There are a couple of ways to resolve this and its dependent on the OS you are using.
Here is what I did using the Ubuntu 22.04 image from AWS is to install the linux header files and creating the appropriate links s.t. the C preprocessor can locate them, here're the details:

• Install the headers sudo apt install -y linux-headers-$(uname -r); header files will be at /usr/include/linux.
• The default includes is /usr/local/include and you can create the symbolic links for the various <sys/xxx.h> files by linking the headers from the first step over into this folder.

Please how to create symbolic links various <sys/xxx.h>, this is my command

ln -s /usr/local/include  /usr/include/linux

but I have same error

@gaffeyQiu First create the folder sys if it doesn't exist then individually link the sysctl.h file:

sudo mkdir /usr/local/include/sys
sudo ln -s /usr/include/linux/sysctl.h /usr/local/include/sys/sysctl.h

Worked for me.
Thanks for the tip @raymondtay!

#77 should fix the problem on the linux.
