Error : etup my raspberry pi to receive message from Arduino using C++ code

Question

Hi

I am trying to setup my raspberry pi to receive message from Arduino using C++ code. I am getting a below error message.

pi@raspberrypi:~ $ sudo g++ -Wall -Ofast -mfpu=vfp -mfloat-abi=hard -march=armv6zk -mtune=arm1176jzf-s -L../librf24/ -lrf24 *.cpp -o receive
Receive.cpp:8:39: error: invalid conversion from ‘const char*’ to ‘uint16_t {aka short unsigned int}’ [-fpermissive]
