安装bochs debugger GUI

1.概述

使用apt-get命令安装的bochs只能运行程序，不能debug程序。需要debug程序就必须用源码安装，能debug程序的bochs也分两种，一种是实用命令行debug，一种是可以使用GUI界面调试，相对来说使用GUI来调试更加方便快捷。

安装之前从https://sourceforge.net/projects/bochs/files/bochs/2.4.5/下载bochs-2.4.5，并且使用命令安装gcc和gtk：

sudo apt-get install build-essentialsudo apt-get install libgtk2.0-dev 

2.安装boots debugger命令行

<1>先将bochs解压到bochs-2.4.5文件夹下面，让然后进入文件夹bochs-2.4.5使用configure命令配置编译选项：

bochs-2.4.5$./configure   --enable-debugger --enable-disasm

<2>然后make编译

bochs-2.4.5$make

编译的时候会出错：

usr/bin/ld: gui/libgui.a(gtk_enh_dbg_osdep.o): undefined reference to symbol 'pthread_create@@GLIBC_2.1'//lib/i386-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line

修改该错误只需要在Makefile中的LIBS后面添加-lpthread，然后重新make即可。

<3>安装：

sudo  make install

<4>检查安装是否成功，运行bochs出现如下信息表示安装成功:

<5>如果运行bochs出现错误:

bochsrc:20: display library 'sdl' not available

  只需要将bochs配置文件bochrc中display_library:sdl删除即可。

3.安装 boots debugger GUI

<1>要安装带GUI的bochs, 首先进入文件夹bochs-2.4.5，然后使用configure命令配置bochs编译选项：

$./configure --with-x11 --with-wx --enable-disasm --enable-all-optimizations --enable-readline  --enable-debugger-gui --enable-x86-debugger --enable-a20-pin --enable-fast-function-calls --enable-debugger

<2>在Makefile中的LIBS后面添加-lpthread，然后make：

bochs-2.4.5$make

<3>安装bochs

sudo  make install

<4>修改bochs配置文件bochrc，在文件最后添加：

display_library: x, options="gui_debug"

<5>运行bochs：

选择6之后出现一个debug窗口，在debug窗口中可以用按钮调试程序，也可以通过输入命令debug：
