From 0ef0d4ddd3f2261e381f22061a9a451dfbb1dc9e Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Tue, 7 Mar 2017 22:17:59 +0100 Subject: [PATCH] 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.- 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.-/, and only this directory gets added to the PYTHONPATH of the host Python interpreter when building Python modules for the target.
