That supports the theory that you don't have a C compiler installed that dmd can use for preprocessing C files. Ali The [documentation](https://dlang.org/spec/importc.html#auto-cpp) says When compiling for Windows with the -m32mscoff or the -m64 switch, cl.exe /P /Zc:preprocessor will be used as the preprocessor. It might be useful for someone to add more information. I would certainly have no idea what that means if I tried to use Windows. Or perhaps stated better, I'd have no idea what I'm supposed to install or set up to get it to work.

Standard D programs don't need a C compiler; dmd is the D compiler. It needs a C compiler (to preprocess C sources) for ImportC. Ali

Problem with ImportC example?
This relates to the first example under 41.1 Quick Examples.

```
#include
int main()
{
printf("hello world\n");
return 0;
}
```
Produced:
