我是Qt的新手，我已经接受了这项任务......
使用GPS检测国家/地区 - 并在文本框中显示。
好吧，因为我是新手，我不知道怎么做这样的事情。我开始通过互联网搜索
我最终来到这里：http://www.developer.nokia.com/Community/Wiki/File:Qt_for_Maemo_Location_Example.zip
所以我下载了代码并运行它，出现了大量的错误

所以我做错了吗？有没有更简单的方法来做这些事情？请具体，我将不胜感激
答案 0 :(得分：0)
嗯，第一个错误确实说明了一切：“hildon/hildon-banner.h：没有这样的文件或目录”。
你至少缺少那个文件。可能该文件声明为LocationGPSDeviceFix，这解释了第二个错误“'LocationGPSDeviceFix'尚未声明”。从那里开始走下坡路。在C ++中，您应该从上到下开始修复错误。
