MSYS2-packages: git gui fails with "No working directory ..."

Since the OP didn’t specify the affected version, I’ll add that this issue is still present in package git 2.12.1-1.

Before you get to this error, you will also stumble upon “bitmap “/usr/share/git-gui/lib/git-gui.ico” not defined”. It can be worked around with adding to your ~/.bashrc: export GIT_GUI_LIB_DIR=<msys2_installation_folder>/usr/share/git-gui/lib for instance: export GIT_GUI_LIB_DIR=/c/msys64/usr/share/git-gui/lib and then reloading your bash profile: . ~/.bashrc

(based on https://sourceforge.net/p/msys2/discussion/general/thread/1bf2e8a6/)

A different workaround than downgrading would be to install Git from https://git-for-windows.github.io/ and then add an alias to ~/.bashrc: alias git='/c/Program\ Files/Git/cmd/git.exe' As a benefit you also get a newer version than in Msys2.

Still true in 2.34.1-1 installed with pacman + msys2

Both workarounds mentioned in https://github.com/msys2/MSYS2-packages/issues/801#issuecomment-299442554 still work:

• setting the LIB env-var
• aliasing git to the binary installed from https://gitforwindows.org/
