Hi guys,
I'm looking to use in my Java application the face recognition features provided in the contrib modules but I'm facing a blocking issue : I can't manage to build the opencv_java310.dll.
I have read a lot and tried all that I could think about and today I'm requesting your help please.
In brief, the log file (opencv\build\modules\java\opencv_java.dir\Debug\opencv_java.log) after the build process fails show:
[...] face.cpp

My cmake log shows: -Python 3.4.4 64 bits -Ant 1.8.4 -Java jdk 1.7 64 bits
I'm building with Visual Studio 12 (2013)
Below are the changes I made in cmake:

- BUILD_opencv_bgsegm:BOOL=0

- BUILD_opencv_features2d:BOOL=0
- BUILD_DOCS:BOOL=0

- BUILD_opencv_optflow:BOOL=0
I have also tried to build contrib with the version 2.4.9 and 3.0 in case there was a compatibiliy issue but no luck.
Please let me know if you need any other information. That's my last hope I fear. Thanks.
