Instructions for installing Emscripten (based on Windows), assuming you are following directions here: http://asquera.de/blog/2017-04-10/the-path-to-rust-on-the-web/, to get Rustup and the right target installed.
- Navigate here, http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html, and download 64-bit Emscripten SDK for Windows.
- Ensure that you have the required dependencies on your system: https://kripken.github.io/emscripten-site/docs/building_from_source/building_emscripten_from_source_on_windows.html#installing-required-tools
- Please note that Fastcomp is installed for you with the Windows SDK, so don't worry about that one.
- Just focus on making sure you have
Python,Node.JS,Visual Studio 2015(not 2010),Cmake, and Java - Lastly, you don't need to clone the repo as you will install via the Windows SDK
- Unzip and place files wherever makes most sense on your system, it doesn't matter
- Make sure Microsoft Visual Studio 2015 is installed
- Navigate to the directory where you placed unzipped files
- Execute
emcmdprompt.batto start a command prompt - Run
emsdk update - Run
emsdk install sdk-incoming-64bit --vs2015 - Run
emsdk activate sdk-incoming-64bit - In the same command prompt you should be able to run
emcc -vand see the version output
In this directory where you've cloned this repo:
- In
.cargo/config, most likely located atC:\Users\<username>place the following in the file:
[target.wasm32-unknown-emscripten]
linker = "C:\\Users\\<username>\\path\\to\\emscripten\\<emscripten version number>\\emcc.bat"
- Run
rustup target add wasm32-unknown-emscripten - I'm using Rust nightly, not sure you need it though, try stable out
- Run
cargo build --target=wasm32-unknown-emscripten --release - Run
npm install - Run
npm run gulp - Navigate to
http://localhost:3006/in SAFE browser - If navigating to
localhost://p:3006you'll observe an error in console that Fetch API failed due to localhost URL scheme not being supported. Looking into it...
