I see! Thanks for the explanation!

Hi there,

In my ros2 package, I want to compile the node with a shared library, which is an SDK shared library provided by the manufacturer of the hardware. I am able to compile my code with link_directories that points to the location of the shared library (which locates inside the ros2 package).

Back in ROS1, that's it. I could execute my node and it will load the shared library correctly during runtime.

However, in ROS2, I have to install all the files to DESTINATION lib/${PROJECT_NAME} like this:

install(FILES 
${ORBBEC_SDK_LIB_DIR}/libOrbbecSDK.so.1.5
${ORBBEC_SDK_LIB_DIR}/libOrbbecSDK.so.1.5.7
${ORBBEC_SDK_LIB_DIR}/libOrbbecSDK.so
${ORBBEC_SDK_LIB_DIR}/libudev.so
${ORBBEC_SDK_LIB_DIR}/libudev.so.1
${ORBBEC_SDK_LIB_DIR}/libudev.so.1.6.3
DESTINATION lib/${PROJECT_NAME}
)

Apparently, this just copied and pasted these files to DESTINATION lib/${PROJECT_NAME}.

Another option that could work is that I can make an environment hook to add the folder of the shared library to LD_LIBRARY_PATH.

Both solutions are kind of gross.

What is the proper way of doing this?

In ROS 1 how does it find the shared library in the src folder? Since the setup.bash does not modify the LD_LIBRARY_PATH, I have no idea how does it find the shared library object. (I am sure the .so file is not in the system library.)

Without the correct ENU convention, you need to disable the orientation of the IMU from fusing into the global EKF. This

Hi there,

I am using ROS noetic on a ubuntu 20.04.1.

I am new to ROS and I am so confused about the package installation. For example, if I want to install the robot localization package, Do I just git clone it using the following command into my workspace?

$git clone -b noetic-devel https://github.com/cra-ros-pkg/robot_localization.git

I notice that package can be install through apt, but how can I know that apt command for the package I want?
