We currently have $(TARGET_DIR)/usr/lib/python$(PYTHON_VERSION_MAJOR)/site-packages/ inside the PYTHON_PATH variable, which gets used to define PYTHONPATH, passed to the host Python interpreter when building/installing target packages. However, this is terribly wrong, as it causes the host interpreter to potentially import target Python packages. This is wrong for several reasons: - Some Python packages might need some Python modules to be installed on the host (described in setup_requires in setup.py), but their installation currently works because by luck the corresponding Python module is installed for the target. Some of those cases were happening for real, and fixed by previous patches. - Some Python packages include some native code, therefore built for a specific CPU architecture. When you point the host Python interpreter to native libraries built for the target, you get nice build failures, such as the one affecting the python-cffi related packages. Making this change allows to fix the python-cffi related build failures: http://autobuild.buildroot.net/results/a9af84f2d845ee25e2b7d8b92aef485112b46060/ (python-cryptography) http://autobuild.buildroot.net/results/b017c4f6b4d45c0afbf06a80dbd3f2ebe5d49d20/ (python-pynacl) http://autobuild.buildroot.net/results/25144ea191ad46d851b31d3a2f0ef939f215494b/ (python-smbus-cffi) This change has been verified with the following defconfig that enables a lot of Python packages: BR2_arm=y BR2_TOOLCHAIN_EXTERNAL=y BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y BR2_TOOLCHAIN_EXTERNAL_URL="http://autobuild.buildroot.org/toolchains/tarballs/br-arm-full-2017.05-834-gb595627.tar.bz2" BR2_TOOLCHAIN_EXTERNAL_GCC_4_9=y BR2_TOOLCHAIN_EXTERNAL_HEADERS_3_10=y BR2_TOOLCHAIN_EXTERNAL_LOCALE=y BR2_TOOLCHAIN_EXTERNAL_CXX=y BR2_INIT_NONE=y BR2_SYSTEM_BIN_SH_NONE=y BR2_PACKAGE_PYTHON=y BR2_PACKAGE_PYTHON_ALSAAUDIO=y BR2_PACKAGE_PYTHON_ARROW=y BR2_PACKAGE_PYTHON_ATTRS=y BR2_PACKAGE_PYTHON_AUTOBAHN=y BR2_PACKAGE_PYTHON_BITSTRING=y BR2_PACKAGE_PYTHON_BOTTLE=y BR2_PACKAGE_PYTHON_CAN=y BR2_PACKAGE_PYTHON_CBOR=y BR2_PACKAGE_PYTHON_CHARDET=y BR2_PACKAGE_PYTHON_CHEETAH=y BR2_PACKAGE_PYTHON_CHERRYPY=y BR2_PACKAGE_PYTHON_CONFIGOBJ=y BR2_PACKAGE_PYTHON_CONFIGSHELL_FB=y BR2_PACKAGE_PYTHON_CRC16=y BR2_PACKAGE_PYTHON_CRCMOD=y BR2_PACKAGE_PYTHON_CSSSELECT=y BR2_PACKAGE_PYTHON_CSSUTILS=y BR2_PACKAGE_PYTHON_DAEMON=y BR2_PACKAGE_PYTHON_DIALOG=y BR2_PACKAGE_PYTHON_DICTTOXML=y BR2_PACKAGE_PYTHON_DJANGO=y BR2_PACKAGE_PYTHON_DOCOPT=y BR2_PACKAGE_PYTHON_DPKT=y BR2_PACKAGE_PYTHON_ECDSA=y BR2_PACKAGE_PYTHON_ENUM=y BR2_PACKAGE_PYTHON_FLASK_BABEL=y BR2_PACKAGE_PYTHON_FLASK_JSONRPC=y BR2_PACKAGE_PYTHON_FLASK_LOGIN=y BR2_PACKAGE_PYTHON_FLUP=y BR2_PACKAGE_PYTHON_GOBJECT=y BR2_PACKAGE_PYTHON_GUNICORN=y BR2_PACKAGE_PYTHON_HTML5LIB=y