操作系统真相还原之bochs环境配置

bochs 2.6.2 下载地址：https://sourceforge.net/projects/bochs/files/bochs/2.6.2/

configure

./configure \
--prefix=/home/lihaifei/bochs-2.6.2 \
--enable-debugger \
--enable-disasm \
--enable-iodebug \
--enable-x86-debugger \
--with-x \
--with-x11

报错1: configure: error: no acceptable C compiler found in $PATH

sudo yum install gcc

报错2:configure: error: C++ preprocessor "/lib/cpp" fails sanity check

yum install -y gcc-c++

make

报错1: gtk_enh_dbg_osdep.cc:20:21: fatal error: gtk/gtk.h: No such file or directory

sudo yum install gtk2 gtk2-devel gtk2-devel-docs

需要重新执行 configure

** 报错2:**

/usr/bin/ld: gui/libgui.a(gtk_enh_dbg_osdep.o): undefined reference to symbol 'pthread_create@@GLIBC_2.2.5'
//usr/lib64/libpthread.so.0: error adding symbols: DSO missing from command line

解决：vim Makefile 文件， 在 92 行增加 -lphread.然后重新 make

bochs初启动

# 设置虚拟机内存为32MB
megs: 32
# 设置BIOS镜像
romimage: file=$BXSHARE/BIOS-bochs-latest 
# 设置VGA BIOS镜像
vgaromimage: file=$BXSHARE/VGABIOS-lgpl-latest
# 设置从硬盘启动
boot: disk
# 设置日志文件
log: bochsout.txt
# 关闭鼠标
mouse: enabled=0
# 打开键盘
keyboard: type=mf, serial_delay=250
# 设置硬盘
ata0: enabled=1, ioaddr1=0x1f0, ioaddr2=0x3f0, irq=14
# 添加gdb远程调试支持
gdbstub: enabled=1, port=1234, text_base=0, data_base=0, bss_base=0

执行步骤：

1. bin/bochs -f ./bochsrc.disk
2. bin/bximage -hd -mode='flat' -size=60 -q hd60M.img
3. 在代码文件中ata0: enabled=1, ioaddr1=0x1f0, ioaddr2=0x3f0, irq=14增加：
   ata0-master: type=disk, path="hd60M.img", mode=flat, cylinders=121, heads=16, spt=63
4. bin/bochs -f ./bochsrc.disk,执行成功后按下 c ，继续下一步。

在bochs启动过程中出现错误“invalid choise core2_penryn_t9600”引起“cpu directive malformed”

解决：

1. bochs -help cpu
将显示出所有支持的CPU类型
2. 修改.bochsrc文件中cpu: model=core2+penryn_t9600为cpu: model=上一条查到的所支持的CPU类型之一

解决方法：
注释最后一行，禁用gdb调试。参考：https://zhuanlan.zhihu.com/p/390664291
