title: Eclipse can't include opencv2 header files
body: <p>I've created an Android Application Project in Eclipse Juno, and after I've added native support to this project (Android Tools -> Add Native Support). So Eclipse has added in the project automatically a jni directory, within which a .cpp file and the file Android.mk.</p>
  
  <p>Then I've build the project, without errors. </p>
  
  <p>In order to use opencv for android libraries (2.4.5), I've added the path to the 'include' directory of these libraries in the project (Properties -> C/C++ General -> Path And Symbols -> Include Diretories). I've also set in the Eclipse Preferences -> NDK the correct path to the ndk directory in my pc, to make possible to execute ndk-build when I build the projects.</p>
  
  <p>But, if i try to include in the .cpp file:</p>
  
  <pre><code>#include &lt;opencv2/opencv.hpp&gt;
  </code></pre>
  
  <p>The console show me this result:</p>
  
  <pre><code>12:24:25 **** Build of configuration Default for project ProvaVideoCapture ****
  "C:\\Users\\Micaela\\Desktop\\Android\\android-ndk-r8e\\ndk-build.cmd" all

  compilation terminated.
  make: *** [obj/local/armeabi-v7a/objs/jniVideoCapture/jniVideoCapture.o] Error 1
  
  12:24:26 Build Finished (took 282ms)
  </code></pre>
  
  <p>My Android.mk file is:</p>
  
  <pre><code>LOCAL_PATH := $(call my-dir)
  
  include $(CLEAR_VARS)
  
  LOCAL_MODULE    := jniVideoCapture
  LOCAL_SRC_FILES := jniVideoCapture.cpp
  
  
  include $(BUILD_SHARED_LIBRARY)
  </code></pre>
  
  <p>The Application.mk file that I've added manually (it has not been automatically added by Eclipse) is:</p>
  
  <pre><code>APP_ABI := all
  APP_STL := gnustl_static
  APP_CPPFLAGS := -frtti -fexceptions
  APP_PLATFORM := android-9
  </code></pre>
  
  <p>I don't know how to solve this problem, or what I've done wrong.</p>
  
  <p>Could you help me?</p>
