Can not find Java folder in OpenCV build
I have built OpenCV for android on Windows using CMAKE, MINGW and NVIDIA Android NDK.
After I make it and make install it, I found the following folders:
install:
-apk:
-sdk:
--etc
--native
there is no java folder inside the sdk folder. libopencv_java3.so is also mssing. What did I miss?
EDIT (CMake output):
Detected version of GNU GCC: 49 (409)
FP16: Compiler support is available
Could NOT find Doxygen (missing: DOXYGEN_EXECUTABLE)
To enable PlantUML support, set PLANTUML_JAR environment variable or pass -DPLANTUML_JAR=<filepath> option to cmake
Could NOT find PythonInterp: Found unsuitable version "2.7.13", but required is at least "3.4" (found C:/Python27/python.exe)
Could NOT find PythonInterp: Found unsuitable version "2.7.13", but required is at least "3.2" (found C:/Python27/python.exe)
Found apache ant 1.8.2: C:/NVPACK/apache-ant-1.8.2/bin/ant.bat
Assume that non-module dependency is available: z (for module opencv_core)
[OpenCV for Android SDK]: A new OpenGL Camera Bridge (CameraGLSurfaceView, CameraGLRendererBase, CameraRenderer, Camera2Renderer) is disabled, because ANDROID_SDK_TARGET (15) < 21
Sample example-tutorial-4-opencl is disabled, because ANDROID_OPENCL_SDK is not specified

can we see your cmake output ?
@berak Thanks.. I have added them
hey, thanks, but that's a directory listing, not the console-log from running cmake.
(theory is, that it is missing something, and thus did not build the java wrappers)
it seems that you are right : Java: ant: C:/NVPACK/apache-ant-1.8.2/bin/ant.bat (ver 1.8.2) Java wrappers: NO Java tests: NO
so it found ant (that's good !)
do you have python ? (needed to generate the java code)
(i'm sure, there's more hints in that log, so maybe add it to question (yes, it's long!))
yes i do not have python and I am going to add that log right now.. thank you very much for your time
Oh! adding python solves the problem and the new log contains java wrapper... thank you again :)
now, don't tell me, it's solved, now .. (there's usually more than 1 problem) ,]
or, is it ?
@berak.. it failed when compiling :/ I thought that it was solved when cmake operation succeeded. I have edited with the cmake output. many thanks
