c++ - Raspberry PI 2 未定义引用

Question

我有一个新的 RasPi 2，我已经安装了最新版本的 Raspbian 以及编译我正在处理的项目所需的所有库。这些库是在“sudo apt-get update”之后从存储库安装的，因此它们应该是最新版本。

项目的编译工作正常，但在链接时出现以下错误:

可能是什么问题，我该如何解决？

谢谢!

我也遇到了同样的错误，但是通过阅读 libglib-2.0.so 解决了问题。
因为您帖子中显示的 undefined reference 应包含在/lib/arm-linux-gnueabihf/libglib-2.0.so 中，所以项目必须读取该库。
检查库路径或库搜索路径可能是个好主意。
抱歉我的英语不好。
