Can't build on fresh RPi 3

[DanV410]

I have a Rasberry Pi 3B + that I just created an SD card for tonight using the Raspberry Pi imaging tool. I am able to install rtl-fm, rtl-test, etc. and get it running, but both times I've tried to build RTLSDR-Airband on a clean install I get the following errors:

I've installed all of the dependancies as described on the wiki, with no errors. Any ideas?

I haven't updated to bullseye yet, but here are the cmake flags that work for me on a rpi4:

-DPLATFORM=native -DNFM=TRUE -DRTLSDR=TRUE -DMIRISDR=FALSE -DSOAPYSDR=FALSE -DPULSEAUDIO=FALSE

[DanV410]

Definitely a bullseye thing. Same hardware, same commands work just fine on the older Raspbian I downloaded just now. Dan

Looks like the GPU_FFT code needs an update. I'll look into this when I'll have a spare moment. Meanwhile just build with PLATFORM=armv7-generic.

Fix pushed to unstable branch

That was fast, thank you!
