error: git-gui died of signal 6

Does anybody have the same problem and a solution for this?

Answer 1

Try: git config --local --unset gui.geometry
This error occurs due to Tk Geometry manager does not work, due to older version or if it is corrupt.

If the above command didn't work try updating your xcode: xcode-select --install

Answer 2

Instead of using the default MacOS tcl-tk, use the latest tcl-tk(8.6.6) from Homebrew and then link it by force, for example:

brew install tcl-tk
brew link tcl-tk --force

Answer 3

There is a problem with Tk 8.5 on MacOS Sierra. You could replace Tk Wish 8.5 with Tk Wish 8.4

cp /System/Library/Frameworks/Tk.framework/Versions/8.4/Resources/Wish.app/Contents/MacOS/Wish /usr/local/Cellar/git/2.10.1/share/git-gui/lib/Git\ Gui.app/Contents/MacOS/

source: https://github.com/git/git-scm.com/issues/853

UPD: Pay attention to replace the git version in the cp path with your current version

Answer 4

My solution, should work for the git download from https://git-scm.com/

brew install homebrew/dupes/tcl-tk

cd to /usr/local/git/share/git-gui/lib/Git Gui.app/Contents/MacOS and backup the original Wish

cp /usr/local/Cellar/tcl-tk/8.6.6/bin/wish8.6 /usr/local/git/share/git-gui/lib/Git Gui.app/Contents/MacOS/Wish

Answer 5

I conglomerated a bunch of answers from here together, since I am using GIT and TCL via brew:

1. cd "/usr/local/Cellar/git/2.10.2/share/git-gui/lib/Git Gui.app/Contents/MacOS"
2. mv Wish Wish.bkp
3. ln -vs /usr/local/Cellar/tcl-tk/8.6.6/bin/wish8.6 Wish

Over time obviously the version numbers may vary

Answer 6

I consider the following goals to constitute the full solution to the problem:

• "Nuke from orbit" certainty in solving this in a neat and linear fashion

• Do not end up with ugly fonts from a legacy Apple Tcl/Tk

• Decouple your git gui from the Apple shipped Tcl/Tk

  • Rely on Homebrew for your Tcl/Tk installation

Below you will find a step-by-step to achieve this:

1. Get the duplicated Tcl/Tk from Homebrew

   brew install tcl-tk
   

2. Add the non-broken Tcl/Tk installation to the path(s) before the broken Apple implementation

   • This assumes your Homebrew paths take precedence over your system paths
   • This should be the case in a normal Homebrew installation
   • This will fail if you have conflicting files from your other installed homebrew recipes
   • For example the_platinum_searcher provides pt, which conflicts

   • I recommend ripgrep for getting around this case

     brew link --force tcl-tk
     

3. Fix your gitk installation by reinstalling against the nonbroken Homebrew version

   • This might not be necessary, but ref. the first stated goal above

     brew reinstall git
     

4. Copy the new wish binary from your Homebrew Tcl/Tk installation over the broken bundled one from Apple in the Git Gui.app bundle

   • This blindly relies on the ouput of homebrew info <package> to not change

     cp "$(which wish)" "$(brew info git | grep Cellar | cut -d' ' -f1)/share/git-gui/lib/Git Gui.app/Contents/MacOS/Wish"
     

The last bit might be wise to slap into an alias into your ~/.bashrc and/or equivalent as it'll have to be repeated every time you get a new git version from Homebrew.

alias fix-gitgui='cp "$(which wish)" "$(brew info git | grep Cellar | cut -d" " -f1)/share/git-gui/lib/Git Gui.app/Contents/MacOS/Wish"'

I am not fully certain why the quoting for the field delimiter character for cut used above works so use this alias with caution as this might very well depend on an exact bash version.

Answer 7

Upgrading to macOS 10.12.2 fixes the problem.

No insight into why from Apple change log: https://support.apple.com/en-us/HT207307.

Answer 8

It works for me: download and install the latest version of TCL (I used 8.6.4) http://www.activestate.com/activetcl/downloads

I also downloaded and installed the latest version (2.10.1) of git https://git-scm.com/

Check that gitk window does not crash after the resizing.

Answer 9

@sbondaryev's answer (39966704) didn't work for me and I've yet to try @ssahu's (40119030). However the trick I describe here crashed far less often (10% of time or so) for me. And it keeps me from messing around too much with things - hopefully the problem will be fixed properly soon.

• Crashing seemed to happen when resizing the window (90% of time). But I found it too small to work with and wanted to resize it.
• vi .git/config
• edit the GUI geography to create a window size that works. I still kept it small though i suspect there will be a size over which crashing will always happen

Answer 10

My Sierra (upgraded from 10.11.6) has Tcl/Tk Current pointing to 8.5 and I observed the same error after the upgrade, with our Python program using Tkinter. I'm not using Wish. I had no help from Python 2.7 32bit installation linked to Tcl/Tk 8.4 as that one did not have "tile". So I brewed my Python, linking it with Tcl/Tk 8.6:

This is for brew to use precompiled bottles instead of building from sources, unless specifically instructed otherwise, so not really causing the issue:

xcode-select --install

Then install Tcl/Tk:

brew install homebrew/dupes/tcl-tk

If you did not install Python originally with --with-tcl-tk, then:

brew uninstall python

Finally:

brew install python --with-tcl-tk

After this I have Python that is linked to Tcl/Tk 8.6 and looks like I got rid of the error.

Answer 11

After a lot of struggles this solution solves my problem:

$ brew upgrade tcl-tk

If it's up-to-date and this does not work, try:

$ brew uninstall tcl-tk
$ brew install tcl-tk

I have tried every solution in the web but only this solves the problem. Cheers!

Answer 12

This has been resolved on the most recent patches to macOS Sierra (10.12.2 and above) and no further action is necessary.

Answer 13

On High Sierra (10.13) I had the same issue with git gui.

I have solved the issue by updating git from 2.7.0 to 2.14.2

brew upgrade git

Answer 14

A fix that worked for me: disconnect second monitor, open git gui -> works, close it, reconnect the second monitor and run git gui -> works again :)
