How to build a kernel module on Raspbian?

[zfyseu]

Hello, everyone!
I want to build a kernel module on Rpi 2 based on raspbian.

And I follow the link "https://github.com/notro/rpi-source/wiki" to build the module.

However when I run the command "rpi-source" it returns the error：
ERROR:
gcc version check: mismatch between gcc (4.8.2) and /proc/version (4.9.3)

Is there anyone know how to solve it?
Thank you!

Use the rpi-source switch (--skip-gcc) to ignore that.
