Change the install location of _sysconfigdata.py
|
|
|
|
|
|
|
|
|
|
The _sysconfigdata.py module contains definitions that are needed when
|
|
|
|
|
building Python modules. In cross-compilation mode, when building
|
|
|
|
|
Python extensions for the target, we need to use the _sysconfigdata.py
|
|
|
|
|
of the target Python while executing the host Python.
|
|
|
|
|
|
|
|
|
|
However until now, the _sysconfigdata.py module was installed in
|
|
|
|
|
build/lib.<arch>-<version> directory, together with a number of
|
|
|
|
|
architecture-specific shared objects, which cannot be used with the
|
|
|
|
|
host Python.
|
|
|
|
|
|
|
|
|
|
To solve this problem, this patch moves _sysconfigdata.py to a
|
|
|
|
|
separate location, build/sysconfigdata.<arch>-<version>/, and only
|
|
|
|
|
this directory gets added to the PYTHONPATH of the host Python
|
|
|
|
|
interpreter when building Python modules for the target.
