hilbert os is a 64-bit hobby operating system, which is not very mature yet. to
build and test it, you will need some software installed. on debian, i believe
the packages listed below are sufficient.
- bison
- flex
- g++
- gdb
- git
- libgmp-dev
- libmpfr-dev
- libmpc-dev
- make
- nasm
- qemu-system-x86
- texinfo
- xorriso
next, you will need to download and compile some dependencies. the script in
setup.sh will do this for you. if it sees an environment variables MAKEOPTS, it
will pass the contents of that as arguments to invocations of make. otherwise,
it defaults to "-j$(nproc)". if you nead to clean that setup for any reason,
you can use the script in clean-setup.sh.
now that we have all the dependencies, just run "make". the default target is
build/disk.iso, a bios-bootable disk image. you can run "make debug" to start
qemu with that disk, and attach gdb to it. you can also use "make clean" to
remove all of the files that "make" creates.

i patch the <stddef.h> header file with patches/minstuki-stddef.patch
to add a max_align_t type to make libstdc++ happy. i use the commit

about that file changing in a future commit.
