Hi I basically have the same problem

I am using a UI 1221LE camera from a raspberry pi running minibian with ROS indigo. The camera is confirmed to be working from a ubuntu environment but have problems starting it from the minibian.

I have installed the arm 7 drivers and started successfully the daemon. I have tried to use the ueye_cam from apt-get, everything was ok but could not launch. Now i have cloned the git, compiled with catkin successfully, but when trying to run roslaunch ueye_cam rgb8.launch

i get the output

/root/ueye/ueye_cam/catkin_ws/devel/lib/ueye_cam/check_ueye_api: error while loading shared libraries: libueye_api.so: cannot open shared object file: No such file or directory=REQUIRED process [check_ueye_api-1] has died! process has died [pid 7478, exit code 127, cmd /root/ueye/ueye_cam/catkin_ws/devel/lib/ueye_cam/check_ueye_api __name:=check_ueye_api __log:=/root/.ros/log/2823c8ee-1392-11e7-a344-b827eba280a7/check_ueye_api-1.log]. log file: /root/.ros/log/2823c8ee-1392-11e7-a344-b827eba280a7/check_ueye_api-1*.log Initiating shutdown!

I confirm to have sourced catkin_ws/devel/setup.bash also, i confirm that the directory /devel/lib includes the files libueye_cam_nodelet.so and libueye_wrapper.so and they are not empty.

Moreover, Having commented the line

node name="check_ueye_api" pkg="ueye_cam" type="check_ueye_api" required="true" /

** having followed this thread on the ros page, I get the same problem, but unable to fix.

Moreover. i tried also to compile the fuerte branch, but with no success.

Thank you!
