I installed Oracle Java from WebUpd8 and am trying to get OpenCV working according to these instructions.

$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install -y oracle-java7-installer oracle-java7-set-default build-essential cmake
$ sudo update-java-alternatives -s java-7-oracle
$ cd opencv/build
$ cmake -DBUILD_SHARED_LIBS=OFF ..
$ make
$ scala -cp /home/parallels/opencv/build/bin/opencv-248.jar -Djava.library.path=/home/parallels/opencv/build/lib
scala> import org.opencv.core._
scala> System.loadLibrary(Core.NATIVE_LIBRARY_NAME)
scala> val m:Mat = Mat.eye(3,3,CvType.CV_8UC1)

As far as I can tell, this is correct, but I keep running into the following error:

java.lang.UnsatisfiedLinkError: org.opencv.core.Mat.n_eye(III)J

What could be causing this? How do I remedy this?

I'm working on an OpenCV project, and it works as intended, but it fills my console with annoying warnings. For example:

VIDIOC_QUERYMENU: Invalid argument
VIDIOC_QUERYMENU: Invalid argument
HIGHGUI ERROR: V4L: index 2 is not correct!

Is there any way within the API to suppress these, or would I have to recompile OpenCV?
