Hi, I am trying to use these drivers on a Ladybug 5 camera. I am following the instructions and installed the current version of the ladybug sdk (ver 1.16.3.48). When I try to run catkin_make, I see the following error:

[100%] Linking CXX executable /home/USERXXX/apps/ladybug_ws/devel/lib/pointgrey_ladybug/ladybug_camera
/usr/bin/ld: cannot find -lflycapture

make: *** [all] Error 2

I have tried this on 2 different machines and it consistent. Have you seen this error before or have any ideas on how to address it?

Thanks, Vik

It looks like the current version of the ladybug sdk library installs in /usr/lib/ladybug instead of /usr/lib. I as able to fix the issue by adding the following line to CMakeLists.txt before the add_executable(ladybug_camera line:

link_directories(/usr/lib/ladybug)
