catkin build failed

[XieWup]

Hi,
after running the "catkin build" command, the terminal printed the following error:

WARNING: Your current environment's CMAKE_PREFIX_PATH is different from
the cached CMAKE_PREFIX_PATH used the last time this workspace was
built.

If you want to use a different CMAKE_PREFIX_PATH you should call catkin clean to remove all references to the previous CMAKE_PREFIX_PATH.

Cached CMAKE_PREFIX_PATH:
/home/liangs/anjoy_ws/devel:/opt/ros/melodic
Current CMAKE_PREFIX_PATH:
/home/liangs/anjoy_ws/devel/.private/catkin_tools_prebuild:/home/liangs/anjoy_ws/devel:/opt/ros/melodic

seems the wrong version of opencv?

OK . What version of OpenCV are you using

OK . What version of OpenCV are you using

ros-noetic-vision-opencv 1.16.2-1focal.20230620.193649 and libopencv-dev 4.2.0+dfsg-5

if you needed, I can share my docker container.

Oh, Your environment is quite different from mine, maybe I should try another solution. Thank you very much

if you try it in melodic, I guess you need to change a lot of things XD.

Hi @XieWup,

GroundGrid targets ROS Noetic Ninjemys, so compiling it with an older ROS distribution (it looks like you're using melodic) might lead to compiler/runtime issues.
This particular error with the OpenCV colormap can be easily fixed by using another colormap or removing the colormap function call. It is only needed for visualization purposes and it is not used for the ground segmentation. However, you might face more errors that might be more difficult to fix. That's why I'd recommend upgrading the ROS installation.
