MagicalTux opened a new issue, #40566:
URL: https://github.com/apache/arrow/issues/40566
### Describe the bug, including details regarding any error messages,
version, and platform.
Specifically, I am trying to build pyarrow but hit the following error:
```
-- Found Python3: /pkg/main/dev-lang.python.core.3.12.2/bin/python3 (found
version "3.12.2") found components: Interpreter Development.Module NumPy
CMake Error at cmake_modules/FindPython3Alt.cmake:77 (message):
Python 3 config failure:
Traceback (most recent call last):
File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'distutils'
Call Stack (most recent call first):
CMakeLists.txt:262 (find_package)
-- Configuring incomplete, errors occurred!
```
This is due to the code at
https://github.com/apache/arrow/blob/main/cpp/cmake_modules/FindPython3Alt.cmake#L70
which uses `distutils` to obtain EXT_SUFFIX which is not valid on python 3.12.
I would suggest using this code instead:
```
"import importlib.util; sysconfig =
importlib.import_module('distutils.sysconfig') if
importlib.util.find_spec('distutils') else
importlib.import_module('sysconfig');
print(sysconfig.get_config_var('EXT_SUFFIX'))"
```
This will automatically import the right package depending on the
availability of distutils and return the right value.
