yocto recipe for this example

I have a very basic idea about Yocto. I have added python3-pybind11 package into IMAGE_INSTALL and I checked if it is in the target:

root@qemuarm64:~# python3
Python 3.8.18 (default, Aug 24 2023, 19:48:18) 
[GCC 9.5.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pybind11
>>> pybind11.__version__
'2.4.3'

The version is a bit old. Anyway I have changed pyproject.toml by lowering the version in the example:

[build-system]
requires = [
    "setuptools>=42",
    "pybind11>=2.4.0", # << changed this
]
...

With this change, I still can build and run the example locally.

I created this recipe by devtool add:

SUMMARY = "A test project using pybind11"
HOMEPAGE = "https://github.com/pybind/python_example"
LICENSE = "Unknown"
LIC_FILES_CHKSUM = "file://LICENSE;md5=153b3e05cd731791777324af9f7219b3"

SRC_URI = "git://git@gitlab.com/sharedlib/python-example-pybind.git;protocol=ssh;branch=master"

PV = "1.0+git${SRCPV}"
SRCREV = "e2350ed9dad1c5b424f840c21079d51976463e41"

S = "${WORKDIR}/git"

inherit setuptools3

RDEPENDS_${PN} += "python3-pybind11"

FILES_${PN} += "/usr/lib/"

And I got this error:

ERROR: python-example-1.0+git999-r0 do_compile: 'python3 setup.py build ' execution failed.
ERROR: python-example-1.0+git999-r0 do_compile: Execution of '/workspaces/devcontainer-do/build/tmp/work/aarch64-poky-linux/python-example/1.0+git999-r0/temp/run.do_compile.701172' failed with exit code 1

Can you help me?

Start with setup.py and pyproject.toml, then inspect the submitted Yocto recipe and the do_compile log showing the missing pybind11 module. Check how this example's build requirements are made available during the Yocto build. Done means the recipe builds successfully and produces a runnable example image.
