Hello, In the ROS community, a lot of developers use the 'python-orocos-kdl' library, https://github.com/orocos/orocos_kinematics_dynamics, which generates its python bindings with SIP. The versions of SIP between 4.16.7 and 4.19.20 contain bugs which make the 'python-orocos-kdl' hard to use.
I worked with the developer of SIP to fix these bugs. These are fixed in the new release 4.19.21, as can be seen on https://www.riverbankcomputing.com/hg/sip. I would like to ask you to update the python-sip package on all ubuntu release 16.04 and newer to 4.19.21. This would make it possible to generate a new version of 'python-orocos-kdl', which would help a lot of developers. Met vriendelijke groeten/Kind regards, Matthijs van der Burgh
