From 367ee7d103cf9f670c3925d555edf6f6a5b9d8d5 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Tue, 7 Mar 2017 22:17:25 +0100 Subject: [PATCH] Fix get_python_inc() for cross-compilation When we are cross compiling, doing os.path.dirname(sys.executable) to get the build directory is incorrect, because we're executing the host Python to build things for the target. Instead, we should use the project_base variable. This fixes cross-compilation, which was adding incorrect header paths pointing to the location where the host Python was built: /home/thomas/projets/buildroot/output/host/usr/bin/arm-none-linux-gnueabi-gcc -fPIC -fno-strict-aliasing \ -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -pipe -Os -DNDEBUG -g -O3 -Wall -Wstrict-prototypes \ -I/usr/include -I. -IInclude -I./Include -I/home/thomas/projets/buildroot/output/host/usr/arm-buildroot-linux-gnueabi/sysroot/usr/include \ -I/home/thomas/projets/buildroot/output/host/usr/bin/Include -I/home/thomas/projets/buildroot/output/host/usr/bin \ -c /home/thomas/projets/buildroot/output/build/python-2.7.6/Modules/_struct.c \ -o build/temp.linux2-arm-2.7/home/thomas/projets/buildroot/output/build/python-2.7.6/Modules/_struct.o This patch allows to fix the /home/thomas/projets/buildroot/output/host/usr/bin/Include and /home/thomas/projets/buildroot/output/host/usr/bin paths that are incorrectly added to the header paths.
