我目前正在操作系统上,我的问题是关于从MakeFile创建的mykernel.iso。我的发行版是Kali Linux,我遇到的问题与引导有关。
在我的目录中,我有Makefilekernel.cppkernel.olinker.dloader.oloader.stypes.hmykernel.omykernel.iso。当我使用VirtualBox引导mykernel.iso时,出现错误



(也mykernel.iso应该是4 mb,我的是340 kb)

以下是代码:


GCCPARAMS = -m32 -fno-use-cxa-atexit -nostdlib -fno-builtin -fno-rtti -fno-exceptions -fno-leading-underscore
ASPARAMS = --32
LDPARAMS = -melf_i386

objects = loader.o kernel.o



%.o: %.cpp
    gcc $(GCCPARAMS) -c -o $@ $<

%.o: %.s
    as $(ASPARAMS) -o $@ $<

mykernel.bin: linker.ld $(objects)
    ld $(LDPARAMS) -T $< -o $@ $(objects)

mykernel.iso: mykernel.bin
    mkdir iso
    mkdir iso/boot
    mkdir iso/boot/grub
    cp mykernel.bin iso/boot/mykernel.bin
    echo 'set timeout=0'                      > iso/boot/grub/grub.cfg
    echo 'set default=0'                     >> iso/boot/grub/grub.cfg
    echo ''                                  >> iso/boot/grub/grub.cfg
    echo 'menuentry "My Operating System" {' >> iso/boot/grub/grub.cfg
    echo '  multiboot /boot/mykernel.bin'    >> iso/boot/grub/grub.cfg
    echo '  boot'                            >> iso/boot/grub/grub.cfg
    echo '}'                                 >> iso/boot/grub/grub.cfg
    grub-mkrescue --output=mykernel.iso iso
    rm -rf iso

run: mykernel.iso
    (killall VirtualBox && sleep 1) || true
    VirtualBox --startvm 'My Operating System' &

install: mykernel.bin
    sudo cp $< /boot/mykernel.bin

kernel.cpp:
#include "types.h"

void printf(char* str)
{
    static uint16_t* VideoMemory = (uint16_t*)0xb8000;

    for(int i = 0; str[i] != '\0'; ++i)
        VideoMemory[i] = (VideoMemory[i] & 0xFF00) | str[i];
}



typedef void (*constructor)();
extern "C" constructor start_ctors;
extern "C" constructor end_ctors;
extern "C" void callConstructors()
{
    for(constructor* i = &start_ctors; i != &end_ctors; i++)
        (*i)();
}



extern "C" void kernelMain(const void* multiboot_structure, uint32_t /*multiboot_magic*/)
{
    printf("Welcome To My Operating System");

    while(1);
}

有什么建议吗?

最佳答案

看起来您在Kali Distro上。切换到Ubuntu并应用

sudo apt-get install xorriso

应该像一个有魅力的儿子一样工作。
