Issue in compilation of the packages #2
Description
On trying to run catkin build command, i am getting the following error:
Errors << dobot_v4_bringup:make /home/********/dobot_ws/logs/dobot_v4_bringup/build.make.000.log In file included from /home/********/dobot_ws/src/TCP-IP-ROS-6AXis/dobot_v4_bringup/src/cr5_v4_robot.cpp:16: /home/********/dobot_ws/src/TCP-IP-ROS-6AXis/dobot_v4_bringup/include/dobot_v4_bringup/cr5_v4_robot.h:17:10: fatal error: nlohmann/json.hpp: No such file or directory 17 | #include <nlohmann/json.hpp> | ^~~~~~~~~~~~~~~~~~~ compilation terminated. make[2]: *** [CMakeFiles/dobot_v4_bringup.dir/build.make:63: CMakeFiles/dobot_v4_bringup.dir/src/cr5_v4_robot.cpp.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:1743: CMakeFiles/dobot_v4_bringup.dir/all] Error 2 make: *** [Makefile:141: all] Error 2 cd /home/********/dobot_ws/build/dobot_v4_bringup; catkin build --get-env dobot_v4_bringup | catkin env -si /usr/bin/make --jobserver-auth=3,4; cd -
Since i had to do some testing on the Rviz simulation, i removed the package temporarily removed the package that wasn't compiling, but still got the following error:
Errors << rosdemo_v3:cmake /home/********/dobot_ws/logs/rosdemo_v3/build.cmake.000.log CMake Error at /home/********/dobot_ws/src/TCP-IP-ROS-6AXis/rosdemo_v3/CMakeLists.txt:52 (add_executable): Target "rosdemo_v3" links to target "nlohmann_json::nlohmann_json" but the target was not found. Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing?
I modified dependencies in other packages relating to these, and was able to complete the build. But without the bring up files, I can not do the testing with the actual hardware.
I tried looking into the ROS dependencies and it seems like all the required rosdep for ROS noetic is installed. Please let me know if there is a fix for this issue.
