barebones

This is not a joke: Read the Intel manual, maybe check out some of the learning repos on github that solves all the glue-stuff that isn't important. I have one such repo here: https://github.com/fwsGonzo/barebones

I have made a codebase where all the C and C++ glue is already taken care of, as well as the build system: https://github.com/fwsGonzo/barebones However, nothing else. So it's a starting point for a beginner. I don't know if its the perfect starting point or not, but at least you won't be stuck with all the setup. If you are writing an OS in another language you can probably get some inspiration as well, as for example I did implement basic ubsan support. Some fun facts: There is a C++ exceptions example that shows that with the compiler runtime as well as a libunwind you can catch C++ exceptions, but only if you create the exception fully yourself, as there is no standard library. It does add a bit of bloat, so it's not really intended for OS development. There is an example of how to runtime load a library, and call into it. No runtime
