-01-05 08:33:16 UTC]

By the way, pykde4 is completely unmaintained upstream so we can't count on a proper fix. There are very few revdeps remaining, so it would be interesting to know for which packages people are using to still need pykde4.

[Comment 10 Steven Green 2017-01-05 08:51:57 UTC]

The only package that depends on pykde4 on my machine is kde-apps/kajongg which I've never ever used.

This is a dependency of kdegames-meta (with python use flag) which is a dependency of kde-apps-meta.

[Comment 11 Dan Goodliffe 2017-01-05 08:55:44 UTC]

kde-misc/synaptiks for me. Not aware of any alternatives, but I'd gladly try any suggestions in the spirit of removing some dead wood.

Fortunately a whole lot of changes hit kajongg master including porting away from pykde4, so we should see that in KDE Applications 17.04.

I'm afraid that synaptiks (along with the rest of Plasma 4 and related packages) will be retired soon to kde-sunset.

[Comment 13 Dan Goodliffe 2017-01-05 09:19:49 UTC]

Had a quick search... kde-misc/kcm-touchpad look like it might do the trick. I'll trial it when I get near my laptop and see if it is a [drop-in] replacement.

# q depends -Q pykde4
kde-misc/kanyremote-6.3.5

Turns out you don't need anything like that. I've been using the built in one in KDE for ages and didn't realise it wasn't synaptiks... so that's dead and so is pykde4 for me.

[Comment 16 Roc Vallès 2017-01-07 05:23:15 UTC]

Why not just temporarily remove kajongg from kdegames-meta?

Anyone missing it can install manually, and we can have it back by 17.04.
