note: I'm using USB-Serial converter. (I attached NRF24l01 via usb port):

root@Fi:~/ali/RF24# lsusb 
Bus 001 Device 004: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter

I tested on Kali Linux and Rasspbian debian-based linux distributions.

Add "-marm" extra flag at that CFLAGE line in Makefile.inc.

[ludiazv]

The configure script do not detect the rpi3 it fallback to RPi 1/Zero compilation ARMV6. You can force to compile with option --soc=BCM2836 (RPI2).

On the other hand, AFAIK this library do not support USB inteface. In order to work with the library you need to wire the radios to the SPI pins of the Pi.

I got the same issue as @alimp5,

I tried both of @tomcatGu and @ludiazv solutions, nevertheless changing the CFLAG in the Makefile.inc does not help, as well as the --soc=BCM2835 (RPi3) option (./configure --driver=SPIDEV --soc=BCM2835).

I edited the Makefile.inc with sudo nano Makefile.inc from: CFLAGS=-march=armv6zk -mtune=arm1176jzf-s [...] to: CFLAGS=-marm -march=armv6zk -mtune=arm1176jzf-s [...]

however everytime I execute sudo make install -B and inspect the Makefile.inc after the same error message, the -marm flag has been removed, net even properly added.

Seems like it does ignore the set driver via the config file. I tried it with the MRAA driver as well. Nevertheless the same result.

Additionally I should mention that I have connected the radio via SPI pins to my RPi3. Since both solutions didn`t work for me you guys got any other possible solutions?

Old issue, but for the record, after running configure, sudo make install should be run without the -B switch, else the configure script is re-run with default values.

Fixed in https://github.com/nRF24/RF24/commit/b323f535aa9644d988370fc6989a2ef9f85aa469
