Emscripten On OSX | GameDev.net

Did you see that the Epic Citadel demo now runs at full speed under Chrome as well (http://www.unrealengine.com/html5/)?

This got me curious about emscripten once again, and so I set it up on my mac. Actually very straight forward, but not a one-liner:

install brew if you don't have it (if you're using macports, then you are on your own :-)
always good to update brew: brew update && brew outdated
[font=arial][background=transparent]brew install node spidermonkey closure-compiler yuicompressor[/background][/font]
1. [font=arial][background=transparent]?[/background][background=transparent]Of course, you can leave out any you already have installed (fx. I already had node and closure-compiler)[/background][/font]
[font=arial][background=transparent]brew install llvm --with-clang[/background][/font]
brew tap homebrew/versions
brew install llvm33
create symlinks to llvm33:
1. cd /usr/bin
2. sudo ln /usr/local/Cellar/llvm33/3.3/bin/opt-3.3 opt
3. sudo ln /usr/local/Cellar/llvm33/3.3/bin/llvm-as-3.3 llvm-as
4. sudo ln /usr/local/Cellar/llvm33/3.3/bin/llvm-dis-3.3 llvm-dis
5. sudo ln /usr/local/Cellar/llvm33/3.3/bin/llvm-nm-3.3 llvm-nm
6. sudo ln /usr/local/Cellar/llvm33/3.3/bin/lli-3.3 lli
7. sudo ln /usr/local/Cellar/llvm33/3.3/bin/llvm-link-3.3 llvm-link
8. sudo ln /usr/local/Cellar/llvm33/3.3/bin/llvm-ar-3.3 llvm-ar
9. sudo ln opt /usr/local/Cellar/llvm33/3.3/bin/ocpt-3.3
10. (you get the idea, basically emscripten will tell you if you forgot one)
setup Python:
1. cd /usr/bin
2. sudo ln python python2
3. sudo ln ../../System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 python22.7
setup emscripten:
1. cd ~
2. git clone https://github.com/kripken/emscripten.git
3. cd emscripten
4. ./em++ --help
try it out:
1. ./emcc tests/hello_world_gles.c -o hello_world_gles.html
2. open hello_world_gles.html

When the browser open the html file, it should display this scene:

And it is only 200k of js! Amazing :-P

Mkkl.

PS! I don't have access to IE11 yet, exciting times if it actually works!
