Re: [Discuss-gnuradio] Compiling GNURadio on BananaPI

[Andreas Ladanyi]

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.
