</span>Debian Linux is offering me the following packages<br>
libopencv-apps0d<br>
libopencv-calib3d2.4v5<br>
libopencv-contrib2.4v5<br>
libopencv-core2.4v5<br>
libopencv-features2d2.4v5<br>
libopencv-flann2.4v5<br>
libopencv-gpu2.4v5<br>
libopencv-highgui2.4-deb0<br>
libopencv-imgproc2.4v5<br>
libopencv-legacy2.4v5<br>
libopencv-ml2.4v5<br>
libopencv-objdetect2.4v5<br>
libopencv-ocl2.4v5<br>
libopencv-photo2.4v5<br>
libopencv-stitching2.4v5<br>
libopencv-superres2.4v5<br>
libopencv-ts2.4v5<br>
libopencv-video2.4v5<br>
libopencv-videostab2.4v5<br>
libopencv2.4-java<br>
libopencv2.4-jni<br>
which pulls in a total of 44 packages. I installed them all, loaded<br>
using [declare -lib pix_opencv] and can not create an object like<br>
[pix_opencv_threshold].<br>
<span class=""><br>

</span>No need on my side for now, thank you.<br>
How would apple users install and use pix_opencv by the way? You<br>
mentioned that you included a libopencv binary with the external?<br>

</span>Can you check which libopencv-packages you have installed on that<br>
computer?<br>

All the best,<br>
