如何修复 ld: 找不到 kernel.bin: 没有那个文件或目录
How to fix ld: cannot find kernel.bin: No such file or directory
我正在尝试 运行 操作系统的实现,当我在终端上 运行 时出现此错误,我使用 ubuntu 20.04.
这是生成文件:
C_SOURCES = $(wildcard kernel/*.c drivers/*.c cpu/*.c libc/*.c)
HEADERS = $(wildcard kernel/*.h drivers/*.h cpu/*.h libc/*.h)
# Nice syntax for file extension replacement
OBJ = ${C_SOURCES:.c=.o cpu/interrupt.o}
# Change this if your cross-compiler is somewhere else
CC = /usr/local/i386elfgcc/bin/i386-elf-gcc
GDB = /usr/local/i386elfgcc/bin/i386-elf-gdb
# -g: Use debugging symbols in gcc
CFLAGS = -g -ffreestanding -Wall -Wextra -fno-exceptions -m32
# First rule is run by default
os-image.bin: boot/bootsect.bin kernel.bin
cat $^ > os-image.bin
# '--oformat binary' deletes all symbols as a collateral, so we don't need
# to 'strip' them manually on this case
kernel.bin: boot/kernel_entry.o ${OBJ}
ld -melf_i386 -o -no-PIE $@ -Ttext 0x1000 $^ --oformat binary
# Used for debugging purposes
kernel.elf: boot/kernel_entry.o ${OBJ}
ld -melf_i386 -o -no-PIE $@ -Ttext 0x1000 $^
run: os-image.bin
qemu-system-i386 -fda os-image.bin
# Open the connection to qemu and load our kernel-object file with symbols
debug: os-image.bin kernel.elf
qemu-system-i386 -s -fda os-image.bin -d guest_errors,int &
${GDB} -ex "target remote localhost:1234" -ex "symbol-file kernel.elf"
# Generic rules for wildcards
# To make an object, always compile from its .c
%.o: %.c ${HEADERS}
${CC} ${CFLAGS} -c $< -o $@
%.o: %.asm
nasm $< -f elf -o $@
%.bin: %.asm
nasm $< -f bin -o $@
clean:
rm -rf *.bin *.dis *.o os-image.bin *.elf
rm -rf kernel/*.o boot/*.bin drivers/*.o boot/*.o cpu/*.o libc/*.o
这是代码的来源,我无法安装教程中的交叉编译器。所以我尝试更改 makefile 以使用默认的 gcc:
您的链接器命令有错误,因为您放错了 -no-PIE
选项。
而不是 ld -o -no-PIE $@
,写 ld -o $@ -no-PIE
:
kernel.bin: boot/kernel_entry.o ${OBJ}
ld -melf_i386 -o $@ -no-PIE -Ttext 0x1000 $^ --oformat binary
kernel.elf: boot/kernel_entry.o ${OBJ}
ld -melf_i386 -o $@ -no-PIE -Ttext 0x1000 $^
$@
是您的 make 命令的目标(这里是 kernel.bin
和 kernel.elf
)。像你一样错放它,你在指示 ld
将结果输出为名为 -no-PIE
的文件,并使用 kernel.bin
(resp. kernel.elf
)作为输入。由于输入尚不存在,因此出现错误消息。
