*** NOTE: the resolution is:

$ diff rtl_airband.cpp rtl_airband.cpp.bak.orig

< if(1) {

  if(__builtin_cpu_supports("sse")) {

This results in the build of rtl_airband in the directory.

And it does seem to run.... I will have to connect up some additional RTL's and get some antenna work done to test things more. My main RTL is in use on mission critical op right now....

So the instructions say to run ./rtl_airband_neon

BUT

this was not built... just rtl_airband

Is the neon version just for the SoC devices?

[szpajder]

Yes, _neon is for Raspberry Pi V2, while _vfp is for Pi V1. x86 binary has no suffix.

ok.. might want to update the x86 build info ;)

So I have it built, and dug out a 2nd device, and running... no antenna yet... as I have to get setup for multiple dongles...

Getting feeds to the server, and what I guess is the "scanning" screen... So looks GOOD! I will advise as soon as I can wire in my antenna(s) and compare with my regular receivers... but looks good!

THAAANKKKKKKKSSSSS!

I've got a couple other comments for issues/suggestions for the future....

but

THANKKKKKKKKKSSSSSSSSSSSSS AGAIN!!!!! DESKTOP BUILD WOOOT WOOOWOOT!!!
