2016-11-01 07:43:13 -0500 answered a question error cross compiling for ARM

I found a workaround:

After running cmake and generating the make files, edit opencv/opencv/platforms/linux/<your_build_dir>/CMakeFiles/3.5.1/CMakeCCompiler.cmake and replace set(CMAKE_AR "CMAKE_AR-NOTFOUND") with set(CMAKE_AR "/usr/bin/arm-linux-gnueabi-ar")

Note that setting the variable CMAKE_AR in the cmake line (CMAKE_AR="/usr/bin/arm-linux-gnueabi-ar") does not work. Seems like this sets the flag to empty.

Delete the folder opencv/platforms/linux, recreate it and download the following files from https://github.com/opencv/opencv/tree/master/platforms/linux and put them inside /opencv/platforms/linux:

  • arm-gnueabi.toolchain.cmake
  • arm.toolchain.cmake
  • gnu.toolchain.cmake

Finally create your build folder inside /opencv/platforms/linux like instructed here, and you're good to go.

2016-10-30 11:21:04 -0500 asked a question Error while loading shared libraries: libopencv_highgui.so.3.1: internal error

I cross-compiled OpenCV for arm following this guide and built the sample program provided here.

When I run the program on my target I get the following error:

./DisplayImage: error while loading shared libraries:
lib/libopencv_highgui.so.3.1: internal error

What could be causing this?
