Windows.h和铛（LLVM）

Question

我想编译一个包含windows.h使用铛编译器的小项目。不幸的是，clang产生了一些我无法解决的错误。什么导致这些错误？锵不支持所有必需的功能，我错过了什么？

您可能需要定义UNREFERENCED_PARAMETER宏的铿锵兼容版本。像这样的东西应该可以帮助你：http://sourcefrog.net/weblog/software/languages/C/unused.html

此外，看起来类型LONGLONG被定义为clang的double类型，并且你不能在浮点数上执行二进制算术（和，或不等）。您需要确保这是typedefed作为一个适当的整数类型。

根据关于如何构建windows.h，winbase.h和winnt.h的一些信息，您可以使自己的包装器得到正确的定义以实现此传递。否则，尝试找到一个与gcc兼容的windows.h版本，并使用它。 Clang应该与它兼容。

祝你好运！
