microCORE builds using the x86_64-elf-gcc cross-compiler. You cannot install this cross compiler through prebuilt packages, as the compiler used specifically for microCORE is built with special options.
See this document for more info.
The maintainer of this project strictly requires all code follow a styleguide. Any contributions made that do not follow the styleguide, no matter how helpful they may be, will be rejected.
See the styleguide for more info.
microCORE uses very specific calling conventions. When writing C++ code, the following information is rather useless to you.
However, when writing assembly, it is critical that you follow this guide.
See the calling conventions for more info.
