cannot install vision_opencv from binaries with libopencv-contrib-dev installed.

[JHeuverRiwo]

I need to have the aruco functionality provided in libopencv-contrib-dev. However the binary for image_geometry depends on libopencv-dev. These two packages conflict on my system and installing the one will uninstall the other.

Compiling image_geometry from source will result in the following error when I have libopencv-contrib-dev installed:

Starting >>> image_geometry                               
--- stderr: image_geometry                                      
CMake Error at CMakeLists.txt:18 (find_package):
  Could not find a package configuration file provided by "OpenCV" (requested
  version 4) with any of the following names:

    OpenCVConfig.cmake
    opencv-config.cmake

  Add the installation prefix of "OpenCV" to CMAKE_PREFIX_PATH or set
  "OpenCV_DIR" to a directory containing one of the above files.  If "OpenCV"
  provides a separate development package or SDK, be sure it has been
  installed.

jetson orin nx 16gb (zedbox)

jetpack: 5.1.1

Apologise it took a while to get back.

In your case, since you're looking for Aruco functionality, you will need libopencv-contrib-dev, but you'll need to install both libopencv-dev (for the core functionality) and libopencv-contrib-dev (for the extra functionality), not just libopencv-contrib-dev.

I am not sure why you are having issues installing the two libraries side-by-side. In fact, libopencv-dev installs libopencv-contrib-dev as a dependency so installing libopencv-dev is sufficient.

I noticed you have an odd ubuntu / ros distro combo (most likely due to some complications with upgrading the OS on the jetson). Something there may be preventing you from installing to the two libraries side-by-side
