In Linux, my favorite merge tool is Meld, and I\'ve had no problems using or configuring it to work with Git. However, in Windows it has been a different story.

None of the answers worked for me. I ended up with this in the .gitconfig-file:
[merge]
tool = meld
[mergetool "meld"]
cmd = 'C:/Program Files (x86)/Meld/Meld.exe' $LOCAL $BASE $REMOTE --output=$MERGED
[mergetool]
prompt = false
After a git merge mybranch ending with conflicts, you simply type git mergetool and meld opens. After a save, you have to commit in git and the conflicts are resolved.
For some reason, this only worked with Meld 3.18.x, Meld 3.20.x gives me an error.
