Getting an error with getConversionCode and SAME_FORMAT

[JohnVorwald]

Hello,
I'm getting errors trying to build the package

https://github.com/maciejmatuszak/ros_gpu_stereo_processor/tree/master/src

Here are the error message

error: ‘getConversionCode’ is not a member of ‘cv_bridge’
const std::vector conversion_codes = cv_bridge::getConversionCode(src_encoding, dst_encoding);

error: ‘SAME_FORMAT’ is not a member of ‘cv_bridge’
if (conversion_code == cv_bridge::SAME_FORMAT)

I tried uninstalling and reinstalling cv_bridge, but same result

sudo apt-get remove --auto-remove ros-melodic-cv-bridge
sudo apt-get install ros-melodic-cv-bridge
sudo apt-get install ros-melodic-stereo-msgs
sudo apt-get install ros-melodic-ddynamic-reconfigure
catkin_make --pkg gpuimageproc

Here is where cv_bridge is located

catkin_find cv_bridge
/opt/ros/melodic/include/cv_bridge
/opt/ros/melodic/share/cv_bridge

Here is debug output from CMakeList.txt

The repository you pointed to seems to be relying on a modified version of vision_opencv (without telling you), and you're trying to use the non-modified official version of vision_opencv, and the differences are causing the error.

As there is nothing to fix in this repository, I'm going to close this off. Please get in touch with maciejmatuszak to figure out where his modified branch is, perhaps you can find his fork in his github account.
