我已經寫了一個非常簡單的XFCE面板插件片段時足夠的參數傳遞到包裝，：嚴重錯誤：不加載我的XFCE插件
gcc -Wall -shared -o libtest.so -fPIC main.c `pkg-config --cflags --libs libxfce4panel-1.0` `pkg-config --cflags --libs gtk+-2.0`
：
#include <gtk/gtk.h>
#include <libxfce4panel/xfce-panel-plugin.h>
static void system_monitor_construct(XfcePanelPlugin *plugin);
XFCE_PANEL_PLUGIN_REGISTER(system_monitor_construct);
static void system_monitor_construct(XfcePanelPlugin *plugin)
{
GtkWidget *hvbox;
GtkWidget *label;
GtkOrientation orientation;
orientation = xfce_panel_plugin_get_orientation (plugin);
hvbox = xfce_hvbox_new (orientation, FALSE, 2);
gtk_widget_show(hvbox);
gtk_container_add (GTK_CONTAINER (plugin), hvbox);
label = gtk_label_new ("Hello GNOME!");
gtk_container_add (GTK_CONTAINER (hvbox), GTK_WIDGET (label));
gtk_widget_show(label);
}
編譯它libtest.so複製到/usr/lib/xfce4/panel-plugins，並在桌面上創建文件test.desktop在/usr/share/xfce4/panel-plugins與內容：
[Xfce Panel]
Type=X-XFCE-PanelPlugin
Encoding=UTF-8
Name=test
X-XFCE-Module=test
X-XFCE-Module-Path=/usr/lib/xfce4/panel-plugins
當我加載這個插件，我得到：
(process:5700): xfce4-panel-wrapper-CRITICAL **: Not enough arguments are passed to the wrapper
xfce4-panel(external): test-8: child exited with status 512
(xfce4-panel:5695): xfce4-panel-WARNING **: Plugin test-8 exited with status 2, removing from panel configuration

我在哪裏錯了？或者我錯過了什麼？
