[gentoo-user] wxPython/wxWidgets release number mismatch

[Grant Edwards]

Does anybody have any idea what the below is trying to tell me?

_WHAT_ two compenents are mismatched?

WTF is the point of printing a "release number mismatch" warning
without tell the user which two components are mismatched?

You might as well print out

    WARNING: something might or might be wrong!

I've reinstalled wxpython, pygtk, and wxGTK, and it didn't help.

Is this because I have wxpython 3.0.2.0 and wxGTK 3.0.4-r300 and
"3.0.2.0" != "3.0.4-r300"?

Those are the current stable versions of the two packages, and there
are no matching combinations of wxGTK and wxpython versions available
in portage.

What is one supposed to do to avoid that warning everytime one starts
a wxpython app?

I think you need to try this:

revdep-rebuild -L wx_baseu-3.0 -- --ask

I had an issue where Audacity and a few others could not start due to
version mismatches. Got an issue where the ABIs were different. After
running the above command and reinstalling, these apps started working
again.

Calculating dependencies... done!
[ebuild   R    ] x11-libs/wxGTK-3.0.4
[ebuild   R    ] x11-libs/wxGTK-3.0.4-r300

I would presume wxPython will be in your list.

It wants to re-install wxpython-3.0.2.0, wxGTK-3.04 and
wxGTK-304-r300.  I've already done that a few times, but I answered
'y' anyway and let it reinstall them again.  It didn't help:

$ python -c "import wx"

Have a look at bug #639276 in case it is related to your problem:

It needs to be version bumped. https://bugs.gentoo.org/632602

The current version of wxPython is actually 4.0.x and is not compatible
with wxGTK 3.0.4. wxGTK needs to be bumped as well
https://bugs.gentoo.org/577030 but there are some breaking changes in
3.1 vs 3.0.

wxPython 3.0.2.0 is considered 'classic' and was released in 2014.

I tried to use a virtualenv with system package access and tried `pip
install wxpython` but the oldest sane version you can go back to 4.0.3
which won't build with 3.0.4 version of wxGTK.

This discrepancy between the two does not look like it will be fixed any
time soon.

No, that seems to be a different problem with incompatible ABIs.
AFAICT, the ABIs in my case are comptable, and so far, applications
seem to run OK, but I always get the warning.

Sounds like a mess.  The Gentoo stable versions _seem_ to work OK
together at the moment (for the apps I've tried), but the warning
every time you run one doesn't inspire confidence.

That would be enough for me to stop using packages that rely on it. 2014 is a long time ago for any major package like this. I would expect crashes and instability with such apps. If I really need it, I would find another way to get the latest versions of wxPython and wxGTK installed. Maybe an overlay has that set up. Or you can build a local copy of the packages and use them that way.

To my knowledge then that would also mean porting the program to it, as
it's a complete python bindings rewrite. Though the python API might be
quite the same compared to wxpython-3.0.2 with some exceptions and thus
maybe not a huge work.
For Gentoo it is of course quite a bit more "fun" when now all of a
sudden "import wx" could be either wxpython-3 or wxpython-4, even after
you get them installed in parallel in a separate SLOT without file
collisions. And that's why I still haven't even looked at this huge
bunch of needed work and testing. (more people want newer gnome right
now..)

I'm quite sure that is not true - wxPython 4.0.x README says it works
fine with wxWidgets 3.0, or more specifically wxGTK-3.0.4.

And 3.1 is ABI unstable development release, and we distributions
aren't fond of them.
Latest stable wxWidgets is 3.0.4, and we are up to date there with
wxGTK.

It's just a warning from the times wxpython was released more or less
in tandem with wxWidgets. When their wxpython-4 worked progressed far,
they stopped doing that, and that old warning now apparently hits. But
all it is, is a warning. It'd be more of a problem if it ended up using
wxGTK-3.1 or a future 3.2. But wxGTK-3.0.4 is just bug fixes over
3.0.2, plus some new API and tiny careful backwards compatible ABI
changes (via ELF symbol versioning, etc). It should be fine as-is.
There might be value in relaxing that warning with a downstream patch,
but personally I'd rather save that time and work on wxpython-4
instead.

Yes, it'd be nice if we had wxpython-4. Help welcome. Also help welcome
in having wxpython-3 use wxGTK:3.0-gtk3 or have a separate SLOT for
that itself as well.

wxGTK-3.1 however is of debatable value due to development series and
ABI instability combined with a C++ ABI world. Most upstream developers
seem to ship their own wx things static linked into their stuff, so
don't seem to understand the needs of Linux distributions, or just
basic good release management. I am tired of trying to have that
improved by upstream - I've tried for ~14 years now, including while
being an upstream developer myself for wxGTK over a decade ago.

I realize that some programs want to use the new features already, but
we are in the business of building a stable distribution, not throw all
development releases and the caveats from that in front of everyone,
even when manpower is lacking for even the stable versions as-is.

Curiosity: what is the reason for wxGTK:3.0 and wxGTK:3.0-gtk3 ?

wxGTK:3.0 uses gtk+-2 and wxGTK:3.0-gtk3 uses gtk+-3.

That, and we couldn't do it with just flipping it to gtk3 in 3.0 SLOT,
because some wxWidgets apps could be doing conditional direct GTK+ code
as well, to go above the lowest common denominator toolkit support that
wxWidgets provides. Or some might just be wrongly linking directly to
gtk2 explicitly. Or had too much trouble with gtk3 in the less used
parts of wxGTK while wxGTK gtk3 support hadn't quite matured yet.
You can't have a program load in (link to) both gtk2 and gtk3 - it will
abort to not go completely runtime crazy and crash due to same function
names. Kind of like wxWidgets itself aborts if the library and app are
using different C++ ABI (however that's less of a problem with todays
relevant C++ ABI updates, unlike the gcc4 to 5 days).
Therefore it was just a separate parallel installable SLOT with which
we could move things over gradually and have the more maintained apps
benefit before everything is working with it.
