Compilation failure using numpy 2.0.0b1 #431
Description
I tried to compile Boost::Python 1.84 library against numpy==2.0.0b1, but I'm getting a compilation error:
libs/python/src/numpy/dtype.cpp:101:83: error: no member named 'elsize' in '_PyArray_Descr'
int dtype::get_itemsize() const { return reinterpret_cast<PyArray_Descr*>(ptr())->elsize;}

See related part of numpy documentation: https://numpy.org/devdocs/release/2.0.0-notes.html#descriptor-elsize-and-alignment-access
The new accessor
PyDataType_ELSIZEmust be used:PyDataType_ELSIZE(reinterpret_cast<PyArray_Descr*>(ptr()))jakirkham commentedon May 7, 2024

While fixed now, it doesn't seem possible to build any prior Boost release if NumPy 2.x is installed. Is it possible to disable just the NumPy part when building via the central

Boost 1.86.0 got released just a few days ago. Did this not make it in there?

It doesn't look like it :-(

@stefanseefeld what do we need to do to get this in the next Boost release? Is 1.86.1 an option?
