colcon build --mixin release: moveit_task_constructor_core error

[2vin2vin]

Description

Overview of your issue here.

Your environment

• ROS Distro: Humble
• OS Version: Ubuntu 22.04
• python version: 3.10
• https://moveit.picknik.ai/main/doc/tutorials/getting_started/getting_started.html
  Followed the above tutorial with humble as the branch

During colcon build got the below error
Starting >>> moveit
--- stderr: moveit_task_constructor_core
CMake Error at python/pybind11/tools/FindPythonLibsNew.cmake:163 (message):
Python config failure:

Traceback (most recent call last):

Failed <<< moveit_task_constructor_core [1.30s, exited with code 1]

I seem to have sysconfig and it seems to work as well

I checked for the file FindPythonLibsNew.cmake and got the following
/home/2vin/.local/lib/python2.7/site-packages/pybind11/share/cmake/pybind11/FindPythonLibsNew.cmake
/home/2vin/.local/lib/python3.8/site-packages/pybind11/share/cmake/pybind11/FindPythonLibsNew.cmake

but I also seem to have the file in
/home/2vin/.local/lib/python3.10/site-packages/pybind11/share/cmake/pybind11/FindPythonLibsNew.cmake
but not detected in locate

so I have been trying everything I can since 2 days but unable to resolve it.

Looks like you screwed your python environment. I guess, you have multiple python binaries and the wrong one is used.
The cmake file should come from moveit_task_constructor/core/python/pybind11/tools/FindPythonLibsNew.cmake.
Maybe you can use colcon build --cmake-args --trace to get verbose cmake output and figure out which python binary is used.
As a last resort, I suggest cleaning up ~/.local/lib/python*. However, this might break other apps!

Failed <<< moveit_task_constructor_core [22.5s, exited with code 1]
I have also tried to check the python version from python terminal it seems to be 3.10 and also as you said it is being taken from moveit_task_constructor
I have actually upgraded fromubuntu 20 to 22 and then tries to install this and I have been facing issues continuously I have tried to resolve most of them but I am unable to solve this

Also distutils.setuptools exists but it seems to be generating deprecated warning

You still didn't figure out which python executable is called by cmake. Try to print the cmake variable PYTHON_EXECUTABLE in /home/2vin/ws_moveit/src/moveit_task_constructor/core/python/pybind11/tools/FindPythonLibsNew.cmake:129
