Good question.
Pybind11 might be finding its own python version instead of using the already found version.
Try running with the most recent commit, 89e26e0e6acc0f4d8e8a54710232fd2ed80da7b4, on master. As we both swtich the way python is found and we have updated to a newer pybind11 version.
@MatthijsBurgh I have already used the latest version: "commit 89e26e0e6acc0f4d8e8a54710232fd2ed80da7b4 (HEAD -> master, origin/master, origin/HEAD) Author: dependabot[bot] 49699333+dependabot[bot]@users.noreply.github.com Date: Wed Dec 21 23:06:00 2022 +0100"
When I did the cmake, I have already given the conda python 3.7 directory to DPYTHON_EXECUTABLE, but the cmake used the system python 3.8 to compile.
Stuck here for one day, please help. Thanks.
@MatthijsBurgh And, I did the install again, use the latest commit. another error came out "ImportError: liborocos-kdl.so.1.5: cannot open shared object file: No such file or directory"
I am using miniconda3+ python3.7 to use KDL.
Thanks.
The log you provided in your first message is definitely from before #425. As that was finding the Python Interpreter. Now the logs should look like this, where it find the python executable.

This sounds very much like a configuration issue. I don't work with conda environments. And especially not in combination with a catkin ws. Just make sure all your environments/ws are sourced correctly and in the correct order. (Don't ask me what the correct order is.) So the resulting environment variables and paths are correct.

Hi, I installed the PyKDL, but when I import PyKDL, the error came out
ImportError: Python version mismatch: module was compiled for Python 3.8, but the interpreter version is incompatible: 3.7.15 (default, Nov 24 2022, 21:12:53) [GCC 11.2.0].
.I am using UBUNTU 20.04. When i installed, I used:
cmake ../ -DPYTHON_EXECUTABLE:FILEPATH=/home/walter/miniconda3/envs/Robot_ur5e_ws/bin/python
And it showed:
I am not sure what is wrong, please help.
Thanks!
