Fixes mesa3d build errors: http://autobuild.buildroot.net/results/d10/d105a0b3ca11fad34f9a2dae0dae9bd041d918a6/ http://autobuild.buildroot.net/results/d71/d7121443715024d15a66ff1abf1261803c10cd35/ http://autobuild.buildroot.net/results/ce6/ce64164d76972f82acab277afc9c95a876c6433e/ checking for python2... python2 checking python2 module: libxml2... no configure: error: failed to find required module libxml2 make: *** [/home/test/test/1/output/build/mesa3d-10.0.4/.stamp_configured] Error 1 mesa3d needs python2 bindings installed by libxml2. To enforce their build option BR2_PACKAGE_HOST_LIBXML2_PYTHON is used exclusively by mesa3d so this patch does not affect other packages. Without this patch host-libxml2 installs the python bindings in $(HOST_DIR)/usr/lib/$(PYTHON3_VERSION_MAJOR) using this defconfig: BR2_PACKAGE_MESA3D=y BR2_PACKAGE_PYTHON3=y because $(HOST_DIR)/usr/bin/python points to $(HOST_DIR)/usr/bin/python3: Quote from host-libxml2 configure log: Found python in /home/fli4l/br2/buildroot/output/host/usr/bin/python Found Python version 3.4 HOST_$(PACKAGE)_NEEDS_HOST_PYTHON does not work here because libxml2 does not use the python-package infrastructure. libxml2-python2.patch extends the python detection code in host-libxml2 to first look for python2, to keep the patch small I did not update the indentions: Found python2 in /home/fli4l/br2/buildroot/output/host/usr/bin/python2 Found Python version 2.7 Signed-off-by: Bernd Kuhls <bernd.kuhls@t-online.de> Tested-by: Samuel Martin <s.martin49@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
