   4 Subject: [PATCH] Fix get_python_inc() for cross-compilation
   5
   6 When we are cross compiling, doing os.path.dirname(sys.executable) to
   7 get the build directory is incorrect, because we're executing the host
   8 Python to build things for the target. Instead, we should use the
   9 project_base variable.
  10
  11 This fixes cross-compilation, which was adding incorrect header paths
  12 pointing to the location where the host Python was built:
  13
  14 /home/thomas/projets/buildroot/output/host/usr/bin/arm-none-linux-gnueabi-gcc -fPIC -fno-strict-aliasing \
  15   -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -pipe -Os -DNDEBUG -g -O3 -Wall -Wstrict-prototypes \
  16   -I/usr/include -I. -IInclude -I./Include -I/home/thomas/projets/buildroot/output/host/usr/arm-buildroot-linux-gnueabi/sysroot/usr/include \
  17   -I/home/thomas/projets/buildroot/output/host/usr/bin/Include -I/home/thomas/projets/buildroot/output/host/usr/bin \
  18   -c /home/thomas/projets/buildroot/output/build/python-2.7.6/Modules/_struct.c \
  19   -o build/temp.linux2-arm-2.7/home/thomas/projets/buildroot/output/build/python-2.7.6/Modules/_struct.o
  20
  21 This patch allows to fix the
  22 /home/thomas/projets/buildroot/output/host/usr/bin/Include and
  23 /home/thomas/projets/buildroot/output/host/usr/bin paths that are
  24 incorrectly added to the header paths.
