d2afa01f76
Update all appropriate version numbers as well as SHAs and MD5s as well
as repbasing BR's patches on top of 3.6.1 codebase (new github repo
tree, v3.6.1 tag was used). Note that patch:
[PATCH] Change the install location of _sysconfigdata.py
was dropped due to the fact taht build system now adds platform
specific suffix to sysconfigdata's name, so each platform's file
should have a unique name and distutils now allows to specify which
sysconfigdata is used via _PYTHON_SYSCONFIGDATA_NAME
see:
c4b53afce4
92dec548ff
and patches:
[PATCH] distutils/sysconfig: use sysconfigdata
[PATCH] setup.py: do not add invalid header locations
[PATCH] Do not harcode invalid path to ncursesw headers
was dropped since it looks like it made it's way upstream, see:
409482251b
1351c31aa9
e13c3201fb
respectively.

# Python package infrastructure
|
|
#
|
|
# This file implements an infrastructure that eases development of
|
|
# package .mk files for Python packages. It should be used for all
|
|
# packages that use Python setup.py/setuptools as their build system.
|
|
#
|
|
# See the Buildroot documentation for details on the usage of this
|
|
# infrastructure
|
|
#
|
|
# In terms of implementation, this Python infrastructure requires the
|
|
# .mk file to only specify metadata information about the package:
|
|
# name, version, download URL, etc.
|
|
#
|
|
# We still allow the package .mk file to override what the different
|
|
# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
|
|
# already defined, it is used as the list of commands to perform to
|
|
# build the package, instead of the default Python behaviour. The
|
|
# package can also define some post operation hooks.
|
|
