刚在经过翻新的机器(2GB内存,2GHz双核)上以Xubuntu 14.04入手,并且对c具有粗略的/读过的知识,但不是ac程序员。
我正在尝试编译在这里找到的代码,以便为在工作空间之间移动的行为创建可视通知。编码:
// wschanged.c
#include <libwnck/libwnck.h>
#include <stdlib.h>
static void
on_active_workspace_changed (WnckScreen *screen,
WnckWorkspace *space,
gpointer data)
{
// Executes a script on workspace change
system ("~/.workspace-changed");
}
int main(int argc, char ** argv)
{
GMainLoop *loop;
WnckScreen *screen;
glib:gdk_init (&argc, &argv);
loop = g_main_loop_new (NULL, FALSE);
screen = wnck_screen_get_default();
g_signal_connect (screen, "active-workspace-changed",
G_CALLBACK (on_active_workspace_changed), NULL);
g_main_loop_run (loop);
g_main_loop_unref (loop);
return 0;
}
编译命令:
gcc -O2 -DWNCK_I_KNOW_THIS_IS_UNSTABLE -o wschanged `pkg-config --cflags --libs libwnck-3.0` wschanged.c
我收到的错误:
wschanged.c: In function ‘on_active_workspace_changed’:
wschanged.c:12:12: warning: ignoring return value of ‘system’, declared with attribute warn_unused_result [-Wunused-result]
system ("~/.workspace-changed");
^

我拥有最新版本的libwnck,并且还添加了:
#include <glib.h>
看看这是否可以解决似乎源自对glib包中对象的未定义引用的错误,但这并没有更改任何错误输出。
任何建议将不胜感激!
