kompare on Mint 19.1: cannot use/config

[easylm]

Hi
I've installed kompare with:

Code: Select all

sudo update
sudo apt install kompare

but launching it I cannot configure the diff tool to use...
I can add the path to i.e. xxdiff, but kompare doesn't update its config after closing it...

Where does kompare save its configuration on Mint 19.1?
thx

Here's a nice-looking page about setting the kompare "diff" options - you might need to do more stuff before "Compare" isn't grayed out.
https://docs.kde.org/trunk5/en/kdesdk/k ... tings.html

Find Kompare config files:

Code: Select all

find $HOME -iname "*komp*" 

Look for files you don't own (running as root/sudo can 'lock' files for a regular user):

Code: Select all

find $HOME ! -user $USER

Nothing returned = the right answer.

What I've noticed is that if I change i.e. Font Size, even this choice is not saved.
This instead is working with Kate.
