I encountered the problem during compiling OpenCV. Error message said that I don't have Eigen. However, I do have one in my /usr/local/include directory. Also, I ran CMake with option below.
CMake:
cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D CUDA_GENERATION=Auto USE_EIGEN=/usr/local/include/Eigen ..

Does anyone have any idea about this? Thanks!!
Building it with -DWITH_EIGEN=OFF solved the issue for me.
here cmake is unable to find unsupported/Eigen/MatrixFunctions. First find where Eigen is installed, in my case it was located at /usr/local/include/eigen3. Now locate your rgbdodometry.cpp file, in my case it was in /opencv_contrib/modules/rgbd/src. Open the cpp file and modify the previous line with something like
"/usr/local/include/eigen3/unsupported/Eigen/MatrixFunctions"

I am trying to build opencv on macOS for a CPP capstone project but when I try to compile like so:
cmake -D CMAKE_BUILD_TYPE=RELEASE -DBUILD_SHARED_LIBS=OFF -D BUILD_opencv_objdetect=OFF -D BUILD_opencv_video=OFF -D BUILD_opencv_videoio=OFF -D BUILD_opencv_features2d=OFF -D BUILD_opencv_flann=OFF -D BUILD_opencv_highgui=OFF -D BUILD_opencv_ml=OFF -D BUILD_opencv_photo=OFF -D BUILD_opencv_python=OFF -D BUILD_opencv_shape=OFF -D BUILD_opencv_stitching=OFF -D BUILD_opencv_superres=OFF -D BUILD_opencv_ts=OFF -D BUILD_opencv_videostab=OFF ..
make -j8
I am getting the following error:

Any help is highly appreciated.
I installed OpenCV 4.1 on Ubuntu 18.04 LTS. The problem is when I compile my project's CMake file, the output is:
/usr/bin/ld: cannot find -lopencv_nonfree
collect2: error: ld returned 1 exit status

make: *** [all] Error 2
My CMake flags when I compile OpenCV are:
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D WITH_TBB=ON -D WITH_V4L=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D BUILD_EXAMPLES=ON -D OPENCV_GENERATE_PKGCONFIG=YES -D OPENCV_ENABLE_NONFREE=ON -D WITH_OPENMP=ON -D WITH_OPENCL=ON -D INSTALL_CREATE_DISTRIB=ON -DBUILD_opencv_world=OFF -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules ..
Can someone help me?
Dear stackoverflow users,
I'm trying to compile kate from source but I'm getting an error with a not declared variable.
So far these are the commands I'm using:
#! /bin/bash
cmake \
-D CMAKE_BUILD_TYPE=RelWithDebInfo \
-D CMAKE_INSTALL_PREFIX=~/kde/usr \
-D KDE_INSTALL_USE_QT_SYS_PATHS:BOOL=ON \
-D TARGET_include_directories:PATH="/usr/include/x86_64-linux-gnu/qt5/" \
-D Qt5_INCLUDE_DIRS:PATH="/usr/include/x86_64-linux-gnu/qt5/" \
-D Qt5_LIBRARY_DIRS:PATH="/usr/lib/x86_64-linux-gnu/qt5/" \
../kate/
make
make install
Please find below the error during compiling: I think it has to be related with not including some path file that should be there which declares the variable QWidgetAction, however I'm not sure why, since I installed all required packages as per the website.
(qtbase5-dev qtscript5-dev extra-cmake-modules plasma-framework-dev libkf5crash-dev libkf5config-dev libkf5activities-dev kinit-dev kdoctools-dev libkf5i18n-dev libkf5parts-dev libkf5guiaddons-dev libkf5iconthemes-dev libkf5jobwidgets-dev kio-dev libkf5texteditor-dev libkf5windowsystem-dev libkf5xmlgui-dev libgit2-dev).
The reason I'm compiling it is because I messed up with my original installed kate and I just can't load back all plugins, since my /.config kate folder is gone. Please any help is appreciated.

QWidgetAction is a part of Qt. Have you got the Qt libraries and headers properly in your path?
Header: #include
The same error first occured in the middle of the build when linking another shared library. Then I've added BUILD_SHARED_LIBS=OFF so now it occurs at the very end only. The last two options were also added in hope of fixing it. Using LinuxMint 17.

It is ffmpeg which should have been compiled with -fPIC. enter link description here I had ffmpeg compiled from sources. After deinstallation, opencv links fine.
I'm trying to build OpenCV on Ubuntu 15.10 with opencv_contrib (to use the nonfree modules). I did the following:
cmake -D CMAKE_BUILD_TYPE=RELEASE -DOPENCV_EXTRA_MODULES_PATH=/home/myname/Downloads/opencv_contrib-master/modules -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=OFF -D WITH_OPENGL=ON -D BUILD_opencv_ximgproc=ON ..
but I tried also with
BUILD_opencv_ximgproc=OFF
CMake goes well but it fails during the make step:
CMakeFiles/Makefile2:8403: recipe for target 'modules/xphoto/CMakeFiles/opencv_xphoto.dir/all' failed
make[1]: *** [modules/xphoto/CMakeFiles/opencv_xphoto.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....
and then:
Makefile:136: recipe for target 'all' failed
make: *** [all] Error 2
Do you have any suggestions?
Thanks.
I solved it by deleting and re-downloading both opencv and opencv_contrib. Then I built everything again:
git clone https://github.com/Itseez/opencv.git
git clone https://github.com/Itseez/opencv_contrib.git
cd opencv
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE -DOPENCV_EXTRA_MODULES_PATH=/home/myname/Downloads/opencv_contrib/modules -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=OFF -D WITH_OPENGL=ON -D BUILD_opencv_ximgproc=ON ..
make -j7
sudo make install
