Up to Python 3.10 our Boost Python binding ran fine. As of Python 3.11 we get the following error upon import of the binding;
SystemError: type Boost.Python.enum has the Py_TPFLAGS_HAVE_GC flag but has no traverse function
Running; Python 3.11.0 (main, Oct 24 2022, 18:26:48) [MSC v.1933 64 bit (AMD64)] on win32 boost_1_80_0 b2 -j%NUMBER_OF_PROCESSORS% python=3.11 --with-python --stage-libdir=lib64-msvc-14.3 --build-type=complete toolset=msvc-14.3 address-model=64 architecture=x86 debug-symbols=on stage
If I remove line 116 of libs\python\src\object\enum.cpp I don't get the error.
#if PY_VERSION_HEX < 0x03000000 | Py_TPFLAGS_CHECKTYPES #endif | Py_TPFLAGS_HAVE_GC /* <============== remove this line */ | Py_TPFLAGS_BASETYPE, /* tp_flags */
Is it safe to do this?
Fixed;
