From e359a7a3c4f9e70360a068bef19c95938fdacede Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Date: Wed, 23 Dec 2015 11:33:14 +0100 Subject: [PATCH] Adjust library/header paths for cross-compilation When cross-compiling third-party extensions, the get_python_inc() or get_python_lib() can be called, to return the path to headers or libraries. However, they use the sys.prefix of the host Python, which returns incorrect paths when cross-compiling (paths pointing to host headers and libraries). In order to fix this, we introduce the _python_sysroot, _python_prefix and _python_exec_prefix variables, that allow to override these values, and get correct header/library paths when cross-compiling third-party Python modules.
