title: Renderscript samples build errors
body: <p>So I wanted to try out the samples that use RenderScript, and I imported HelloWorld in Eclipse. But it gives me errors like:</p>
  
  <pre><code>[2011-10-25 13:10:48 - HelloWorld] /home/mileoresko/workspace/utils/android-sdk-linux_86
  /platforms/android-11/renderscript/include/rs_graphics.rsh:240:58: error: unknown type 
  name 'float3'; did you mean 'float'?
  [2011-10-25 13:10:48 - HelloWorld] /home/mileoresko/workspace/utils/android-sdk-linux_86 
  /platforms/android-11/renderscript/include/rs_graphics.rsh:237:31: error: unknown type 
  name 'rs_mesh'
  </code></pre>
  
  <p>Also i noticed that the files that need to generate in the gen folder are missing?? (classes like ScriptC_helloworld).
  I've searched all morning for a solution but I was not able to find one. I updated the SDK and the ADT,  don't know what could be the problem. Please if someone had this problem and found/knows a solution, share it with me, am I desperate. I can not build any project from the samples. Thank u in advance!</p>
