Hello,
I'm currently working with the following setup:
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!
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
