configure: making C++-safe versions of Linux kernel headers (may take a while)
checking for C++-includable kernel header files... no
configure: WARNING:
=========================================

Your Linux kernel header files cause errors when included by a C++ program,
so I won't try to compile the linuxmodule driver.

Click modifies the Linux kernel's header files to make them work with
C++, using the program 'linuxmodule/click-linuxtool.pl'. It looks like
your kernel header files have features the tool doesn't know how to fix.
You can report this error to us via a Github issue, or, even better,
try to fix the error. See the config.log file for more information on the
error.
