Building all the libraries on the Raspberry Pi
I installed the OpenCV on my Raspberry Pi, however I'm receiving some error messages when I do the command :"./build_all.sh" in the Opencv/samples/c folder:

I looked for these files, and they are in the paths:
/home/pi/opencv/modules/core/include/opencv2/
/usr/local -D/include/opencv2/
How can I make for it to find these libraries? I think that the opencv in looking for ...
/usr/local -D/include/opencv2/ <-- what's the weird -D doing in there ?
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 ..
Already solved, I just copied the files from "local -D" to "local" and it's working now!
Thanks!
