Could not find SIP during build?

[eugval]

Hello,

I am trying to follow the steps described in this issue in order to get a PyKDL binding with python3 as the one I installed through ros only imports correctly with python2 .

I cloned the master branch in this repository and followed step by step the procedure described in the thread:

When building python_orocos_kdl, I get the following error:

I have installed SIP with pip3 : pip3 install --user SIP .
When I also type : pip install --user SIP, but I the following :

my PYTHONPATH is the following:

I also seem to have sip in my system:

Also:

I am quite confused about this, I suspect I am having a path issue but I cannot figure it out!

I would greatly appreciate any help understanding what is happening here, and how can I fix this as I am stuck trying to build the package!

My issue seemed to be that SIP was compiled and installed for python2, not python3.

This has nothing to do with the pip package that is just a binding (Please correct me if I'm wrong).

To install SIP for python3, I followed the instructions in here.

After this, the build worked!
