catkin_make_isolated error

mpena2099 commented 3 years ago

Hi!

catkin_make_isolated not working on my Ubunu 20.04, ROS noetic.

Steps:

git clone https://github.com/GT-RAIL/async_web_server_cpp.git

sudo apt-get install libjsoncpp-dev
sudo ln -s /usr/include/jsoncpp/json/ /usr/include/json

git clone https://github.com/RobotWebTools/webrtc_ros

Now, catkin_make_isolated:

(...)
[ 53%] Built target webrtc_ros_server_noncpp11
[ 57%] Linking CXX shared library /home/mauricio/catkin_ws/devel_isolated/webrtc_ros/lib/libwebrtc_ros_server.so

<== Failed to process package 'webrtc_ros': 
  Command '['/home/mauricio/catkin_ws/devel_isolated/webrtc/env.sh', 'make', '-j4', '-l4']' returned non-zero exit status 2.

Reproduce this error by running:
==> cd /home/mauricio/catkin_ws/build_isolated/webrtc_ros && /home/mauricio/catkin_ws/devel_isolated/webrtc/env.sh make -j4 -l4

Command failed, exiting.

Any ideia?

Thanks! Mauricio

I tried to use the Docker and it seems to be OK.

As a Ubuntu 20.04 user with ROS Noetic, I have encountered the issue of /usr/bin/ld: cannot find -ljsoncpp_object too. One thing that can be done for a successful build is to change the following in webrtc_ros/CMakeLists.txt:

target_link_libraries(${PROJECT_NAME}_server
  ...
  jsoncpp_object
  ...
)

to:

target_link_libraries(${PROJECT_NAME}_server
  ...
  jsoncpp_lib
  ...
)

This ensures that the correct object is linked to.
