The other day I had a Qt application that needs to access a Futronic FS80 fingerprint scanner. As far as I know this scanner can only be accessed if the program is run as a super user.
Something was fishy in my application, so I decided to debug it running qtcreator via sudo.
Then it became impossible to run qtcreator easily without using sudo, because on startup qtcreator would complain it cannot replace a whole lot of files, like for example
/home/feraudyh/.config/QtProject/qtcreator/devices.xml
It appears that running as sudo has changed the ownership of these files, and I am condemned to reruning qtcreator via sudo, unless I change the file permissions.
I'd like a quick fix to this, I'm not a Linux afficionado.
Would you recommend erasing a whole lot of these files, on the assumption that qtcreator can rebuild them, or should I be less brutal?
Thankyou for your attention.
