title: Installing and using Emscripten
body: <p>I installed Emscripten through the steps shown below:</p>
  
  <pre><code>1.) Download the emsdk-portable version for Linux/MacOSX
  http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html#sdk-downloads
  2.)
  Run
  $ ./emsdk update
  $ ./emsdk install latest
  $ ./emsdk activate latest
  $ source emsdk_env.sh (To update your environment variables)
  </code></pre>
  
  <p>I  believe everything installed correctly, however I am unable to run emscripten anywhere outside of the emsdk folder.</p>
  
  <p>I need to be able to run em++ in my: Documents/project3/dataviz/graphiti folder.</p>
  
  <p>Also, when I run <strong><em>em++ -v</em></strong> in my emsdk folder, I get the following message I have been unable to resolve:</p>
  
  <pre><code>Java does not seem to exist, requierd for closure compiler,
  which is optional (define JAVA in /home/bryce/.emscripten if you want it) 
  </code></pre>
  
  <p>I attempted to define the java path in the folder, but I'm not sure how it should look.</p>
  
  <p>Any help resolving these two issues would be very much appreciated.</p>
