fatal error: Eigen/Eigenvalues in ubuntu

Question

Currently, I am trying to install opencv3.0 on my ubuntu machine but I am getting an error message when I type the make command.

This is my error message:

/home/innovation/opencv-3.0.0/modules/calib3d/src/dls.cpp:11:31: fatal error: Eigen/Eigenvalues: No such file or directory
#  include <Eigen/Eigenvalues>
                           ^
compilation terminated.
make[2]: *** [modules/calib3d/CMakeFiles/opencv_calib3d.dir /src/dls.cpp.o] Error 1
make[1]: *** [modules/calib3d/CMakeFiles/opencv_calib3d.dir/all] Error 2
make: *** [all] Error 2

this is the cmake code:

cmake -D CMAKE_BUILD_TYPE=RELEASE -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_OPENGL=ON -D WITH_V4L=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_TBB=ON ..

Can I know what the way to solve this error. I have tried reinstalling my Python but still the same. I am using python2.7.10

Answer 1

After installing Eigen3 (via previous reply with apt or suggestion below), make sure that cmake is looking at eigen3 and not eigen2.

I used macports to get eigen3, so it looks like:

sudo port install eigen3

And the Cmake option:

EIGEN_INCLUDE_PATH=/opt/local/include/eigen3

Answer 2

Try installing package

sudo apt-get install libeigen3-dev

Worked for me in similar situation

Answer 3

在您的cmake脚本中添加“ -D WITH_EIGEN = OFF”。
