catkin_make error in cv_bridge building

[arjunskumar]

@MehmetcanKaymaz Can you try

sudo apt-get update
sudo apt-get install libpython-dev

[MehmetcanKaymaz]

@arjunskumar I tried but still have the same and I wonder why it uses python 2.7. should I use python 3?

[MehmetcanKaymaz]

@arjunskumar this is my CMakeList.txt file maybe the problem is in here,

cmake_minimum_required(VERSION 3.0.2)
project(cv_bridge)

find_package(catkin REQUIRED COMPONENTS rosconsole sensor_msgs)

if(NOT ANDROID)
find_package(PythonLibs)

if(PYTHONLIBS_VERSION_STRING VERSION_LESS "3.8")
# Debian Buster
find_package(Boost REQUIRED python3)
else()
# Ubuntu Focal
find_package(Boost REQUIRED python)
endif()
else()
find_package(Boost REQUIRED)
endif()

set(_opencv_version 4)
find_package(OpenCV 4 QUIET)
if(NOT OpenCV_FOUND)
message(STATUS "Did not find OpenCV 4, trying OpenCV 3")
set(_opencv_version 3)
endif()

find_package(OpenCV 3 REQUIRED PATHS /usr/local/share/OpenCV NO_DEFAULT_PATH

catkin_package(

catkin_python_setup()

if(NOT ANDROID)
add_subdirectory(python)
endif()
add_subdirectory(src)
if(CATKIN_ENABLE_TESTING)
add_subdirectory(test)
endif()

install the include folder

install(
DIRECTORY include/${PROJECT_NAME}/
DESTINATION ${CATKIN_PACKAGE_INCLUDE_DESTINATION}
)

@MehmetcanKaymaz Please check your python version

if(PYTHONLIBS_VERSION_STRING VERSION_LESS "3.8")
# Debian Buster
find_package(Boost REQUIRED python3)

if your version is less than 3.8,it will take python2
so the workaround is to change else condition to

find_package(Boost REQUIRED python3)

[MehmetcanKaymaz]

@arjunskumar The problem is not about finding boost I think

python version is 2.7.17
python3 version is 3.6.9
boost version is 1.65.1

[MehmetcanKaymaz]

I solved the problem using ros-perception/vision_opencv#329 (comment)

[arjunskumar]

Thanks @MehmetcanKaymaz
