Thanks, It solves my problem as well !

Hi Steven, Yes, the ip I pass it in the rosrun as well, but after your comment I checked and infact, my node name for the driver was the same as the package name and I thought the name that I insert in the launch file, doest not need to be exactly the same. Thanks for your answer

and here is the launch file for the node :

    <launch>
<node name="polar_process" pkg="pleora_polarcam" type="process_stokes_node" output="screen" />
    </launch>

here is the launch file for the driver : <launch>

<node name="pleora_polarcam_driver" pkg="pleora_polarcam" type="pleora_polarcam_driver" args="_ip:=169.254.56.68" output="screen"/>

    </launch>

I am just started to work with ROS and I am facing a strange problem. I have executable based on camera driver and another executable which just show the images grabbed (imshow_node). While I start the driver using rosrun and either rosrun or roslaunch imshow_node everything works fine, however if I use roslaunch to start the dirver, and then roslaunch the imshow_node it doesnt show the images, it doesnt give me error neither.

I dont know if anyone came cross this problem before and I appreciate your help Cheers.

The problem was solved by adding the following line in the beginning

add_definitions(-DBOOST_LOG_DYN_LINK=1)

and also changing ${Boost_INCLUDE_DIR} to ${Boost_INCLUDE_DIRS} (Note: "DIRS" not "DIR") as per the wiki page on CMakeLists.

I followed most of the answers on how to link properly a library and still I cant compile my package with catkin_make, due to undefined reference to boost::log::v2s_mt_posix::trivial::logger::get()

Here is my the summary of my CMakeList.txt:
