Dear all,
I just compiled Opencv-3.0.0 from the source code on Github with the following options:
I'm running on Redhat 6.6.
mkdir build
cd build
cmake -D WITH_PTHREADS_PF=OFF -D WITH_OPENMP=ON -D WITH_IPP=OFF -DBUILD_SHARED_LIBS=OFF -D CMAKE_INSTALL_PREFIX=. ../
make -j8
Things seem to go well and the ant build also succeeds. In my build/lib directory I have a splendid 15 megabyte libopencv_java300.so, and in my build/bin directory a very lovely opencv-300.jar.
In order to test things out I've been using my Scala console. Here's the short program that I execute in the read-eval-print-loop:
[me@home lib]$ LD_LIBRARY_PATH=. scala -classpath ../bin/opencv-300.jar

OpenCV 2.4.11 works wonderfully, but I was hoping to take advantage of a few of the improvements in 3.0.0, such as the new FeatureDescriptors and some of the improved Java API. Unfortunately, I haven't been able to get to the bottom of the UnsatisfiedLinkError. I would greatly appreciate any advice!
