Hi,

I'm trying to build franka_gripper on ArchLinux, and got undefined reference error:

[100%] Linking CXX executable devel/lib/franka_gripper/franka_gripper_node

Any suggestions?

if you are using ubuntu and compile from terminal just add a flag "-pthread". I just met the similar problem in another project. just a tip lol.
