bochs(2.6.11)配置安装
下载:https://bochs.sourceforge.io/
建议下载2.6.11,下文一开始安装的2.7,但运行时有无法解决的错误。但是大致安装过程一致。
linux
提前安装依赖
sudo apt-get install build-essentialsudo apt-get install xorg-dev
sudo apt-get install libgtk2.0-dev
接下来进行配置,以防万一全部配置上
./configure --with-x11 --with-wx --enable-debugger --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-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
进入root用户,之后的操作都在root下进行。
su root
开始编译
make
开始处理错误
- 错误1
No rule to make target "parser.cc" , needed by "parser.o" Stop.
进入bx_debug
文件夹下:
可以看到是后缀名的缘故,因此
cp parser.cpp parser.cc
- 错误2
config.h osdep.h cpu/decoder/decoder.h
然而这个文件确实存在于主目录下,因此
"config.h"--->"../config.h"
类似的
都需要更改一下头文件目录即可。
错误3
error: "XRRQueryExtension" was not declared in this scope; did you mean "XQueryExtension"?
更改
gui/x.cpp
,在首行添加#include <X11/extensions/Xrandr.h>
错误4
No rule to make target "misc/bximage.cc", needed by "misc/bximage.o"
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
错误5
error: invalid use of ‘this’ in non-member function 383 | # define BX_CPU_THIS_PTR this->
修改
bx_debug/dbg_main.cc
-Bit32u index = BX_ITLB_INDEX_OF(laddr);//改成下面一行
+ Bit32u index = BX_CPU(dbg_cpu)->ITLB.get_index_of(laddr);
......
- index = BX_DTLB_INDEX_OF(laddr, 0);
+ index = BX_CPU(dbg_cpu)->DTLB.get_index_of(laddr);
之后继续make
进行安装make install
运行bochs
因此删去默认的.bochsrc
中的955
行。
再次运行
安装成功!
测试
首先创建一个软盘
$ bximage
然后选择创建软盘,其余的默认即可
编写一段boot代码
org 07C00h ; 告诉编译器程序加载到07C00处 mov ax, cs
mov ds, ax
mov es, ax
call DispStr ; 调用显示字符串例程
jmp $ ; 无限循环
DispStr:
mov ax, BootMessage
mov bp, ax ; es:bp = 串地址
mov cx, 16 ; cx = 串长度
mov ax, 01301h ; ah = 13, al = 01h
mov bx, 000Ch ; 页号为0(bh = 0) 黑底红字 (bl = 0Ch,高亮)
mov dl, 0
int 10h ; 10h号中断
ret
BootMessage: db "Hello,OS world!"
times 510-($-$$) db 0 ; 填充剩下的空间,使生成的二进制代码恰好为512字节
dw 0xaa55
下载nasm
$ sudo apt-get install nasm
编译写入
nasm boot.asm -o boot.bin && dd if=boot.bin of=a.img bs=512 count=1 conv=notrunc
写一个bochs
配置文件,命名为sample_bochsrc
# how much memorythe emulated machine will have megs: 32
# filename of ROMimages
romimage:file=/usr/local/share/bochs/BIOS-bochs-latest
vgaromimage:file=/usr/local/share/bochs/VGABIOS-lgpl-latest
# what disk imageswill be used
floppya:1_44=a.img, status=inserted
# choose the bootdisk.
boot: floppy
# where do we sendlog messages?
log: bochsout.txt
# disable themouse
mouse: enabled=0
# enable keymapping, using Us layout as default
keyboard:keymap=/usr/local/share/bochs/keymaps/x11-pc-us.map
启动bochs
$ bochs -f sample_bochsrc
选择6. Begin simulation
接着按c
运行
此时bochs
界面便会出现我们想要的
