Greetings all.
Beating my own expectations it seems i got past the compile step for
pylonGPS.
However, now i get an error that seems to indicate linking to reach for
host files instead of cross compiled. My understanding was that bitbake
handles that... what do i have to look for ?
Thanks for your support...
see -L/usr/lib/x86_64-linux-gnu in you commandline there, thats a
problem you need to look into. Its possible that pylongps's own build
system hardcodes it into linker flags, which is a problem for cross
compiling.
