Make error when compiling bcwc_pcie

I have successfully extracted and installed the firmware thanks to UnaiM. Im following the instructions from the Get Started article, but when I runmake` I get errors:

That said, is it possible you're using linux kernel 3.10.0? That kernel is extremely old, and not supported.

[arun-gurung]

Youre right, its kernel 3.10.0-514.16.1.el7.x86_64 and Im running CentOS 7. Its the stock kernel that came with the operating system. I guess I have to upgrade.

[arun-gurung]

I upgraded to Linux 4.11.2 and now the camera works fine! Yay! Thanks so much to everyone who helped me.

No prob. Please close since the problem is solved.

Problem solved, case closed.
