how did you install opencv ?

(opencv_imgcodecs was not loaded because jpeg is missing / wrong version)

this means, now you have a different set of jpg/tiff libs, than your opencv libs were built with

again, try to rebuild opencv from src.

Sir how can i do it i see all steps of installation from http://docs.opencv.org/2.4/doc/tutori...

@boom gravatar image@boom ( 2016-08-17 00:50:40 -0600 )edit

please use opencv3 docs , not the 2.4 ones !

try to rebuild the opencv libs with

cmake -DBUILD_JPEG=ON -DBUILD_TIFF=ON -DBUILD_PNG=ON

so it's using the 3rd party libs that come with opencv, not your system libs.

Or make sure that before running the cmake, you install all prerequisites for OpenCV as described here.

cmake -DBUILD_JPEG -DBUILD_TIFF -DBUILD_PNG Parse error in command line argument: -DBUILD_JPEG Should be: VAR:type=value CMake Error: No cmake script provided. CMake Error: Problem processing arguments. Aborting.

apologies, it has to be -DBUILD_JPEG=ON, etc. please see edit above.

Yes command run correct but again no change in o/p while compiling the code. In opencv docs there is command but when i run it Here is the error. CMake Error: The source directory "/home/sachin/Desktop/pics" does not appear to contain CMakeLists.txt. Specify --help for usage, or press the help button on the CMake GUI. THIS IS THE COMMAND cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/home/sachin/opencv /home/sachin/opencv is the folder path and /usr/local/include/opencv2 is my library path

@boom gravatar image@boom ( 2016-08-17 01:13:52 -0600 )edit

last (missing) argument to the cmake cmdline should be the opencv src folder (where CmakeLists.txt is)
