任何人都可以帮助我与此我有这个代码在制造商文件

COMPILER = gcc
LINKER = ld
ASSEMBLER = nasm
CFLAGS = -m32 -c -ffreestanding
ASFLAGS = -f elf32
LDFLAGS = -m elf_i386 -T src/link.ld

run: all
    $(EMULATOR) $(EMULATOR_FLAGS) $(OUTPUT)

all:$(OBJS)
    mkdir iknow/ -p
    mkdir iknow/boot/ -p
    $(LINKER) $(LDFLAGS) -o $(OUTPUT) $(OBJS)

obj/kasm.o:src/kernel.asm
    $(ASSEMBLER) $(ASFLAGS) -o obj/kasm.o src/kernel.asm
    
obj/kc.o:src/kernel.c
    $(COMPILER) $(CFLAGS) src/kernel.c -o obj/kc.o

    $(COMPILER) $(CFLAGS) src/idt.c -o obj/idt.o

    $(COMPILER) $(CFLAGS) src/kb.c -o obj/kb.o

obj/isr.o:src/isr.c
    $(COMPILER) $(CFLAGS) src/isr.c -o obj/isr.o

obj/screen.o:src/screen.c
    $(COMPILER) $(CFLAGS) src/screen.c -o obj/screen.o

obj/string.o:src/string.c
    $(COMPILER) $(CFLAGS) src/string.c -o obj/string.o

    $(COMPILER) $(CFLAGS) src/shell.c -o obj/shell.o

build:all
    #Activate the install xorr if you do not have it already installed
    #sudo apt-get install xorriso
    rm iknow/boot/grub/ -r -f
    mkdir iknow/boot/grub/
    echo set default=0 >> iknow/boot/grub/grub.cfg
    echo set timeout=0 >> iknow/boot/grub/grub.cfg

    echo         set root='(hd96)' >> iknow/boot/grub/grub.cfg
    echo         multiboot /boot/kernel.bin >> iknow/boot/grub/grub.cfg
    echo } >> iknow/boot/grub/grub.cfg

    grub-mkrescue -o iknow.iso iknow/
    
clear:
    rm -f obj/*.o
    rm -r -f iknow/

在使用所有权限和root权限运行它后，它会生成此错误
