Having issues building gnss test app

I am trying to build gnss test app I have got from the github repository, but it fails at compiling.
problem are missing functions:
le_gnss_StartMode
le_gnss_GetSupportedConstellations
and also come global variables:
LE_GNSS_HOT_START
LE_GNSS_WARM_START

functions I assume should be provided by the interface le_gnss.api:

but can`t find them.

Are these samples working ones?

problem is solved, I was compiling the wrong app.
