Global variables use more memory than they should

Other Hardware 3rd Party Boards

I am trying to compile a simple sketch for Arduino Nano and Uno (Atmega328), but I'm getting the same error for both these boards. I included 3 libraries and the dynamic memory usage jumped up to 155%!.
Now I know that these libraries are not that large, so what may be wrong in my setup? I am not getting this error with my SAMD21 board.

I have tried updating my Arduino AVR Boards to version 1.6.23 but that didn't fix the problem.

#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
RF24 radio(7, 8); // CE, CSN
const byte address[6] = "00001";
void setup() {

}
void loop() {

}

The Compiler output:

Sketch uses 6266 bytes (19%) of program storage space. Maximum is 32256 bytes.
Global variables use 3183 bytes (155%) of dynamic memory, leaving -1135 bytes for local variables. Maximum is 2048 bytes.
Not enough memory; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing your footprint.
Error compiling for board Arduino/Genuino Uno.

If I compile the posted code for my Uno I get:

Sketch uses 532 bytes (1%) of program storage space. Maximum is 32256 bytes.
Global variables use 33 bytes (1%) of dynamic memory, leaving 2015 bytes for local variables. Maximum is 2048 bytes.

That is with Arduino AVR Boards version 1.6.23 and IDE version 1.8.5.

Are you sure that that is the exact code that you attempted to upload?
