I have no idea, how to compile this :(
I tried make, but with no luck.
I tried meson, just

meson builddir && cd builddir
meson compile

With no luck either:

../include/libucontext/bits.h:8:9: error: unknown type name 'greg_t'
typedef greg_t libucontext_greg_t;
        ^
../include/libucontext/bits.h:9:9: error: unknown type name 'ucontext_t'
typedef ucontext_t libucontext_ucontext_t;
        ^
../arch/aarch64/makecontext.c:24:16: error: offsetof requires struct, union, or class type, 'libucontext_ucontext_t' (aka 'int') invalid
_Static_assert(offsetof(libucontext_ucontext_t, uc_mcontext.regs[0]) == R0_OFFSET, "R0_OFFSET is invalid");
               ^        ~~~~~~~~~~~~~~~~~~~~~~
/Library/Developer/CommandLineTools/usr/lib/clang/13.0.0/include/stddef.h:104:24: note: expanded from macro 'offsetof'
#define offsetof(t, d) __builtin_offsetof(t, d)
                       ^                  ~
../arch/aarch64/makecontext.c:25:16: error: offsetof requires struct, union, or class type, 'libucontext_ucontext_t' (aka 'int') invalid
_Static_assert(offsetof(libucontext_ucontext_t, uc_mcontext.sp) == SP_OFFSET, "SP_OFFSET is invalid");
               ^        ~~~~~~~~~~~~~~~~~~~~~~
/Library/Developer/CommandLineTools/usr/lib/clang/13.0.0/include/stddef.h:104:24: note: expanded from macro 'offsetof'
#define offsetof(t, d) __builtin_offsetof(t, d)
                       ^                  ~

encoupled with an error "The deprecated ucontext routines require _XOPEN_SOURCE to be defined"

All in all, how can it be compiled and installed into the system?
I want to use it instead of makecontext and others while porting source code of my project to M1

try compile like that:
For object files:
cd arch/aarch64 && cc *.c *.S -I. -I../common -Iinclude -I../../include -fPIC -DPIC -O2 -ggdb3 -D_BSD_SOURCE -std=gnu99 -c
Archive objects to static library (libucontext.a):
ar rcs libucontext.a *.o
Compile objects to dynamic library (libucontext.dylib):
cc -dynamiclib -o libucontext.1.dylib -compatibility_version 1 -current_version 1 *.o

The non-Meson build system should now work. I'll cut a new release shortly.
