Subject: [PATCH] Fix builds with Cython 3
|
||
|
|
|
||
|
|
This is a *de minimis* fix for building with Cython 3. Recent Cython<3
|
||
|
|
releases provided `Cython.Distutils.build_ext` as an alias to
|
||
|
|
`Cython.Distutils.old_build_ext.old_build_ext`; Cython 3 drops this
|
||
|
|
alias and instead uses a wholly new `Cython.Distutils.build_ext` that
|
||
|
|
does not provide the `cython_sources` function used in `setup.py`.
|
||
|
|
|
||
|
|
Explicitly importing `old_build_ext` preserves the existing behavior for
|
||
|
|
recent Cython<3 and uses the correct behavior for Cython 3. Should the
|
||
|
|
import fail (*e.g.*, because the version of Cython available predates
|
||
|
|
the availability of `old_build_ext`), the import falls back to just
|
||
|
|
`Cython.Distutils.build_ext`.
