Error : undefined reference

Hi, there.
I’m trying to use the Navio+ on RaspberryPi first time.
When i compile the example file, I see the error message as follows.
Please help me, if you know to solve this problem.

Hello Jeremy

That’s because we use our own drivers, no need for WiringPi lib. In each Example directory there is a makefile. To compile just type make. Then run with sudo ./AccelGyroMag.

Please, refer to the docs

I got it. Thank you for helping me.
