Build the Opencv-2.4.5 For CARMA Issue

Question

I have successfully Done Cmake with following option.

$cmake -DGCC_COMPILER_VERSION=\"4.5\" -DSOFTFP=ON -DUSE_NEON=ON -DCMAKE_SKIP_RPATH=ON -DCUDA_TOOLKIT_ROOT_D         


        

Answer 1

It seems like you are using old version of CMake.

Cross-compilation with CUDA requires at least 2.8.10 CMake version. It is not available in Ubuntu repository.

Please download the latest CMake from their website: http://www.cmake.org/cmake/resources/software.html

Here is instruction for CARMA compilation: http://code.opencv.org/projects/opencv/wiki/CARMA_platform_compilation_and_testing

GTK Support

OpenCV can be compiled with UI support using GTK back-end.

• Install GTK on target device.

  apt-get install libgtk2.0-dev

• Install GTK on host (for required header files).

  apt-get install libgtk2.0-dev

• Copy /lib/arm-linux-gnueabi and /usr/lib/arm-linux-gnueabi folders from target to host to the same location.

• In addition to the two directories above, copy all files from /usr/lib on target to the /usr/lib/arm-linux-gnueabi on host machine.

• Install pkg-config-arm-linux-gnueabi package on host.

  apt-get install pkg-config-arm-linux-gnueabi

• Add next parameters to cmake command line:

  -DPKG_CONFIG_EXECUTABLE=/usr/bin/arm-linux-gnueabi-pkg-config -DWITH_GTK=ON
