[issue42480] Python Tkinter crashes on macOS 11.1 beta

Ned Deily added the comment: @fxcoudert: If you are trying to link with the Apple-provided system Tcl and Tk frameworks, don't. They have been seriously broken since macOS 10.7 and stuck at Tk 8.5.9. The only visible Apple action has been to deprecate them. Any Python on macOS that claims

[issue42480] Python Tkinter crashes on macOS 11.1 beta

FX Coudert added the comment: Hi, Homebrew developer here, we're seeing this with macOS 11.1 and I think it's not a python issue but an Apple's Tcl/Tk issue. The backtrace I have is: 0 libsystem_kernel.dylib 0x7fff2031f462 __pthread_kill + 10 1 libsystem_pthread.dylib

Christopher Snowhill added the comment: That command also crashes with the same error. And I already verified with otool -L on the tkinter shared object file that it does indeed link the /System/Library/Frameworks version of both Tcl and Tk. In fact, if I remember correctly, Homebrew's

[issue42480] Python Tkinter crashes on macOS 11.1 beta

Ned Deily added the comment: If Homebrew links against the Apple-supplied Tcl and Tk frameworks, which are in /System/Library/Frameworks, all bets are off as those are deprecated and hopelessly out-of-date versions of Tcl/Tk 8.5. If tkinter is linked to Tcl and Tk frameworks in

Christopher Snowhill added the comment: Sorry about that. I didn't know that Big Sur support wasn't added until post-3.9.0. I'll check if Brew has a newer version now, and even if not, if I can install a Git version for testing. Incidentally, the error is occuring inside either the Tk or

Ned Deily added the comment: I've installed the 11.1 beta (of 2020-11-17) on an Intel-64 virtual machine and installed and run the test suite for the recently released 3.9.1rc1 Universal2 binaries from python.org. The tests, including tkinter tests, run similarly to how they do on 11.0.1.

Christopher Snowhill added the comment: And I can't report it to Homebrew, either, since they refuse to acknowledge bug reports against beta versions of the OS. I guess I can bug them when 11.1 becomes a stable release, by which time I'll probably be on 11.2. I'll file Feedback with Apple,

Ronald Oussoren added the comment: Note that a python installation created using Mac/BuildScript/build-instalelr.py works fine on macOS 11.0 (I haven't tested on 11.1 beta yet). This may be a problem with homebrew or the way it builds Python and/or Tcl/Tk. --

[issue42480] Python Tkinter crashes on macOS 11.1 beta

New submission from Christopher Snowhill : The Tkinter module, in a freshly built copy of Python 3.9 built by Brew, using the latest Xcode 12.3 command line tools, crashes on Big Sur 11.1 beta. It emits the following error: macOS 11 or later required ! I believe I recently read on macOS
