我从GIT接受了navit项目。
当我尝试启动navit时，得到以下输出：
duser@10.132.197.141：〜/ NAVIT / navit-0.5.0 + dfsg.1 / build / navit $ ./navit 从源目录运行
error:navit:graphics_new:Failed to load graphics plugin gtk_drawing_area.
error:navit:event_add_watch:Can't find event system method add_watch. Event system is not set.
error:navit:event_remove_timeout:Can't find event system method remove_timeout. Event system is not set.
error:navit:xinclude:Unable to include /home/duser/NAVIT/navit-0.5.0+dfsg.1/build/navit/maps/*.xml
error:navit:navit_init:Warning: No graphics subsystem available.
error:navit:event_main_loop_run:Can't find event system method main_loop_run. Event system is not set.
出了什么问题？有什么建议吗？
谢谢。
