在Windows上与Witty（Wt）和Mingw64链接

Question

在Windows cmd和/或msys上的MingW64上使用Wt库进行编译时，我似乎遇到链接器问题。未定义对Wt:: ..的引用。有什么建议吗？

使用msys shell，我编译了boost_1_69_0和wt4.0.5并在其他libwt.a和libwthttp.a中生成了lib。我将这些库移动到一个目录中，因为它们分散在不同的目录中。

我的hello.cc是来自：https://www.webtoolkit.eu/wt/doc/tutorial/wt.html

的简单程序

我正在尝试按以下方式构建它：

> g++ -std=c++14 -IC:/.../boost_1_69_0/include -LC:/.../boost_1_69_0/lib -IC:/.../wt4msys -IC:/.../wt4msys/src -LC:/.../wt4msys/lib -lwt -lwthttp hello.cc

但是我得到了以下大错误堆栈

还有什么可以尝试的，或者我在哪里犯错？
