Hello,

I encountered really strange issue, which appeared recently most likely due to XCode/Java updates. Here is my setup:

  • OSX EL Capitan 10.11.6
  • Xcode Version 8.1 (8B62)
  • java version "1.8.0_111"
  • Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
  • Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)

My codebase is: commit 6c12533160bc5e6de1f09847d9cd6dd548667a55 Merge: 811eb76 bec3479 Author: Alexander Alekhin alexander.a.alekhin@gmail.com Date: Mon Oct 31 17:35:41 2016 +0000

Previously I was able to build opencv master from sources with no issues but when I'm trying to build it now, it cannot find jni.h!:

/opencv/modules/java/generator/src/cpp/common.h:8:10: fatal error: 'jni.h' file not found
#include <jni.h>

Appreciate any ideas or hints how to fix this? JAVA_HOME is pointing at correct folder and also include folder is there and jni.h is where it should be ...

Found the answer. For some reason the path to old JDK was preserved in the cmake settings so it was pointing to non-existing folder. Here is the fix:

  1. run ccmake .. in opencv/build folder
  2. toggle advanced mode (press 't')
  3. found and changed JNI paths.

This is just in case if anybody will face the similar problem after upgrade of xcode/jdk.
