Mac升级至10.13.4后运行tkeclipse/tktools出现Objective-C垃圾回收报错

This error happens because macOS High Sierra (10.13+) dropped support for Objective-C garbage collection, but the bundled Wish 8.5 binary in your tkeclipse/tktools setup still relies on this deprecated feature. Here are practical solutions to resolve it:

Solution 1: Patch the Wish startup script to disable GC #

The fastest workaround is to force-disable garbage collection for the Wish binary using an environment variable. Here's how:

1. Locate the wish8.5 script from your error log: /.../Eclipse/tcltk/x86_64_macosx/bin/wish8.5
2. Open it in a text editor (like nano or TextEdit)
3. Modify the final line of the script from:

   "$(dirname $0)/../Library/Frameworks/Tk.framework/Versions/8.5/Resources/Wish.app/Contents/MacOS/Wish" "$@"
   

   To:

   OBJC_DISABLE_GC=YES "$(dirname $0)/../Library/Frameworks/Tk.framework/Versions/8.5/Resources/Wish.app/Contents/MacOS/Wish" "$@"
   

4. Save the file and try running tkeclipse/tktools again. This flag tells the binary to skip GC initialization, which usually fixes the abort trap.

Solution 2: Replace the bundled Tk with a GC-free version #

If the first fix doesn't work, swap the outdated Tk framework with a version that doesn't depend on garbage collection:

• Option A: Use Homebrew to install a modern Tk
  1. Install Homebrew if you haven't already, then run:

     brew install tk
     

  2. Locate the new Wish.app path (typically something like /usr/local/Cellar/tk/8.6.x/Frameworks/Tk.framework/Versions/8.6/Resources/Wish.app)
  3. Update the wish8.5 script to point to this new path instead of the bundled one.
• Option B: Compile Tk 8.5 without GC support
  1. Download the Tk 8.5 source code from the official Tcl/Tk project
  2. Compile it with the --disable-gc flag:

     ./configure --with-tcl=/path/to/your/tcl/source --enable-aqua --disable-gc
     make && make install
     

  3. Replace the bundled Tk.framework in your Eclipse/tcltk directory with the newly compiled version.

Solution 3: Check for tool updates #

If the tool has an official update, it might already include a patched Tk binary compatible with High Sierra. Check the developer's release notes or download page for a version built for macOS 10.13+.

Always back up the original files before making modifications, so you can revert if something goes wrong.
