Hi Alan
I think I have fixed it. In fact it turned out that test-drv-info was
doing exactly what it should.
running ldd on the wxwidgets.so file revealed 3 dependencies that
could not be found.
The flavour of Linux I am building on is Arch,
which maintains rolling upgrades of all packages rather than fixed
update releases. Since the last wxWidgets release on Arch, the three
dependencies had all upgraded with new ABIs. I built wxWidgets from
source and now everything is working as it should.
Hi Phil:
I am glad to hear you have apparently solved this library inconsistency
problem.
Debian Testing = Buster and MinGW-w64/MSYS2 are also examples of
rolling releases. For all of those and assuming there was no
packaging error (e.g.,, a mistatement of dependencies), a distribution
update should only update dependencies if system libraries and
executables (e.g., from wxwidgets) were updated in a consistent way
with those dependencies. I have been using Debian for almost two
decades now, and in that time I have never noticed any such
inconsistency issue, and I suspect such issues are rare for the
ArchLinux as well since it has such a good reputation. So perhaps the
ArchLinux system version of wxwidgets was fine with the updated
dependencies, and the trouble was only with your own built version of
wxwidgets?
From Arjen's experience with MinGW-w64/MSYS2, that is one distribution
where you should expect some inconsistency issues. The problem is the
developers of that distribution have a very small team with limited
resources, and they appear not to realize how smooth the user
experience should be with rolling releases. I assume that is because
they don't realize Debian and other Linux distributions have set such
a high standard for rolling releases. My hope is the MinGW-w64/MSYS2
development team will soon figure it out so that distribution becomes
as smooth as the other high-quality rolling releases.
