wxWidgets broken on macOS BigSur due to XCode 12 issue

[MSoegtropIMC]

wxWidgets is broken on macOS BigSur due to a bug in XCode 12, which apparently has been fixed meanwhile, but the binaries supplied by MacPorts for wxWidgets are faulty.

See: ​https://lists.macports.org/pipermail/macports-users/2020-December/049255.html

The effect of the bug is that /opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/lib contains modified copies of dylib files instead of symlinks. Several wxWidgets apps I tried on BigSur don't start for this reason (wxMaxima, FileZilla e.g.)

Recompiling wxWidgets locally with:

sudo port -f uninstall wxwidgets-3.0
sudo port -v -s install wxwidgets-3.0

fixes this. So in order to fix the wxWidgets port it might be sufficient to just recompile the current versions on the MacPorts servers. If the MacPorts build servers still have the old version of XCode, they need to be updated. The XCode version which has clang-1200.0.32.29 seems to work.

See ticket wxmaxima ticket (#61933) for some discussion and history.

Many thanks @kencu for finding the root cause for this!

P.S.: I tested today on a freshly installed BigSur machine that MacPorts as of today supplies faulty wxWidgets shared libraries.

wxwidgets just needs a revbump, but only Ryan knows if the buildbot has been updated to the newest Xcode which has to be done first.

do this:

sudo port -f uninstall wxwidgets-3.0
sudo port -v -s install wxwidgets-3.0

while it is sorted out if it is time for a revbump, depending on the Xcode installed on the buildbot.

If the commands posted by Ken don't fix it, you need to update XCode.

I've updated both of the macOS 11 worker machines to macOS 11.2.3 and Xcode 12.4, which some claim fixes this issue. I have not verified that.

[kencu (Ken)]

I won't claim anything, but I witnessed this 61933#comment:10 and that is all I know about that.

@mojca -- please consider revbumping wxWidgets-3.0 to (see if it will) fix this issue for everyone plagued by it all these months.

It is a closed maintainer port, but beyond that to be honest it's not really clear to me how to revbump it exactly.

There is some other subport wx-Python that is a near but different version and it says to revbump that as well --- but I can't tell if that means to revbump wx-Python when you're revbumping wxWidgets-3.0.

wxWidgets-3.2: revision bump to fix build on macOS 10.11

Seems the same issue reported for the 3.0 version

Closes: #62491

py-wxpython-4.0: revision bump to fix build on macOS 10.11

Because it uses an internal build of wxWidgets therefore just as
precaution I bump the revision.

Seems the same issue reported for the 3.0 version
#62348

I hope this has been fixed with ​https://github.com/macports/macports-ports/pull/9728

wxPython should generally be left intact unless someone happens to release wxPython 3.0.X in the meantime. It probably needs to be stuck at 3.0.2 "forever", or at least until we have migrated all the wxpython code to Phoenix (version >= 4).
