Revision as of 15:57, 21 July 2020

In an effort to follow the Python2 deprecation on the 1st of January 2020, here is a listing of current Buildroot packages that depend on Python2 (as of master during the [developer days at FOSDEM 2020])

Non Python packages

These packages integrate with Python2: either they contain scripts written in Python, or they install Python libraries as byproducts.

Python packages

(TBD) These packages are Python libraries that can then be imported by Python scripts

Python in the build system

These packages use Python in their build process, hence requiring host-python (or host-python3). We aim at removing dependencies on host-python(2) where possible, and therefore remove conditionals such as illustrated below. This should instead unconditionnally depend on host-python3 now:

ifeq ($(BR2_PACKAGE_PYTHON)
FOO_DEPENDENCIES += host-python
else
FOO_DEPENDENCIES += host-python3
endif

At the moment, the following packages reference host-python(2)

  • ca-certificates
  • canfestival
  • host-dbus-python
  • host-gdb
  • gnuradio
  • gst1-validate
  • host-gtest
  • libimxvpuapi
  • libsigrock
  • libxcb
  • midori
  • nodejs
  • ogre
  • host-omniorb
  • qpid-proton
  • qt5webengine
  • qt5webkit
  • rust
  • sdbusplus
  • spidermonkey
  • tvheadend
  • webkitgtk
  • wpewebkit
  • xcb-proto, host-xcb-proto
  • zynq-boot-bin

waf

The waf-package infrastructure has been fully migrated to host-python3

Scons

All packages using SCons (no dedicated infrastructure) have been migrated to host-python3
