About

This is some test code and tooling to help developing Userland BSD on Linux project.

Content

• min.c: minimal x86-64 "Hello-world" program for both Linux and FreeBSD written in C intrinsics.
• mid.c: equivalent in pure C.
• Makefile: BSD make makefile to build min, mid (mid.c statically linked) and max (mid.c linked dinamically) and run sym_extract.py to generate target_os_defs.h.
• sym_extract.py: tool used to extract only relevant defines and structs from the FreeBSD kernel sources.
• *.econf: extraction rules
