# Documentation Right now our [How-To Clinic guide](https://docs.python.org/3.12/howto/clinic.html) does not mention that it is required to run `python Tools/scripts/generate_global_objects.py` command to generate global objects used by `_Py_ID()`, like in here: ```C #define NUM_KEYWORDS 1 static struct { PyGC_Head _this_is_not_used; PyObject_VAR_HEAD PyObject *ob_item[NUM_KEYWORDS]; } _kwtuple = { .ob_base = PyVarObject_HEAD_INIT(&PyTuple_Type, NUM_KEYWORDS) .ob_item = { &_Py_ID(only_keys), }, // <--- Here! }; #undef NUM_KEYWORDS ``` With this command the build fails. I will send a PR to update docs today. CC @larryhastings :)
