我开始在我的 C++ 项目中使用 Tup。我目前的一个是游戏，分为 3 个部分：
- 第一个是主目录“osumax”；
- 第二个是我的游戏框架“osumax/Libraries/ns_framework”；
- 最后是游戏数据“osumax/Libraries/osumax_shared”的API；
目前，osumax_shared 中没有任何内容，因为我正在研究框架。
ns_framework 和 osumax_shared 是动态库（我在Linux下，所以有.so文件）。
libns_framework.so 构建时甚至没有警告，但是当主可执行文件的构建开始时，我有很多错误，只有未定义的引用。有些来自 ns_framework，我可以理解，但我也在使用 TinyXML2（随 apt-get 安装），并且该库中有许多未定义的引用。
这是完整的输出：

链接命令是这个：

我在这里给你两个 Tup 文件（对不起法语评论）：
- 对于主文件夹（osumax）：http ://pastebin.com/zKgzyYxt
- 对于第一个库（ns_framework）：http ://pastebin.com/mhTA4p73
那么，这些错误是来自 Tup 构建系统，还是来自我？
我真的不明白我的错误在哪里，或者如果我做错了什么是 tup 配置。
谢谢你的帮助 ！
