Hey guys! I'm facing some trouble installing 3.2.0 on my pi3. I'm new to linux. I followed the steps here: pklab(dot)net/?id=392&lang=EN

but the build would always return errors no matter what I tried. I checked my version of gcc as the problem seemed to be C++ related(? not sure). I've tried googling the errors in different ways but I'm unable to find a solution.

Edit:Here's the entire build as seen on the kernel:

@berak I have edited the post to include the whole build log as seen on my kernel

and also, I have copied the cmake error log to a pastebin: pastebin(dot)com/FP1MA1Ji

one error is here

No extra modules found in folder:
/home/pi/opencv/opencv-3.2.0/build/opencv/opencv_contrib-3.2.0/modules

Please provide path to 'opencv_contrib/modules' folder.
Call Stack (most recent call first):
 modules/CMakeLists.txt:7 (ocv_glob_modules)

is path correct?

LBerger gravatar imageLBerger ( 2017-03-21 10:49:37 -0500 )edit

@LBerger In the cmake command I entered the following path, -D OPENCV_EXTRA_MODULES_PATH=opencv/opencv_contrib-3.2.0/modules

That path is correct both opencv-3.2.0 and opencv_contrib-3.2.0 are inside directory "opencv"

Can you try without opencv_contrib first?

LBerger gravatar imageLBerger ( 2017-03-21 11:00:39 -0500 )edit

@Lindsay98 the correct path to contrib would be:

OPENCV_EXTRA_MODULES_PATH=/home/pi/opencv/opencv_contrib-3.2.0/modules

Ok I've checked the tutorial and it looks correct. BTW you should use right path for contrib modules absolute or relative path. Maybe you mistype the / at the beginning or you can try with relative path such as -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-3.2.0/modules. Thank you to @LBerger

@LBerger Tried it without the contrib and it worked!!

Tried it with both @berak 's OPENCV_EXTRA_MODULES_PATH=/home/pi/opencv/opencv_contrib-3.2.0/modules and @pklab 's updated path and it doesn't work

So i guess, it's the contrib path.. any ideas? tried renaming the contrib directory to opencv_contrib, it still doesn't work.. I should have tried it without the contrib at the beginning when I started debugging. Rookie mistake.

Thank you guys so much @LBerger , @pklab and @berak

100%, the path is still wrong. last attempt: cd into your opencv_contrib/modules folder, and try a pwd

(i'm almost sure, that this will lead to some 'omg, previous assumptions were all wrong' moment)
