我已经在 Windows上构建了clang 3.2并且正在尝试构建一个简单的hello world程序.但是我收到了很多错误,如下所示.

我收到很多这样的错误,来自VC 2012标题.是否有可能在Windows上使用clang构建C 11代码？我是否必须提供额外的命令切换？

当由Visual Studio构建时,Clang无法正常工作(据说它可以在由MinGW构建时工作,但我无法自己验证).

构建Clang时,它被配置为使用用于构建它的库.由于您使用Visual Studio构建了Clang,因此Clang将尝试使用Visual Studio头文件和库.不幸的是,Clang和Visual Studio的内部结构不同,Clang无法使用特定于VS的标头.

直到libc++可以为Windows编译,Clang将(几乎可以肯定)在Visual Studio编译时不会工作.尝试使用MinGW构建它(并制作博客文章或者你如何做到这一点！),看看它是否适合你.
