Hi, I always get this error:

/usr/bin/ld: CMakeFiles/mechanum_steering_node.dir/__/drive/interface/SocketCAN.cpp.o: undefined reference to symbol 'pthread_create@@GLIBC_2.2.5'

When I add Thread as REQUIRED_COMPONENTS and target_link_libraries it works again for this specific package. How can I solve this globally?

I'm using Arch Linux, packages are built with makepkg.

I simply had to recompile rostime, cpp-common and roscpp, now everything works again.

I'm trying to do catkin_make with python3 on Arch Linux, but I get this error:

Can anyone please help me solving this issue, seems some part of catkin wasn't generated before.

I solved it by specifiying the interpreter value with the full path. Before, I used catkin_make --cmake-args -DPYTHON_E

So I'll do a little bit research tomorrow trough cmake's python linking. Thanks for your suggestions.

Do you know which package is mandatory for the python executable?

None of both files exist.

The file pacakge.cmake doesn't exist. And since catkin_make never finished successfully, there neither a py3 nor py2 bin
