When I run: ./waf configure --boost-libs /path/to/boost-libraries I get the following error, please help!

Thank you for your feedback. Honestly, we are not using this code right now and it probably need some refreshing / testing on modern systems, and I do not have the time for this right now.

Except if you need something very special, you should probably use the official dynamixel library by Robotis (it did not exist when we started this project). https://github.com/ROBOTIS-GIT/DynamixelSDK (I would say that our library is better, but they have more ressources for the maintenance...).

Thank you for your comment. I would probably use DynamixelSDK or dynamixel_interface for my project.

If I may add, the issue you are describing is most probably coming from an old version of the waf executable. In case you really want to use our library, you can try downloading a newer version of waf (here) and retry.

Hi @costashatz, I downloaded new waf, and error is same...

[costashatz]

Thanks for the update. I will try to use the library in the coming weeks and possibly attempt to fix the problem.. For the time being, I would suggest to follow @jbmouret 's advice and use the official repo for now..
