GtkStatusIcon和GtkMenu的问题

[牙签儿]

想实现这样的一个测试程序：
使用GtkStatusIcon常驻通知区域，然后点击右键弹出GtkMenu，按照教程和Gtk＋2.0文档编写了如下代码，一直有个问题编译通不过，编译时的信息如下：

neo@neo:~/project$ gcc `pkg-config --libs --cflags gtk+-2.0` -o tray tray_test.c
tray_test.c:26: error: conflicting types for ‘status_icon’
tray_test.c:25: error: previous definition of ‘status_icon’ was here
tray_test.c:92: error: conflicting types for ‘status_icon’
tray_test.c:91: error: previous definition of ‘status_icon’ was here
tray_test.c:167: error: conflicting types for ‘exit_app’
tray_test.c:22: error: previous declaration of ‘exit_app’ was here

有会的朋友旁观者清帮我看一下，谢谢了
代码如下：

你在22行定义的函数只有一个实参（GtkWidget） 而166行的却是两个（GtkMenuItem, gpointer ）类型也不匹配。
25和26行 有两个变量同名 ，你改一下。91.92的错误相同。
我随便改了一下，能通过编译 。
