最近开始学习Linux编程，在Mate终端里试用了GDB的调试方式，对于习惯了用F5、F10和F11来调试的我来说，还真有点不习惯。于是我就把给Mate终端与GDB增加快捷键当作学习Linux编程的第一个实验目标来完成。现在我就把总结出来的方法分享给大家。
下载Mate终端源程序并解压缩：
链接: https://pan.baidu.com/s/1b8DCfkoHuKk0WSlKFXwVxQ密码: u5uu
里面有两个文件：
mate-terminal-1.21.0.tar.gz是原始源码包
mate-terminal-1.21.1.tar.xz是我改完的源码包
不想自己动手的的朋友可以下载我改过的包。编译安装方法在后面。
-
添加菜单
-
先将下面的菜单代码添加到src/terminal-window.c文件中的terminal_window_init函数，menu_entries数组，/* Terminal menu */段的前面。
/* Debugmenu */
{
"DebugProgram", NULL, N_("DebugProgram"), "F2",
NULL,
G_CALLBACK (debug_program_callback)
},
{
"DebugProcess", NULL,N_("Debug Process"), "F3",
NULL,
G_CALLBACK (debug_process_callback)
},
{
"DebugStart", NULL, N_("Debug Start"),"F4",
NULL,
G_CALLBACK (debug_start_callback)
},
{
"DebugContinue", NULL,N_("Debug Continue"), "F5",
NULL,
G_CALLBACK (debug_continue_callback)
},
{
"DebugNext", NULL, N_("Debug Next"),"F10",
NULL,
G_CALLBACK (debug_next_callback)
},
{
"DebugStep", NULL, N_("Debug Step"),"F11",
NULL,
G_CALLBACK (debug_step_callback)
},
再在/* Toplevel */段中的{ “Search”, NULL, N_(“_Search”) },下面加入
{ “Debug”, NULL, N_(“Debug”) },
-
将下面的菜单项添加到src/terminal.xml文件中的<menuaction="Terminal">段的前面。
-
打开po/ zh_CN.po文件，查找src/terminal-window.c段，将下面的字段添加到里面。
msgid"Debug"
msgstr"调试"
msgid"Debug Program"
msgstr"调试程序"
msgid"Debug Process"
msgstr"调试进程"
msgid"Debug Start"
msgstr"开始调试"
msgid"Debug Continue"
msgstr"继续执行"
msgid"Debug Next"
msgstr"单步执行"
msgid"Debug Step"
msgstr"进入函数"
msgid"Program Name"
msgstr"程序名称"
msgid"Name:"
msgstr"名称："
msgid"Process Id"
msgstr"进程ID"
-
添加调用代码
-
将下面代码添加到/src/terminal-window.c文件中的terminal_window_init (TerminalWindow *window)函数前面。

本来这样就应该可以了，但试用发现F5、F10和F11这三个键与Mate终端的按键有冲突，不得不加入代码屏蔽掉原有的快捷键。代码如下，将它们添加到window_key_press_cb函数returnFALSE;语句之前。
elseif(event->keyval == GDK_KEY_F5)
{
TerminalWindow *window =TERMINAL_WINDOW (widget);
GString *gstr;
gstr = g_string_new(NULL);
gstr = g_string_assign(gstr,"c\n");
vte_terminal_feed_child(VTE_TERMINAL(window->priv->active_screen), gstr->str, gstr->len);
g_string_free(gstr, TRUE);
return TRUE;
}
else if(event->keyval == GDK_KEY_F10)
{
TerminalWindow *window =TERMINAL_WINDOW (widget);
GString *gstr;
gstr = g_string_new(NULL);
gstr = g_string_assign(gstr,"n\n");
vte_terminal_feed_child(VTE_TERMINAL(window->priv->active_screen), gstr->str, gstr->len);
g_string_free(gstr, TRUE);
return TRUE;
}
else if(event->keyval == GDK_KEY_F11)
{
TerminalWindow *window =TERMINAL_WINDOW (widget);
GString *gstr;
gstr = g_string_new(NULL);
gstr = g_string_assign(gstr,"s\n");
vte_terminal_feed_child(VTE_TERMINAL(window->priv->active_screen), gstr->str, gstr->len);
g_string_free(gstr, TRUE);
return TRUE;
}
编译安装
本例是在ubuntukylin-18.04-enhanced-amd64系统下进行的，如果你没有安装过mate-common和yelp-tools执行下面命令安装它们。
sudoapt-get install mate-common
sudoapt-get install yelp-tools
注意命令执行完后是否有错误提示，如果有重新执行它们即可解决。
安装依赖库，执行：
sudo apt-get install libglib2.0-dev
sudo apt-get installlibvte-2.91-dev
sudo apt-get installlibdconf-dev
安装Mate终端，执行：
./autogen.sh
make
sudomake install
安装完成。
添加好的菜单界面如下图：
