[BUG]: Ubuntu, CMake, .so file is built but no python library. about nanobind HOT 6 CLOSED

".so"(on linux) and ".pyd"(on windows) files are basically the same. Have you tried import NanoTest?

from nanobind.

@a603032070 Yes I tried, no module found.
I changed binding name to my_ext to be inline with the example. I checked on my system I have python 3.11.

I also tried to give a path directly to the .so file:

import sys
sys.path.append('/home/petras/brg/2_code/ShapeOp/build/')
import my_ext

Still the same error.

I removed any 3rd party libraries and just left nano, could you check my repository:

I've checked your repo. It works well. Maybe something wrong about the path(or permissions)?

The issue is in python version. In my base environment with python 3.11 it works.
But with my conda environment where python is 3.9 it does not.

How you can specify in CMakelists which python version the library is built for?

from nanobind.

I don't really know. Maybe it's about this line in Cmakelists.
find_package(Python 3.9 COMPONENTS Interpreter Development.Module REQUIRED)

ExternalProject_Add is not a supported way of dealing with the nanobind dependency, I don't use it and cannot provide support for it.

I also suspect you are working partly on windows and on Linux (WSL?), hence the confusion about .pyd and .so files which are for different operating systems.

Anyways, these are all not bugs bug issues with your setup. Please don't open tickets here unless you are certain to have found a bug in nanobind.
