Hello, I want to use ros_canopen package to communicate via can. The communication should be done via a USB to can converter from the company Ixxat. Which steps are necessary to use the converter?

Thanks for your answer.

Looks like Ixxat supports SocketCAN for some devices. If you can use that, everything should work as usual.

If not, you could provide your own driver plugin for canopen_motor_node (for motor drives).
Unfortunately, there is still no support for these plugins in the bridge nodes (Issue).

Thanks for your answer. The SocketCan driver works. But if I want to compile the canopen package via catkin, then I get an error. /usr/include/c++/5/bits/hashtable_policy.h: error: no match for call to '(const std::hash<canopen::motorbase::operationmode>) ... Followed by many other errors..

Are you sure you are compiling the kinetic-devel branch? Not the melodic-devel one?

where can i see this? and where can I get the right version?

If you've cloned the repository using git clone, then a git status or git branch should show you which particular branch is currently checked out.

If you've downloaded a zip from github, the branch name should be part of the filename.

Also: please make sure you actually have to build the packages yourself. Otherwise just use apt to install them.

Thanks for your answer. I downloaded it now as a correct zip file and then it works. When I clone it, it always downloads the melodic version. Thanks!

When I clone it, it always downloads the melodic version.

No, it downloads all versions, but melodic-devel is the default branch, so that one is 'active'.

You'll need to checkout the correct branch.

But again: make sure you actually need to build things from source.
