Don't forget the Windows SDK!

[retep998]

So many people encounter issues with Rust not working because they forgot this crucial bit.

Thanks - do you know which parts of the windows SDK are actually required? It seems like I can build and run programs just fine without the windows SDK if I bypass the check here...

@Diggsey How are you able to build programs without the Windows SDK? Any program that targets pc-windows-msvc relies on the import libraries provided by the Windows SDK in order to be linked. How else are you getting kernel32.lib if not somewhere in C:\Program Files (x86)\Windows Kits\10\Lib?

I found I only needed the Universal CRT to build a basic hello world.

(Specifically C:\Program Files (x86)\Windows Kits\10\Lib\10.0.15063.0\ucrt\x64\ucrt.lib)

This is the linker invocation used to build my program (spaced out for ease of reading):

Not sure where or if it is getting those libraries, as I moved out everything except ucrt.lib.

@Diggsey Are you sure you're not pulling in perhaps stuff from C:\Program Files (x86)\Windows Kits\8.1\Lib? What does your LIB environment variable have? advapi32.lib is one of those libraries that you have to get some version of the Windows SDK in order to get.
