title: How to cross-compile opencv
body: <p>I'm trying (with no success) to cross-compile OpenCV on a embedded board.
  I followed this: <a href="http://docs.opencv.org/doc/tutorials/introduction/crosscompilation/arm_crosscompile_with_cmake.html" rel="nofollow">http://docs.opencv.org/doc/tutorials/introduction/crosscompilation/arm_crosscompile_with_cmake.html</a>.</p>
  
  <p>To summarize I installed the cross compilation tools for ARM, the I ran the cmake (providing the proper toolchain file), the make and the make install commands.
  I next copied the lib/ include and bin/ directories with the opencv installation in the embedded board.</p>
  
  <p>However, when I try to compile a simple hello world with opencv I get undefined reference to __gnu_thumb1_case_uqi and other similar symbols.
  Does anybody faced this problem and know how to solve it?</p>
