Tried my best to contribute to this project. I have a couple of tips for you.

• Consider using CMake to configure and build your project, which is more beginner friendly.
• Be careful of which system headers you're using, as not all functions defined by them can be run in kernel space. You may need to reimplement them.
• Try to move definitions into header files (.h) then include them in source files (.c) instead.
• You'll need to configure include paths accordingly.
• Check for syntax errors much more often, or use an integrated development environment to do it for you. The latter will give suggestions whilst you're writing code, increasing efficiency.

And lastly,

- #define <typename> <type>
+ typedef <typename> <type>;
