title: Problems trying to compile in C with OpenCV
body: <p>I'm  trying to compile a C code with OpenCV in  ARM. When I try to compile, I'm using the next flags</p>
  
  <pre><code>-L/usr/lib
  -lpthread
  -lrt
  -l
  -I/usr/local/include/opencv
  -I/usr/local/include
  -L/usr/local/lib
  -lopencv_core
  -lopencv_imgproc
  -lopencv_highgui
  -lopencv_ml
  -lopencv_video
  -lopencv_features2d
  -lopencv_calib3d
  -lopencv_objdetect
  -lopencv_contrib
  -lopencv_legacy
  -lopencv_flann
  </code></pre>
  
  <p>and I get this error:</p>
  
  <pre><code>cannot find -lopencv_core
  cannot find -lopencv_imgproc
  cannot find -lopencv_flann
  </code></pre>
  
  <p>My <code>pkg-config</code> <code>--cflags</code> opencv: </p>
  
  <pre><code>-I/usr/local/include/opencv -I/usr/local/include  
  </code></pre>
  
  <p>and <code>pkg-config</code> <code>--libs</code> opencv:</p>
  
  <pre><code>-L/usr/local/lib -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_contrib -lopencv_legacy -lopencv_flann 
  </code></pre>
  
  <p>What's wrong here?
  Thanks in advance.</p>
