将静态窗口库转换为dll

我不知道anyb会自动执行此操作的工具，但该过程是创建一个DLL项目并将您的库添加到项目。 对于头文件中的每个函数：

 int SomeLibFunc( int x, int y ); 

你需要在DLL中创建和导出你自己的函数;

 int MyFunc( int x, int y ) { return SomLibFunc( x, y ); } 

这个过程是非常机械的，你可以用Perl之类的东西来创建DLL源文件。

假设你没有访问源，你可以简单地创建一个包装DLL，导出你需要的功能并委托给静态库。

我做了一个建议，我做了一个自动转换器（有人建议只是把_ddlspec（导出）之前宣布和编译dll这个头将工作 – 以及它没有 – 也许我做错了事 – 我是平原旧Java程序员;））：

它基本上解析头文件，并转向：

  SADENTRY SadLoadedMidFiles( HMEM, USHORT usMaxMidFiles, VOID * ); 

至：

  __declspec(dllexport) SADENTRY DLL_WRAPPER_SadLoadedMidFiles(HMEM param0, USHORT usMaxMidFiles, VOID* param2){ return SadLoadedMidFiles(param0, usMaxMidFiles, param2); } 

这里是代码（很可能是它的正则表达式滥用，但它的工作原理），贵部分取决于MigLayout：
