On my system, I get a compilation error if I include
linux/capability.h as it does not have capget().

NAME
       capget, capset - set/get capabilities of thread(s)

SYNOPSIS
       #include <sys/capability.h>

       int capget(cap_user_header_t hdrp, cap_user_data_t datap);

Have you installed libcap? It contains the sys/capability.h header
file that you need.
