I am trying to build opencv with opencv_contributions, but I can`t figure out this error at building.
I made cmake like this :
cmake -DOPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-master/modules/ ~/opencv-3.2.0/
And at the end of building i got this error:

Attempting to build open OpenCV in Ubuntu, following this tutorial (specifically the "Build core modules" section), and I get the following error:

I imagine this is a missing dependency, but I'm having a hard time finding it. Anyone have a fix?

I am trying to build this code:https://github.com/yjxiong/dense_flow/tree/opencv-3.1
I am using Ubuntu 16.04 and have OpenCV 3.4 installed.
xfeatures2d.hpp can't be found on the system.
I have looked at many different problems on the internet, but couldn't find a solution.
the error as below:

Any help is awesome!
I tried to install opencv-3.4.0 according to the tutorials https://github.com/TadasBaltrusaitis/OpenFace/wiki/Unix-Installation,
but when I finished cmake，then try make -j8, it failed at 30%. Does anyone know the solution and can help me? Thank you very much.

I am trying to build an open source library (openCV in this case) from source using cmake and make. However, I run into a linking error
Linking CXX shared library ../../lib/libopencv_videoio.so
/usr/bin/ld: /usr/local/lib/libc.a(lib_a-mallocr.o): relocation R_X86_64_32S against `__malloc_av_' can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/libc.a: error adding symbols: Bad value
collect2: error: ld returned 1 exit status
make[2]: *** [lib/libopencv_videoio.so.3.0.0] Error 1
make[1]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2
make: *** [all] Error 2
From what I gather, this means make is using the static version of glibc libc.a instead of the dynamic lib.so.6. I'm assuming I need to change a path somewhere in cmake but I'm unsure of where to look. Any help is appreciated.
edit: I'm doing this on a 64 bit linux mint machine
