/* We try to define Py_LIMITED_API before including Python.h.
|
||
|
|
|
||
|
|
Mess: we can only define it if Py_DEBUG, Py_TRACE_REFS and
|
||
|
|
Py_REF_DEBUG are not defined. This is a best-effort approximation:
|
||
|
|
we can learn about Py_DEBUG from pyconfig.h, but it is unclear if
|
||
|
|
the same works for the other two macros. Py_DEBUG implies them,
|
||
|
|
but not the other way around.
|
||
|
|
|
||
|
|
Issue #350 is still open: on Windows, the code here causes it to link
|
||
|
|
with PYTHON36.DLL (for example) instead of PYTHON3.DLL. A fix was
|
||
|
|
attempted in 164e526a5515 and 14ce6985e1c3, but reverted: virtualenv
|
||
|
|
does not make PYTHON3.DLL available, and so the "correctly" compiled
|
||
|
|
version would not run inside a virtualenv. We will re-apply the fix
|
||
|
|
after virtualenv has been fixed for some time. For explanation, see
|
||
|
|
issue #355. For a workaround if you want PYTHON3.DLL and don't worry
|
||
|
|
about virtualenv, see issue #350. See also 'py_limited_api' in
|
||
|
|
setuptools_ext.py.
