Thank you very much! But why it be removed? any concern?

Hi,

I found there's an openfabmap implementation in opencv 2.4
http://docs.opencv.org/2.4/modules/co...
but I cannot find the source code in official OpenCV repo (Itseez/opencv, opencv_contrib, opencv_attic)

Did I missed anything?

Thanks!

Hi,

I was trying to build my own OpenCV SDK for android-x86 platform. I've cloned the repo from https://github.com/Itseez/opencv , and set "opencv/platforms/android/android.toolchain.cmake" as CMake toolchain file.

And my environment is - Host: Ubuntu 14.04 x86_64 - Toolchain: android-ndk-r10e - CMake version: 3.2.2

And my target device is an x86 tablet which runs Android L.

The cmake command is as following

cmake \
-DANDROID_ABI=x86 \
-DCMAKE_TOOLCHAIN_FILE=$OPENCV_SRC_DIR/platforms/android/android.toolchain.cmake \
-DCMAKE_VERBOSE_MAKEFILE=OFF \
-DCMAKE_INSTALL_PREFIX=$OPENCV_INSTALL_DIR \
-DEIGEN_INCLUDE_PATH=$EXT_SRC_DIR/Eigen \
-DOPENCV_EXTRA_MODULES_PATH=$EXT_SRC_DIR/opencv_contrib/modules \
$OPENCV_SRC_DIR

However, the libraries I built can't work well, which always cause segmentation fault when any of OpenCV functions was invoked.

Would you please tell me how did you build the official OpenCV-3.1.0-android-sdk ? Because the official sdk libraries works very well on my device, I'd like to know the difference.

Please let me know if any further information is required.

Thanks.
