编译生成 iso

$ make
mkdir -p build/arch/x86_64
nasm -felf64 src/arch/x86_64/boot.asm -o build/arch/x86_64/boot.o
mkdir -p build/arch/x86_64

$ make iso
mkdir -p build/isofiles/boot/grub
cp build/kernel-x86_64.bin build/isofiles/boot/kernel.bin
cp src/arch/x86_64/grub.cfg build/isofiles/boot/grub
grub-mkrescue -o build/os-x86_64.iso build/isofiles 2> /dev/null
rm -r build/isofiles

关于 intel x86架构 物理机， ubuntu 22.04 操作系统执行 make iso 的时候出现错误的问题：
问题流程以及解决步骤，

1. 手动执行 grub-mkrescue -o build/os-x86_64.iso build/isofiles 2> /dev/null 没有报错但是也没有生成os-x86_64.iso镜像文件；
2. 手动执行 grub-mkrescue -o build/os-x86_64.iso build/isofiles 报错： grub-mkrescue: 错误: mformat invocation failed
3. 安装 mtools ；apt-get install mtools
4. 执行 make iso 可以正常执行了
