After upgrade tp ver. 5.1.10 cannot place symbol as it errs (the env. vaiable is to be any user’s specific) ${KICAD_SYMBOL_DIR}/4xxx.lib can not found
then if pick don’t show and go on trying for transistor not avaiable,
if pick ‘Select with browser’,
Then in the left pane, an item ‘Transistor BJT’ is ready but nothing if it’s clicked
From what I can see you have a problem with the library setup.
That KiCad complains it can not find the 4xxx.lib library at least means that KiCad is looking for it. This means that library is mentioned in the sym-lib-table file, and that is a good thing.
Which leaves two obvious possibilities. Either the ${KICAD_SYMBOL_DIR} environment variable is set to the wrong path (You can check this with KiCad / Preferences / Configure Paths) or the libraries themselves are not present at all.
So first check if that library is present at your computer, on my linux box I can search for things with:
Thanks much just upgraded again now it installed complete with library, guess it was interrupted DL so it’s imperfect upgrade
sorry for a fuss
the env. variable /usr/share/kicad
