Ok, I give up. I searched the CVS code, and can't find the place that
turns an include_dirs option in setup.cfg into a list of
directories. The reason I was looking for it is that I can't figure
out how to make include_dirs include multiple directories from
setup.cfg. Everything I try winds up putting
-I<contents_of_i nclude_dirs>. I couldn't even find the place where the
string value that is returned by ConfigParser is enclosed in a list.
I did it this way:
% cd work/py2.4/Lib/distutils/
% grep setup.cfg *
dist.py: on Windows/Mac, and setup.cfg in the current directory.
dist.py: # All platforms support local setup.cfg
dist.py: local_file = "setup.cfg"
So it is clearly dist.py. There, setup.cfg is returned from
find_config_fil es. This is called a single time only in dist.py,
namely from parse_config_fi les. As you can see, this is then set
as the global include_dirs option. Apparently, include_dirs really
*is* a single string, then.
Now, where is it split into multiple substrings?
% grep include_dirs *.py */*.py
This gives a long list. However, in two places, include_dirs is split:
command/config.py: self.include_di rs =
string.split(se lf.include_dirs , os.pathsep)
command/build_ext.py: self.include_di rs =
string.split(se lf.include_dirs , os.pathsep)
Both places have similar code:
if self.include_di rs is None:
self.include_di rs = self.distributi on.include_dirs or []
elif type(self.inclu de_dirs) is StringType:
self.include_di rs = string.split(se lf.include_dirs , os.pathsep)
