It was reported by Miao Yan that the kconfig-related Python scripts are not working on Python 2.4.
Do we have any consensus in terms of Python version requirement?
This series avoids using "with ... as ..." and "except ... as ..." statements. But "with ... as ..." is used everywhere in buildman, which means buildman requires at least Python 2.6.
Hmmmm.... Funny... a bit more fire:
-------------------cut---------------------------- $ make cm_t335_defconfig HOSTCC scripts/basic/fixdep GEN /home/grinberg/bin-temp/u-boot/Makefile File "/home/grinberg/git-repo/u-boot/scripts/multiconfig.py", line 344 print "*** Default configuration is based on '%s'" % KBUILD_DEFCONFIG ^ SyntaxError: invalid syntax make[1]: *** [cm_t335_defconfig] Error 1 make: *** [sub-make] Error 2
$ python --version Python 3.3.5 -------------------cut----------------------------
Sorry, the script does not work on 3.x
I think make PYTHON=python2 cm_t335_defconfig will work if Python 2.x exists as "python2" in your command path.
Apparently, print should be used as function - with parenthesis...
Yes, a famous difference between 2.x and 3.x "print" is a statement in 2.x but a function in 3.x.
At first, when I was writing tools/genboardscfg.py, I tried to make it compatible with both 2.x and 3.x.
But I found it was more difficult than I had expected because of the varous differences. Finially I gave up.
As for scripts/multiconfig.py, perhaps I can modify it for 3.x compatible.
It seems that those scripts only work on Python versions 2.6 - 2.7?
Yes.
It is true we hope tools can work on broad range of versions, but it also means we have more restrictions when writing Python scripts.
I have no idea which version we should expect at least. Your comments are welcome.
I'd propose to not bring any new dependency on python at all... At least not for the simple task of building U-Boot... Can't we use a bit more stable API then this of python?
Yeah, some people want to run it on older version such as 2.4.x and some people want to use Python 3.x.
Now I found it so difficult to satisfy everyone. Maybe I made a mistake in the first place.
