ubuntu22.04 vs ubuntu20.04 libjsoncpp-dev installation

[ckinsung85]

I git clone the OpenCalib git to two OS ubuntu20.04 and ubuntu22.04

I noticed under ubuntu22.04, I was stucked in the installation of

sudo apt-get install libjsoncpp-dev

... [ 50%] Building CXX object CMakeFiles/CameraCalibration.dir/src/run_intrinsic_calibration.cpp.o [ 66%] Linking CXX static library ../lib/libCameraCalibration.a [ 66%] Built target CameraCalibration [ 83%] Building CXX object CMakeFiles/run_intrinsic_calibration.dir/src/run_intrinsic_calibration.cpp.o [100%] Linking CXX executable ../bin/run_intrinsic_calibration /usr/bin/ld: cannot find -ljsoncpp: No such file or directory collect2: error: ld returned 1 exit status make[2]: [CMakeFiles/run_intrinsic_calibration.dir/build.make:150: ../bin/run_intrinsic_calibration] Error 1 make[1]: [CMakeFiles/Makefile2:111: CMakeFiles/run_intrinsic_calibration.dir/all] Error 2 make: *** [Makefile:91: all] Error 2

Running of mkdir -p build && cd build cmake .. && make

was not successfull!!!

However, getting stucked for several times, I chose to reinstall my OS from ubuntu22.04 to ubuntu20.04 and the problem was solved.

Now, I am able to run

cd ./intrinsic_calib/ ./bin/run_intrinsic_calibration ./data/

Write down the relevant packages installed for the succesful running of the codes

1. Installation of Ubuntu20.04

2. sudo apt install git

3. git clone https://github.com/PJLab-ADG/SensorsCalibration.git

4. sudo apt install cmake

5. sudo apt-get install build-essential
   sudo apt-get install g++

6. sudo apt install libgtk2.0-dev pkg-config

7. sudo apt install libcanberra-gtk-module libcanberra-gtk3-module -y

8. Install OpenCV

   # Install minimal prerequisites (Ubuntu 18.04 as reference)
   sudo apt update && sudo apt install -y cmake g++ wget unzip
   
   # Download and unpack sources
   wget -O opencv.zip https://github.com/opencv/opencv/archive/4.x.zip
   wget -O opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/4.x.zip
   unzip opencv.zip
   unzip opencv_contrib.zip
   
   # Create build directory and switch into it
   mkdir -p build && cd build
   
   # Configure
   cmake -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib-4.x/modules ../opencv-4.x
   
   # Build
   cmake --build .
   
   # 
   sudo make install

9. sudo apt install libpcl-dev

10. cd ./intrinsic_calib/
    ./bin/run_intrinsic_calibration ./data/

If you replace libjsoncpp.a with ${JSONCPP_LIBRARIES} in the CMakeLists.txt file and install cppjson via

sudo apt-get install libjsoncpp-dev

it should compile without errors.
