Do `` make -j `nproc` update_bindings `` but get ImportError: cannot import name 'Protocol'**

[Radiance-nt]

Finnaly, the libs (including _util.so, _based.so) have been generated. I made it in v1.5.2.

I faced some problem when compiling latest OMPL (v1.6.0), and switched to v1.5.2.
I created a virtual env in build/venv, and a folder build/local as the installation directory, build/Release as the build directory.
After activating the venv, run pip install numpy wheel pyplusplus pygccxml==2.2.1 to install the required libs.
Before cmaking, the required pkgs that should be installed with apt must be required as well.

After preparation, run cmake with the following commands,

CXXFLAGS="-std=c++17  -fsized-deallocation" cmake -DCMAKE_CXX_COMPILER=/usr/bin/g++-9 -DPYTHON_EXEC=`which python` -DOMPL_BUILD_PYBINDINGS=ON -DCMAKE_INSTALL_PREFIX=$(dirname $PWD)/local ../../

I think this would help to isolate enviroments and avoid underlying issues. By the way, I tried g++-10 but it did not work for my case.
Another issue is the bindings of OMPL (v1.5.2) have problems compiling with c++17 standard (which is needed for Spot), so I make that target use c++14 standard ,
I add this standard to something like add_custom_target(update_bindings) in a cmake file.

After that, I ran make update_bindings and make, the _*.so files successfully came out in build/Release/lib.

Overall [v2.2.1] of PyGCCXML seems to be the key solving problems along with python3.8. Thank everyone who gave helpful suggestions. Although my installation procedures are so complex, at least the py-bindings can work.

[Radiance-nt]

I also got the same error when making update_bindings.
I tried OMPL 1.4,2 1.5.2, 1.6.0, but all attempts had failed.

When I tried to from typing import Protocol interactively, it seems normal:

(base) radiance@radiance:~$ /usr/bin/python3
Python 3.8.10 (default, May 26 2023, 14:05:08) 
[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from typing import Protocol
>>> Protocol
<class 'typing.Protocol'，

I also tried to repalce typing with typing_extensions, but more errors came out.
I speculate the errors have something to do with pyplusplus, but not be sure.

Logs are given:

Ubuntu20.04安装OMPL安装指南

[zkingston]

Two things:

• It appears that you downloaded the source zip for OMPL.app, could you clone the latest version of OMPL?
• Since you are using Python 3.8, can you use v2.2.1 of PyGCCXML?

Then clean and re-build
