Which again points to problems with
sysconfig.get_config_var("CONFIG_ARGS"):
[The earlier call was with "__CONFIG_ARGS", for whatever difference that
makes.] It appears to be returning None instead of [] (or a populated
list).
In 3.2.2, at line 579 of sysconfig.py is
def get_config_var(name):
return get_config_vars().get(name)
That defaults to None if name is not a key in the dict returned by
get_config_vars(). My guess is that it always is and and the the value
is always a list for tested win/*nix/mac systems. So either setup.py has
the bug of assuming that there is always a list value for "CONFIG_ARGS"
or sysconfig.py has the bug of not setting it for os2, perhaps because
of a bug elsewhere.
At line 440 of sysconfig.py is
def get_config_var(*args):
global _CONFIG_VARS
if _CONFIG_VARS is None:
_CONFIG_VARS = {}
<code to populate _CONFIG_VARS, including>
if os.name in ('nt', 'os2'):
_init_non_posix(_CONFIG_VARS)
if args:
vals = []
for name in args:
vals.append(_CONFIG_VARS.get(name))
return vals
else:
return _CONFIG_VARS
At 456 is
def _init_non_posix(vars):
"""Initialize the module as appropriate for NT"""
# set basic install directories
...
"CONFIG_ARGS" is not set explicitly for any system anywhere in the file,
so I do not know how the call ever works.
using _init_posix() for 'os2' instead of _init_non_posix is the fix for
this.
sysconfig.py also needs the following changes:
