How to cross-compile opencv

I'm trying (with no success) to cross-compile OpenCV on a embedded board. I followed this: http://docs.opencv.org/doc/tutorials/introduction/crosscompilation/arm_crosscompile_with_cmake.html.

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.

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?

Alternative approach

Just take some embedded distro like Buildroot, OpenEmbedded or Debian. They all provide OpenCV.

As I'm mostly experienced in Buildroot, I'd like to point to the newly introduced feature to keep your project separate from BR: http://nightly.buildroot.org/manual.html#outside-br-custom. This will give you a main idea on how to compile your software against BR's OpenCV.
