Installation from source fails because of cv_bridge include dir

Question

I'm trying to install ROS from source on Fedora 20 as per http://wiki.ros.org/indigo/Installation/Source. It fails with:

    CMake Error at /home/jfstepha/ros_catkin_ws/install_isolated/share/cv_bridge/cmake/cv_bridgeConfig.cmake:106 (message):
  Project 'cv_bridge' specifies '//include/opencv' as an include dir, which
  is not found.  It does neither exist as an absolute directory nor in
  '/home/jfstepha/ros_catkin_ws/install_isolated///include/opencv'

The correct path should be "/usr/include/opencv", somehow it seems to be missing the "usr". Also, it successfully builds 153 packages before this, so it doesn't seem to be a general setup issue.

I'm having a hard time figuring out where this path comes from - can anyone help?

Perhaps this is related: http://answers.ros.org/question/198058/cmake-error-while-building-rpg_svo/ ?

@ahendrix: It could possibly be somehow related in that it could be an opencv configuration bug, but the root cause of that one had to do with the Nvidia TK1 Jetson board, which I am not using. It could be the same environmental variable is missing or something.

Answer 1

The problem was that OpenCV_INCLUDE_DIRS was not getting set properly. It gets set by this line in /usr/lib64/OpenCVConfig.cmake

set(OpenCV_INCLUDE_DIRS "${OpenCV_INSTALL_PATH}/include/opencv;${OpenCV_INSTALL_PATH}/include")

The root cause is probably that OpenCV_INSTALL_PATH is not set properly, but I just changed the line to this:

set(OpenCV_INCLUDE_DIRS "/usr/include/opencv;/usr/include")

This seemed to work.

Answer 2

In my case in Jetson Nano, the error happened when I ran catkin_make clean for the first time.

The actual path for OpenCV include files was /usr/include/opencv4/opencv2 though /usr/include/opencv was expected.

So, after this actual path is written correctly in the cv_bridgeConfig.cmake file, the error disappeared.

The same happened here. Thank you for the correction!

Answer 3

I'm on a Nvidia Jetson platform.

As said above, cv_bridge expects /usr/include/opencv but on jetson systems it's under /usr/include/opencv4/opencv2

The quickest way to solve this, without rewriting config files is to symlink the directories:

sudo ln -s /usr/include/opencv4/opencv2/ /usr/include/opencv

I think this is the best way to go, as it will fix issues with other scripts trying to find opencv in the future.

Thanks, this solved my problem when running on NVida Xavier!
