Invalid Pointer when running roslaunch phoxi_camera.launch

[neerja123-gupta]

Hello,

I am using Ubuntu 20.04 and ros noetic. I installed this package and downloaded the latest PhoXi ControlPhoxi Control APP for ubuntu 20. I am able to build this package using catkin build. However, when I am running "roslaunch phoxi_camera phoxi_camera.launch" its giving an error free(): invalid pointer process has died. Any help would be highly appreciated. Thanks.

I had the same issue, and while debugging, found that linking against the Debug build of PhoxiControl gets around this problem.

ie. Linking against. ${PHOXI_LIB_DEBUG} instead of ${PHOXI_LIBRARY}
