Question

我想在msys2（Windows 7）上创建一个使用Gtk3的GtkPlug的简单程序。但是我收到了一个链接错误，如下所示。

$ gcc `pkg-config --cflags gtk+-win32-3.0` -o plug plug.c `pkg-config --libs gtk+-win32-3.0`
plug.c: In function 'main': plug.c:22:23: warning: initialization makes pointer from integer without a cast
[enabled by default]
     GtkWidget *plug = gtk_plug_new(0);
                       ^

C:\msys32\tmp\ccTQ2pkd.o:plug.c:(.text+0x15f): undefined reference to `gtk_plug_add'
collect2.exe: error: ld returned 1 exit status

plug.c

#include <gtk/gtk.h>

static void destroy(GtkWidget *widget, gpointer data)
{
    gtk_main_quit();
}

static void embed_event(GtkWidget *widget, gpointer data)
{
    g_print("Embed event occurred");
}

static void entry_activated(GtkWidget *widget, gpointer data)
{
    g_print("Entry activated");
}

int main(int argc, char *argv[])
{
    gtk_init(&argc, &argv);

    GtkWidget *plug = gtk_plug_new(0);
    g_print("%i", gtk_plug_get_id(GTK_PLUG(plug)));
    g_signal_connect(plug, "destroy", G_CALLBACK(destroy), NULL);
    g_signal_connect(plug, "embed-event", G_CALLBACK(embed_event), NULL);

    GtkWidget *entry = gtk_entry_new();
    gtk_entry_set_text(GTK_ENTRY(entry), "Plug and Socket");
    g_signal_connect(entry, "activate", G_CALLBACK(entry_activated), NULL);
    gtk_plug_add(GTK_PLUG(plug), entry);

    gtk_widget_show_all(plug);

    gtk_main();

    return 0;
}

gcc.exe（GCC）4.8.1 [32bit]
mingw32 / mingw-w64-i686-gtk3 3.18.0-1

一个简单的Gtk程序，它不使用我可以制作的GtkPlug。

请有人能给我适当的解决方案吗？
