使用centos7 (遇到坑不少)

bochs-gdb安装(2.7)

由于bochs的GDB要么本地要么远程, 所以我们得整两个bochs, 这个就当bochs-gdb

参考地址 https://zhuanlan.zhihu.com/p/492780020

依赖库安装

sudo yum install gtk2 gtk2-devel libXt libXt-devel libXpm libXpm-devel SDL SDL-devel libXrandr-devel.x86_64 xorg-x11-server-devel glibc-headers gcc-c++ SDL SDL-devel

安装nasm

wget https://www.nasm.us/pub/nasm/releasebuilds/2.15.05/nasm-2.15.05.tar.gz
tar xvzf nasm-2.15.05.tar.gz
cd nasm-2.15.05
./configure
make
sudo make install

下载bochs

wget https://sourceforge.net/projects/bochs/files/bochs/2.7/bochs-2.7.tar.gz --no-check-certificate
tar xvfz bochs-2.7.tar.gz
mv bochs-2.7 bochs-gdb
cd bochs-gdb

配置文件

./configure --with-x11 --with-x --enable-all-optimizations --enable-readline --enable-a20-pin --enable-fast-function-calls --enable-gdb-stub

./configure --with-x11 --with-wx --enable-disasm --enable-all-optimizations --enable-readline --enable-long-phy-address --enable-ltdl-install --enable-idle-hack --enable-plugins --enable-a20-pin --enable-x86-64 --enable-cpu-level=6 --enable-large-ramfile --enable-repeat-speedups --enable-fast-function-calls --enable-handlers-chaining --enable-trace-linking --enable-configurable-msrs --enable-show-ips --enable-cpp --enable-debugger-gui --enable-iodebug --enable-logging --enable-assert-checks --enable-fpu --enable-vmx=2 --enable-svm --enable-3dnow --enable-alignment-check --enable-monitor-mwait --enable-avx --enable-evex --enable-x86-debugger --enable-pci --enable-usb --enable-voodoo --enable-gdb-stub

复制文件(保留,不需要执行, 这个是2.6.8遗留)

cp misc/bximage.cpp  misc/bximage.cc
cp iodev/hdimage/hdimage.cpp iodev/hdimage/hdimage.cc
cp iodev/hdimage/vmware3.cpp  iodev/hdimage/vmware3.cc
cp iodev/hdimage/vmware4.cpp iodev/hdimage/vmware4.cc
cp iodev/hdimage/vpc-img.cpp iodev/hdimage/vpc-img.cc
cp iodev/hdimage/vbox.cpp iodev/hdimage/vbox.cc

修改makefile

vim Makefile

# prefix          = /usr/local
prefix          = /usr/local/bochs-gdb # 修改为你要存放的目录位置
exec_prefix     = ${prefix}
srcdir          = .

bindir          = ${exec_prefix}/bin
libdir          = ${exec_prefix}/lib
plugdir         = ${exec_prefix}/lib/bochs/plugins
datarootdir     = ${prefix}/share
mandir          = ${datarootdir}/man
man1dir         = $(mandir)/man1
man5dir         = $(mandir)/man5
docdir          = $(datarootdir)/doc/bochs
sharedir        = $(datarootdir)/bochs
top_builddir    = .
top_srcdir      = $(srcdir)

构建

sudo make && sudo make install

显示是这样就代表安装成功了

然后可以查看/usr/local/share /usr/local/bin 下面就有了 对应的东西

复制到bin目录下

cp /usr/local/bochs-gdb/bin/bochs /usr/local/bin/bochs-gdb  
cp /usr/local/bochs-gdb/bin/bximage /usr/local/bin/

创建硬盘

不同的bochs对应的bximage参数可能不同

yes | bximage -q -hd=16 -func=create -sectsize=512 -imgmode=flat maste

记录下来配置项 ata0-master: type=disk, path=“master.img”, mode=flat

创建启动脚本

export LTDL_LIBRARY_PATH=/usr/local/bochs-gdb/lib/bochs/plugins 
export BXSHARE=/usr/local/bochs-gdb/share/bochs 
bochs-gdb -q -f bochsrc-gdb

