How to use rust-mozjs on Windows?

[ctaggart]

I took a look at the examples/callback.rs and I would like to try using rust-mozjs, but I'm not sure how to. Any plans to create a crate?

I was under the impression that I need to build SpiderMonkey on my PC. On this PC, I'm running Windows 8.1 and I'm not that familiar with make or mozmake. Here is a recap of what I've done so far:

cd c:\rust
git clone https://github.com/mozilla/gecko-dev.git --depth 1

Downloaded MozillaBuild 2.0.0 and extracted to c:\rust\mozilla-build. I have Visual Studio 2015 installed, so I launched the build environment c:\rust\mozilla-build\start-shell-msvc2015-x64.bat. In it, I did:

cd /c/rust/gecko-dev
mkdir build_OPT.OBJ
cd build_OPT.OBJ
../configure --target=x86_64-pc-mingw32 --host=x86_64-pc-mingw32 --enable-nspr-build
mozmake

How do I get a list of mozmake targets? How do I get it to build?

Here is `../configure --help' output:

rust-mozjs works specifically with https://github.com/servo/mozjs which should both be usable from any cargo-using project like so:

[dependencies.js]
git = "https://github.com/servo/rust-mozjs"

[ctaggart]

That looks much easier! I'll give that a shot.

@ctaggart you got success using rust-mozjs in windows?
