Do not look at host headers/libraries in cross-compile mode
|
||
|
|
|
||
|
|
When we are cross-compiling, setup.py should never look in /usr or
|
||
|
|
/usr/local to find headers or libraries. A later patch adds a
|
||
|
|
mechanism to tell setup.py to look in a specific directory for headers
|
||
|
|
and libraries.
|
||
|
|
|
||
|
|
Patch first written by Thomas Petazzoni
|
||
|
|
<thomas.petazzoni@free-electrons.com> for python2.7, and then ported
|
||
|
|
to python3.3 by Maxime Ripard <maxime.ripard@free-electrons.com>
|
||
