title: Android NDK. No C/C++ section in Eclipse project properties
body: <p>I am trying to follow the instructions specified <a href="http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/O4A_SDK.html" rel="nofollow">here</a> to install OpenCV for Wlipse.</p>
  
  <p>The instructions state:</p>
  
  <p>Open Project Properties -> C/C++ Build, and replace “Build command” text to "${NDKROOT}/ndk-build"</p>
  
  <p>However, if I open my Project Properties I have no C/C++ section.</p>
  
  <p>I am using Android SDK ADT Bundle for OSX</p>
  
  <p>I have downloaded the NDK</p>
  
  <p>I have set the NDK location under ADT->Properties->Android->NDK</p>
  
  <p>I have validated that the Android Native Dev Tools and C/C++ Dev Tools are installed</p>
  
  <p>I have imported the project correctly</p>
  
  <p>Why don't I have a C/C++ section under Project->Properties</p>
  
  <p><strong>Next problem.</strong></p>
  
  <p>Ok I have found how to add the c/c++ build command thanks to srikanth gr</p>
  
  <p>Now when i try and build the OpenCV Library I get the following error</p>
  
  <p>OpenCV.mk: No such file or directory</p>
  
  <p>the current reference in the jni/Android.mk is </p>
  
  <p>include OpenCV.mk</p>
  
  <p>I did a search on my system and no OpenCV.mk file exists. There is a OpenCV.mk.in. Do i need to build that to create the OpenCV.mk? If so how?</p>
  
  <p>Thanks</p>