创建启动makefile

和上面二选一即可

debug: $(BUILD)/master.img

	LTDL_LIBRARY_PATH=/usr/local/bochs-gdb/lib/bochs/plugins \
	BXSHARE=/usr/local/bochs-gdb/share/bochs \
	bochs-gdb -q -f $(WORKDIR)/bochs/bochsrc-gdb

bochs安装

再解压一份bochs

tar xvfz bochs-2.7.tar.gz
mv bochs-2.7 bochs
cd bochs

配置文件

./configure --with-x11 --with-x --enable-all-optimizations --enable-readline --enable-a20-pin --enable-fast-function-calls  --enable-x86-debugger   --enable-debugger

./configure --with-x11 --with-wx --enable-debugger --enable-all-optimizations --enable-readline --enable-long-phy-address --enable-ltdl-install --enable-idle-hack --enable-plugins --enable-a20-pin --enable-x86-64 --enable-smp --enable-cpu-level=6 --enable-large-ramfile --enable-repeat-speedups --enable-fast-function-calls --enable-handlers-chaining --enable-trace-linking --enable-configurable-msrs --enable-show-ips --enable-cpp --enable-debugger-gui --enable-iodebug --enable-logging --enable-assert-checks --enable-fpu --enable-vmx=2 --enable-svm --enable-3dnow --enable-alignment-check --enable-monitor-mwait --enable-avx --enable-evex --enable-x86-debugger --enable-pci --enable-usb --enable-voodoo

–enable-gdb-stub 和 --enable-debugger 是互斥的, --enable-debugger 是本地调试 --enable-gdb-stub 是远程调试

构建

sudo make && sudo make install

复制到bin目录下

cp /usr/local/bochs/bin/bochs /usr/local/bin/bochs 
cp /usr/local/bochs/bin/bximage /usr/local/bin/bximage

编写boot.asm

[org 0x7c00]

; 设置屏幕模式为文本模式，清除屏幕
mov ax, 3
int 0x10

; 初始化段寄存器
mov ax, 0
mov ds, ax
mov es, ax
mov ss, ax
mov sp, 0x7c00

mov si, 0

; 屏幕显示区域
mov ax,0xb800
mov ds,ax
; 显示字符H
mov byte [0],'H'   

; 阻塞
jmp $


; 填充 0
times 510 - ($ - $$) db 0

; 主引导扇区的最后两个字节必须是 0x55 0xaa
; dw 0xaa55
db 0x55, 0xaa

编译boot.asm

nasm -f bin boot.asm -o boot.bin

将boot.bin写入主引导扇区

dd if=boot.bin of=master.img bs=512 count=1 conv=notrunc

升级gcc

centos7 默认自带的gcc版本为4.8.5, 需要升级为11版本

sudo yum install centos-release-scl
sudo yum install devtoolset-11-gcc*
source /opt/rh/devtoolset-11/enable


mv /usr/bin/gcc /usr/bin/gcc-4.8.5

ln -s /opt/rh/devtoolset-11/root/bin/gcc /usr/bin/gcc

mv /usr/bin/g++ /usr/bin/g++-4.8.5

ln -s /opt/rh/devtoolset-11/root/bin/g++ /usr/bin/g++

gcc --version

g++ --version

升级gdb

mv /usr/bin/gdb  /usr/bin/gdb-7
sudo yum install texinfo  # 新版本的gdb需要这个东西
wget http://ftp.gnu.org/gnu/gdb/gdb-10.2.tar.gz
tar -xzvf gdb-10.2.tar.gz
cd gdb-10.2
./configure --prefix=/usr/     ## --prefix=/usr/参数实现自动配置环境变量
make
make install

qemu安装

进入到root用户

yum install qemu-kvm

转换磁盘镜像文件

qemu-img convert -f raw -O vmdk boot.img boot.vmdk
