This usually means using `make` on most GNU/Linux distros, or `gmake` on other non-GNU systems.\n\nIt is recommended to build this project using a standard UNIX-like system, using a Clang/LLVM toolchain capable of cross compilation (the default, unless `KCC` and/or `KLD` are explicitly set).\n\nAdditionally, building an ISO with `make all` requires `xorriso`, and building a HDD/USB image with `make all-hdd` requires `sgdisk` (usually from `gdisk` or `gptfdisk` packages) and `mtools`.\n\n### Makefile targets\n\nRunning `make all` will compile the kernel (from the `kernel/` directory) and then generate a bootable ISO image.\n\nRunning `make all-hdd` will compile the kernel and then generate a raw image suitable to be flashed onto a USB stick or hard drive/SSD.\n\nRunning `make run` will build the kernel and a bootable ISO (equivalent to make all) and then run it using `qemu` (if installed).\n\nRunning `make run-hdd` will build the kernel and a raw HDD image (equivalent to make all-hdd) and then run it using `qemu` (if installed).\n\nFor x86_64, the `run-bios` and `run-hdd-bios` targets are equivalent to their non `-bios` counterparts except that they boot `qemu` using the default SeaBIOS firmware instead of OVMF.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmaxdevos49%2Fosdev","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmaxdevos49%2Fosdev","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmaxdevos49%2Fosdev/lists"}
