Question

我正在努力建立＆＃34; Wt＆＃34;我自己的库（在版本3.3.5中），但是当我尝试运行Example时失败了。

我的环境是一个带有Boost 1.53.0的Debian，我想为它构建库。

编译和链接（gcc 4.7.2）效果很好，但是当我尝试运行Wt-Example（http://www.webtoolkit.eu/wt/doc/tutorial/wt.html）时，服务器失败了：

Wt：致命错误：调用空的boost :: function

完整日志是：

有没有人知道如何找出这里出了什么问题？

我知道Boost版本不是最新的，但我想这不应该是一个问题吗？

我收到了这个警告：

<compilation debug="true" targetFramework="4.5.2"> <assemblies> <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" /> </assemblies> </compilation>

这看起来可能与事情有很大关系。

那就是说，它只是在我的Ubuntu盒子上使用g ++ - 5在valgrind下干净运行。（使用libc ++时无法链接）
