With the latest LUbuntu (instead of the latest raspian like in my
last mails) version of Banana Pi the following error results when
compiling gnuradio with the gnuradio build-script:

Yes. As has already been mentioned on this thread, on these devices,
you need to set some extra cmake flags. See our Embedded page and the
section on Native Compiling.

Yes, i know this. But this doesnt work on the raspian OS on Banana. On
Lubuntu for Banana this works now with this extra cmake flags.
Even with this information out there, I still don't understand why
people try and natively compile GNU Radio on these devices...
Because to make the experience that native compiling on these devices is
terrible :-)
In the future i will use cross compiling.
