Install to custom prefix
You can install kio-gdrive to your preferred installation prefix,
as long as kdeinit5 has been installed in the same prefix.
Locate Debug Output
You will not see the slave's output in the terminal where you started e.g. Dolphin.
On systemd distros the output will go in the journalctl (assuming Qt built with the -journald option).
A quick way to locate the relevant logs is the following command:
journalctl -b | grep kf5.kio.gdrive
This will only show the logs since the last boot. To retrieve also older logs, you can filter the messages by the process who emitted them (kdeinit5):
journalctl $(which kdeinit5) | grep kf5.kio.gdrive
Enable Debug Output
Th gdrive slave uses categorized debug output. Normally you would enable its output with a simple:
However, you need to make sure this variable is present in the environment of kdeinit5,
which is the process that starts the ioslave.
A simpler alternative is to create (or edit) ~/.config/QtProject/qtlogging.ini with the following content:
