[Bf-committers] Moving to Python 3.2.x

[rsaavedra at ono.com]

Hi,
  I compile blender once o twice a week, but today I got this 
error:

#error "Python versions below 3.1 are not supported anymore, 
you'll need to update your python."

  That keep me wondering what the 
problem was, until I realized that in blender/python/intern/bpy_util.h 
there was this check:

#if PY_VERSION_HEX <  0x03020000
#error "Python 
versions below 3.1 are not supported anymore, you'll need to update 
your python."
#endif

  Please, someone fix the message :)

  By the 
way, I downloaded and compiled python 3.2 and then I had to put 
BF_PYTHON_VERSION = '3.2m' in user-config.py . 

  After that it 
copiled without problems and runned. I haven't tested blender yet to 
find if this  breaks anything.

to Python 3.2.x

Now we have Mac & Windows building with python 3.1 we 
can drop support
for all OS's.
For Linux this probably means you'll 
need to build your own since few
distributions support py3.2 yet.

I've 
updated the instructions for building python here.
http://wiki.blender.
org/index.php/Dev:2.5/Doc/Building_Blender/Linux/Troubleshooting#Python


note, since our wiki update the syntax highlighting has gone a strange

(since moving servers) so some text is easier to read when selected.


One gotcha with 3,.2 is that python now has a suffix which depends on

build-options so you may have libpython32mu.so or libpython32d.so,

where before it was simply libpython32.so.

>From ./configure.in
 * --
with-pydebug (adds a 'd')
 * --with-pymalloc (adds a 'm')
 * --with-
wide-unicode (adds a 'u')

This means getting the path to includes & 
libs isn't so simple
anymore, for linux it may be best to search for 
all possibly
combinations of d/m/u to detect the python version, but 
for now these
need to be set manually.
