how to get kernel header file? - Stack Overflow
stackoverflow.com › questions › 6001659Feb 06, 2021 · Did installing the headers complete? If so then they should be installed in /usr/include and the include directives you gave should just work. Edit: First run: sudo apt-get update. To make sure you have the latest packages, then: sudo apt-get install linux-headers-$(uname -r) This is the one package that should contain all the kernel header files in Ubuntu.
