明w-x64中的类型错误

Question

我正试图在windows上构建我的项目(wpilib)，它来自linux，它在那里工作得很好。我安装了mingw，但它似乎没有我所使用的所有线程，所以我删除了它并安装了mingw-x64。这让我更进一步，但现在我被困在这里了。

Answer 1

由于某种原因，在我的所有.cpp文件中添加以下内容似乎解决了这个特定的问题。我注意到每个人似乎都把它放在最上面，但我看不出它和UINT_PTR之间的联系，后者是在basetsd.h中定义的

#ifdef _WIN32
  // Ensure that Winsock2.h is included before Windows.h
  #include <Winsock2.h>
#endif

如果有人知道这是为什么，我很想知道
