2014-06-20 06:04:27 -0600	asked a question	Error while building OpenCV on Raspberry PI I'm having some problems on the OpenCV installation, I've been following this tutorial https://docs.google.com/document/d/1bgVo24hCK0huoxm9zGC9djL6K0yy0z9GldzSy6SZUQY/pub, however when I'm compiling it I receive an error message: pi@raspberrypi ~/opencv/build $ make [ 0%] Built target

2014-06-12 06:29:22 -0600	asked a question	Facedetect not working from Camera Hi, I'm trying to use the camera on my Raspberry Pi to make face detection, however it's not working. The camera is working normally, but not for face detection, and the face detection works normally but with images. I'm receiving this message: "Capture from CAM 0 didn't work In image read" Any suggestions? Thanks
2014-06-12 05:06:26 -0600	commented question	Building all the libraries on the Raspberry Pi Already solved, I just copied the files from "local -D" to "local" and it's working now! Thanks!
2014-06-11 05:52:40 -0600	commented question	Building all the libraries on the Raspberry Pi Good question, this folder just appeared, I was think it could be normal. I have both "/usr/local/" and "/usr/local -D/", I checked the content of these folders and they are different. So probrably the OpenCV is looking for the libraries inside "/usr/local/" and is actually in "/usr/local -D/". Is that it? Maybe when I executed this command, cmake created a folder with this name: cmake -D CMAKE_BUILD_TYPE=RELEASE -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_OPENGL=ON ..
