Hey guys, It's me again. Sorry for the high traffic. I released the openni_tracker and the source build works fine. However, when building the deb, orocos-kdl can't be found. CMake Error at /opt/ros/hydro/share/catkin/cmake/catkinConfig.cmake:72 (find_package): Could not find a configuration file for package orocos_kdl. Set orocos_kdl_DIR to the directory containing a CMake configuration file for orocos_kdl. The file will have one of the following names: orocos_kdlConfig.cmake orocos_kdl-config.cmake Call Stack (most recent call first): CMakeLists.txt:3 (find_package) So, I started looking for the cause of this and found this seemingly related issue involving the geometry stack: https://github.com/ros/geometry/issues/11. The respective fix treats orocos-kdl as a plain Cmake package instead of a catkin package. Unfortunately, when applying this patch to the openni_tracker, my local source build can't find the orocos-kdl library it tries to link to: Linking CXX executable /opt/sandbox_workspace/devel/lib/openni_tracker/openni_tracker /usr/bin/ld: cannot find -lorocos-kdl collect2: ld returned 1 exit status make[2]: *** [/opt/sandbox_workspace/devel/lib/openni_tracker/openni_tracker] Error 1 Again I started off to find hints for the cause of this. I took a look at orocos_kdl-config.cmake and even the package config file, but nothing seems suspicious to me. However, I must say that I don't have lots of CMake experience. So this is harder for me than Korean. 0o One thing I noticed though is that the CMake log output about orocos-kdl doesn't show any linker flags: Looking for KDL in: /opt/ros/hydro -- checking for one of the modules 'orocos_kdl' Includes in: /opt/ros/hydro/include;/usr/include/eigen3 Compiler flags: -I/opt/ros/hydro/include;-I/usr/include/eigen3 Libraries: orocos-kdl Libraries in: /opt/ros/hydro/lib Linker flags : Defines: I will keep looking further into this. But any hints, tips and help is highly appreciated! Thanks for reading, Marcus -- Marcus Liebhardt Control Engineer Yujin Robot ÁÖ¼Ò: ´ëÇѹα¹ ¼­¿ï½Ã ±Ýõ±¸ °¡»êµ¿ 345-30 ³²¼ºÇÁ¶óÀÚ #601, 153-023.
