Compiling LuaSocket: Cannot open file: 'string.h'

The log:

C:\WINDOWS\system32>luarocks install luasocket
Installing https://luarocks.org/luasocket-3.0rc1-2.src.rock...
Using https://luarocks.org/luasocket-3.0rc1-2.src.rock... switching to 'build' mode

mime.c
src/mime.c(5): fatal error C1083: Cannot open include file: 'string.h': No such file or directory

Error: Build error: Failed compiling object src/mime.obj

I'm very new to the whole LuaRocks thing, so I have no idea how to go about fixing this.

Here's a non-complete guide to get you started on installing lua modules from a fresh Windows 7.

1) We need LuaRocks in order to install Lua dependencies automatically (similar to cpan/cpanm in Perl or pip in Python). Download LuaRocks by grabbing the latest version with a "-win32.zip" suffix from here: http://keplerproject.github.io/luarocks/releases/

At the time of this writing, this is the following file: http://keplerproject.github.io/luarocks/releases/luarocks-2.3.0-win32.zip

2) Unzip it into a new directory and install it with install.bat /L. Without the "/L" flag, it will complain that it cannot find your existing Lua installation. With the flag, it will just install a new Lua binary (version 5.1). LuaRocks is now installed to C:\Program Files (x86)\LuaRocks. You may now delete the extracted "luarocks-2.3.0-win32" directory.

3) In order to compile and install modules, we will need a C++ compiler. Download and install the Visual C++ Build Tools 2015 from here: http://landinghub.visualstudio.com/visual-cpp-build-tools

(We want this so that we can avoiding installing the huge, multi-gigabyte Visual Studio 2015.)

4) Navigate to C:\Program Files (x86)\Microsoft Visual C++ Build Tools. Right click on "Visual C++ 2015 x86 Native Build Tools Command Prompt", and select "Run as administrator".

5) Run the following command: "C:\Program Files (x86)\LuaRocks\luarocks.bat" install luasocket.

Note that you may have to install additional stuff for certain modules. And sometimes, modules are simply unable to be compiled on Windows at all.
