error: ‘rc_imu_read_mutex’ undeclared

[MarkAYoder]

Looks like you have a great package here for working with the BeagleBone Blue.

I'm working with a Blue running "BeagleBoard.org Debian Image 2017-04-23" I'm having trouble getting rcpy installed. I've installed Robotics_Cape_Installer, ctrl and rcpy. In ctrl I ran sudo python3 setup.py install and it appears to have installed without error.

However when installing in rcpy in get an error $ cd rcpy $ sudo python3 setup.py install

I don't know where rc_imu_read_mutex and rc_imu_read_condition are defined.

Any suggestions?

For now you will need to compile the robotics cape library using my fork

https://github.com/mcdeoliveira/Robotics_Cape_Installer

since James have not incorporated the mutexes in his version yet.

That did it. Many thanks for the quick response.
