我移植了最初为UNIX环境编写的PHP扩展的源代码。
我已经解决了所有库依赖项并成功编译了它，但是我们用于测试的EasyPHP服务器拒绝加载DLL模块。
我已经假设了，因为我已经使用Visual Studio 2015（v140）平台工具集编译了DLL，而据我所知，服务器使用v11源的原始PHP。
但是，将项目从v140更改为Visual Studio 2012（v110）工具集会产生以下错误：
LNK1120 5 unresolved externals DINAPIS_PHP_MATH

正如你所看到的，这个＆＃34; jansson＆＃34;库产生了所有问题，并且让我头痛原始移植。
那么什么是v110工具集缺少产生这些错误，当v140编译好？怎么解决？
谢谢！
