cap-grant-ld's Issues

Incomplete setup with ROS2 Foxy

Hi,

I'm looking for a cleaner solution than what we achieved with shadow-robot/ethercat_grant#10 on Ubuntu 20 with ROS2 Foxy & SOEM.

Initial compilation failed with the following error :

--- stderr: cap_grant_ld
CMake Error at CMakeLists.txt:36 (file):
  file does not recognize sub-command REAL_PATH

REAL_PATH require Cmake 3.19. It might be useful to edit the CMakeList accordingly. Also, for people using ROS, How can I update/remove cmake without partially deleting my ROS distribution? might be useful.

I also installed libcap-ng-dev & libprocps-dev with rosdep install --from-paths src --ignore-src -r -y from the workspace folder.

Compilation went fine but it seems that "/install/cap_grant_ld/share/cap_grant_ld/local_setup.bash" is missing, preventing the use of the package in a Launch file at the same time. Do you know how to solve this issue ?

Thank you for your work !
Cheers

Not working on Ubuntu 22.04 + ROS 2 Humble

Hello,

I'm currently working with the following setup:

• Ubuntu 22.04
• ROS 2 Humble
• SOEM

With root user the EtherCAT interface is working properly.
I've installed cap_grand_ld with colcon and used prefix = 'ros2 run cap_grant_ld cap_grant_ld' in the launch file. The launch works correctly as the node starts but when it tries to connect to EtherCAT I get an error saying that the interface is not available. It's the same interface as with root user.

Could I be missing something regarding the installation for ROS packages?

Thanks in advance!
