[i=s] 本帖最后由 樱花流逝 于 2016-1-26 22:41 编辑 代码是这样的 [mw_shl_code=c,true]#include<stdio.h> #include<glib.h> #include<dbus/dbus-glib-lowlevel.h> static gboolean send_ding(DBusConnection *bus); int main(){ GMainLoop* loop; DBusConnection *bus; DBusError error; loop=g_main_loop_new(NULL,FALSE); dbus_error_init(&error); bus=dbus_bus_get(DBUS_BUS_SESSION,&error); if(!bus){ g_warning("connecting failure to D-bus: %s",error.message); dbus_error_free(&error); return 1; } dbus_connection_setup_with_g_main(bus,NULL); g_timeout_add(1000,(GSourceFunc)send_ding,bus); g_main_loop_run(loop); return 0; } static gboolean send_ding(DBusConnection *bus){ DBusMessage *message; message=dbus_message_new_signal("/com/burtonini/dbus/ding", "com.burtonini.dbus.Signal", "ding"); dbus_message_append_args(message, DBUS_TYPE_STRING,"ding!", DBUS_TYPE_INVALID); dbus_connection_send(bus,message,NULL); dbus_message_unref(message); g_print("ding!\n"); return 0; }[/mw_shl_code] 编译命令是这样的 gcc `pkg-config --cflags --libs dbus-glib-1` -g -o send dbus-ding-send.c 但是运行时终端显示“段错误”并直接退出了 用gdb调试时结果是这样的 [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". Program received signal SIGSEGV, Segmentation fault. strlen () at ../sysdeps/x86_64/strlen.S:106 106 ../sysdeps/x86_64/strlen.S:没有那个文件或目录 然而还是不知道错在哪orz 求解答
