PyTuple_SET_ITEM fails to compile in C++ source #93442
Description
- CPython versions tested on: 3.11b3
- Operating system and architecture: Debian Linux, GCC 10.2.1-6
The kiwisolver extension doesn't compile with beta 3. The error is:
/usr/local/python3.11.0b3/include/python3.11/pyport.h:47:24: error: invalid ‘static_cast’ from type ‘int’ to type ‘_object*’ 47 | return static_cast<type>(const_cast<expr_type &>(expr)); | ^~~~~ This seems to be an issue with the new inline functions for things that used to be macros. E.g. PyTuple_SET_ITEM. The C++ code triggering the issue is:
--- a/py/src/symbolics.h +++ b/py/src/symbolics.h @@ -123,7 +123,7 @@ PyObject* BinaryMul::operator()( Expression* first, double second ) return 0; Py_ssize_t end = PyTuple_GET_SIZE( first->terms ); for( Py_ssize_t i = 0; i < end; ++i ) // memset 0 for safe error return - PyTuple_SET_ITEM( terms.get(), i, 0 ); + PyTuple_SetItem( terms.get(), i, 0 ); for( Py_ssize_t i = 0; i < end; ++i ) { PyObject* item = PyTuple_GET_ITEM( first->terms, i ); Replacing the macro with the function version seems to allow the extension to compile.
This seems related to #92898
