Unable to run brew update because of error: Failure while executing: git stash save --include-untracked --quiet

[pk2061]

I am trying to run brew update on my iMac G3 with tiger.

Unfortunately I am getting the following error:

imac-g3:~ jan$ brew update
Stashing your changes:
Error: Failure while executing: git stash save --include-untracked --quiet
imac-g3:~ jan$

I have git 2.48.1 already installed.

Can you please advice me what to do?

Thanks very much!

Can you try running this command from issue #1093 and see if it works?

git config --global --add safe.directory /usr/local

I have tried this, but it just gives me an "Illegal instruction" error:

imac-g3:~ jan$ git config --global --add safe.directory /usr/local
Illegal instruction

@pk2061 Did you build git with GCC 4.2 on Tiger by any chance?

[pk2061]

I guess so.
I just ran „brew update“ and „brew upgrade“ some days ago and git and as also updated back then.

If you look in ~/Library/Logs/Homebrew/git/01.gmake that'll tell you for definite. At the top of the file, a few lines down, was CC set to gcc-4.2?

If so, it seems that git is broken when built with gcc-4.2 on Tiger now, haven't investigated it, but Misty hit the issue a few days ago and added an exclusion.

If you did build with GCC 4.2, brew uninstall git and reinstall, forcing GCC 4.0 by issuing brew install git --cc=gcc-4.0

Thanks for clarifying where to look.

I guess I broke it myself.
In the log of 01.gmake i found CC=/usr/local/bin/gcc-7
I remebered I did some tinkering with the gcc symlink and set that to the wrong gcc version.

I am currently trying to reinstall git and let you know the result!

Thanks for the help & support so far! :)

[pk2061]

Just an update:
I reinstalled git again with brew install git --cc=gcc-4.0 it worked.

Also brew update works again as well!

Thanks again for the help!

Excellent, I'm glad it's resolved!
