[BUG]: undefined symbol: Py_REFCNT (Python 3.14) #1183
Description
Problem description
The Py_REFCNT function is not part of the stable API in Python 3.13 and earlier, but it is used unconditionally in nb_ft.h:
Line 17 in 116e098
As a result, nanobind modules built using Python 3.14.0rc3 with Py_LIMITED_API=0x030c0000 cannot be imported on Python 3.12 and 3.13; they fail with libnanobind-abi3.so: undefined symbol: Py_REFCNT.
Reproducible example code
