* [Buildroot] [PATCH] uboot-tools: bugfix libfdt python build @ 2017-10-13 2:35 Matt Weber 2017-10-13 14:11 ` Thomas Petazzoni 0 siblings, 1 reply; 10+ messages in thread From: Matt Weber @ 2017-10-13 2:35 UTC (permalink / raw) To: buildroot The libfdt is using setup.py to perform the build of it's wrapper. This is being invoked with the system's python default vs the HOST_DIR's. This patch completes the uboot-tools source update to support an optional python intepreter override and for buildroot to supply that value when doing a host build.

I'm thinking the best option would be to define an optional SWIG variable providing an absolute path to the tool and include an update to the SWIG detection logic using it. Then Buildroot could support an option to enable the libftd in the menu and let that select python. This option would be applicable to host and/or target, as I noticed target uboot-tools was also failing just not as often. So the python intepretor path is still valid, but if the plan above sounds good, I'll rework and remove the unconditional dependency. -- Matthew L Weber / Pr Software Engineer Airborne Information Systems / Security Systems and Software / Secure Platforms MS 131-100, C Ave NE, Cedar Rapids, IA, 52498, USA www.rockwellcollins.com Note: Any Export License Required Information and License Restricted Third Party Intellectual Property (TPIP) content must be encrypted and sent to matthew.weber at corp.rockwellcollins.com. ^ permalink raw reply [flat|nested] 10+ messages in thread

I ended up with the following conclusions. 1) Need to bump both packages to 2017.9 which I noticed was already underway (Thanks Fabio). This removes part of this patch submission that fixed the python interpreter (already upstream after 9/3) 2) Need something like the following added respectively with the new *_PYTHON_DEFS variable added to the MAKE OPTS in both uboot and uboot-tools (package/uboot-tools.mk) # BR2_TARGET_UBOOT_NEEDS_PYLIBFDT enables python2/swig host dependencies # as part of uboot's dependencies, however that means they occur after # this package in the build sequence. We add them here conditionally, # to move them prior to this package if the option is selected. If # it isn't selected, we still need to pass a swig path so that the pkg's # logic to include the _libfdt.so target drops that target as the path isn't valid. HOST_UBOOT_TOOLS_PYTHON_DEFS = SWIG_TOOL="$(HOST_DIR)/bin/swig" ifeq ($(BR2_TARGET_UBOOT_NEEDS_PYLIBFDT),y) HOST_UBOOT_TOOLS_PYTHON_DEFS += PYTHON="$(HOST_DIR)/bin/python$(PYTHON_VERSION_MAJOR)" HOST_UBOOT_TOOLS_DEPENDENCIES += host-python host-swig endif (boot/uboot.mk) UBOOT_PYTHON_DEFS = SWIG_TOOL="$(HOST_DIR)/bin/swig" ifeq ($(BR2_TARGET_UBOOT_NEEDS_PYLIBFDT),y) UBOOT_PYTHON_DEFS += PYTHON="$(HOST_DIR)/bin/python$(PYTHON_VERSION_MAJOR)" UBOOT_DEPENDENCIES += host-python host-swig endif 3) I need to send a patch upstream to get the SWIG_TOOL variable used instead of a "which swig" currently used in the tools/Makefile to trigger the setup.py build of libfdt.so. This doesn't fix all versions of uboot, just uboot-tools or uboots newer then a version. Thus I wonder for the older uboot versions that still have a host system dependency requirement, we add something like below in the uboot.mk above the ifeq ($(BR2_TARGET_UBOOT_NEEDS_PYLIBFDT),y) # There is a flaw in the tools/Makefile with the swig # checking line added on 2017-05-27 (ee95d10b). It doesn't # use a variable which could be set to the $(HOST_DIR)/bin/swig. # Until this is resolved, depending on the uboot version, # there is still a host system requirement to have the following # packages installed (apt install swig libpython-dev). Otherwise # you have to always have uboot select swig/python to prevent a # build failure, or remove swig from your host system. If all those changes go well, it means no requirement to build python with any uboot unless you want libfdt. I plan to get the swig patch submitted uboot upstream this week and supersede this patch with a new patchset dependent on the 2017.9 bump. It will include the new MAKE OPT updates.

With that they cleaned up the tools having some default python/swig dependencies by having libfdt enabled in uboot kconfig. We'll still have to update the BR2_TARGET_UBOOT_NEEDS_PYLIBFDT option in the uboot package so that it includes providing the PYTHON path variable to the build. The upstream changes also removed the need for this patchset against uboot-tools fixing python and swig patch issues.
