Opencv: java module build failed

Created on 6 Nov 2015 · 3Comments · Source: opencv/opencv

Hi, I'm building opencv4android with opencv_contrib.
I cmake like this:
cmake -Wno-dev -DOPENCV_EXTRA_MODULES_PATH=/home/charles/Programs/opencv-3.0.0/opencv_contrib-3.0.0/modules -DCMAKE_BUILD_WITH_INSTALL_RPATH=ON -DCMAKE_TOOLCHAIN_FILE=../android/android.toolchain.cmake
!================================================================
The outputs of cmake is here:
https://gist.github.com/happycharleswang/345a21b4db88141980fe
!================================================================

I got this error when make -j8

1) It is opencv_contrib related, so right place is here: https://github.com/Itseez/opencv_contrib/issues
2) Looks like there is incorrect tesseract detection in cross-compilation mode.
3) Workaround for this is to disable "text" module: -DBUILD_opencv_text=OFF

Thanks.

-DBUILD_opencv_java=OFF works.

-DBUILD_opencv_text=OFF also works.

This means both java module and text module are related to this issue.