BR2_PACKAGE_PYTHON_HTTPLIB2=y BR2_PACKAGE_PYTHON_HUMANIZE=y BR2_PACKAGE_PYTHON_ID3=y BR2_PACKAGE_PYTHON_INIPARSE=y BR2_PACKAGE_PYTHON_IOWAIT=y BR2_PACKAGE_PYTHON_IPADDR=y BR2_PACKAGE_PYTHON_IPY=y BR2_PACKAGE_PYTHON_IPYTHON=y BR2_PACKAGE_PYTHON_JSON_SCHEMA_VALIDATOR=y BR2_PACKAGE_PYTHON_KEYRING=y BR2_PACKAGE_PYTHON_LIBCONFIG=y BR2_PACKAGE_PYTHON_LMDB=y BR2_PACKAGE_PYTHON_LXML=y BR2_PACKAGE_PYTHON_MAD=y BR2_PACKAGE_PYTHON_MARKDOWN=y BR2_PACKAGE_PYTHON_MELD3=y BR2_PACKAGE_PYTHON_MISTUNE=y BR2_PACKAGE_PYTHON_MSGPACK=y BR2_PACKAGE_PYTHON_MUTAGEN=y BR2_PACKAGE_PYTHON_MWSCRAPE=y BR2_PACKAGE_PYTHON_NETADDR=y BR2_PACKAGE_PYTHON_NETIFACES=y BR2_PACKAGE_PYTHON_NFC=y BR2_PACKAGE_PYTHON_NUMPY=y BR2_PACKAGE_PYTHON_PAHO_MQTT=y BR2_PACKAGE_PYTHON_PAM=y BR2_PACKAGE_PYTHON_PARAMIKO=y BR2_PACKAGE_PYTHON_PILLOW=y BR2_PACKAGE_PYTHON_POSIX_IPC=y BR2_PACKAGE_PYTHON_PSUTIL=y BR2_PACKAGE_PYTHON_PUDB=y BR2_PACKAGE_PYTHON_PYCLI=y BR2_PACKAGE_PYTHON_PYCPARSER=y BR2_PACKAGE_PYTHON_PYELFTOOLS=y BR2_PACKAGE_PYTHON_PYFTPDLIB=y BR2_PACKAGE_PYTHON_PYGAME=y BR2_PACKAGE_PYTHON_PYGAME_IMAGE=y BR2_PACKAGE_PYTHON_PYGAME_EXAMPLES=y BR2_PACKAGE_PYTHON_PYGAME_FONT=y BR2_PACKAGE_PYTHON_PYGAME_MIXER=y BR2_PACKAGE_PYTHON_PYINOTIFY=y BR2_PACKAGE_PYTHON_PYLIBFTDI=y BR2_PACKAGE_PYTHON_PYMYSQL=y BR2_PACKAGE_PYTHON_PYPARTED=y BR2_PACKAGE_PYTHON_PYPCAP=y BR2_PACKAGE_PYTHON_PYQRCODE=y BR2_PACKAGE_PYTHON_PYRATEMP=y BR2_PACKAGE_PYTHON_PYRO=y BR2_PACKAGE_PYTHON_PYROUTE2=y BR2_PACKAGE_PYTHON_PYSENDFILE=y BR2_PACKAGE_PYTHON_PYSMB=y BR2_PACKAGE_PYTHON_PYSNMP_APPS=y BR2_PACKAGE_PYTHON_PYSNMP_MIBS=y BR2_PACKAGE_PYTHON_PYSOCKS=y BR2_PACKAGE_PYTHON_PYTABLEWRITER=y BR2_PACKAGE_PYTHON_PYTRIE=y BR2_PACKAGE_PYTHON_PYUSB=y BR2_PACKAGE_PYTHON_PYXB=y BR2_PACKAGE_PYTHON_PYZMQ=y BR2_PACKAGE_PYTHON_REQUESTS_TOOLBELT=y BR2_PACKAGE_PYTHON_RPI_GPIO=y BR2_PACKAGE_PYTHON_RTSLIB_FB=y BR2_PACKAGE_PYTHON_SDNOTIFY=y BR2_PACKAGE_PYTHON_SERIAL=y BR2_PACKAGE_PYTHON_SETPROCTITLE=y BR2_PACKAGE_PYTHON_SH=y BR2_PACKAGE_PYTHON_SHUTILWHICH=y BR2_PACKAGE_PYTHON_SIMPLEJSON=y BR2_PACKAGE_PYTHON_SMBUS_CFFI=y BR2_PACKAGE_PYTHON_SOCKETIO=y BR2_PACKAGE_PYTHON_SORTEDCONTAINERS=y BR2_PACKAGE_PYTHON_SPIDEV=y BR2_PACKAGE_PYTHON_THRIFT=y BR2_PACKAGE_PYTHON_TOMAKO=y BR2_PACKAGE_PYTHON_TREQ=y BR2_PACKAGE_PYTHON_U_MSGPACK=y BR2_PACKAGE_PYTHON_UBJSON=y BR2_PACKAGE_PYTHON_UJSON=y BR2_PACKAGE_PYTHON_URLLIB3=y BR2_PACKAGE_PYTHON_VERSIONTOOLS=y BR2_PACKAGE_PYTHON_WATCHDOG=y BR2_PACKAGE_PYTHON_WEB2PY=y BR2_PACKAGE_PYTHON_WEBPY=y BR2_PACKAGE_PYTHON_WHOOSH=y BR2_PACKAGE_PYTHON_WS4PY=y BR2_PACKAGE_PYTHON_WSACCEL=y BR2_PACKAGE_PYTHON_XLUTILS=y Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Reviewed-by: Yegor Yefremov <yegorslists@googlemail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> |

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
