Ah, I think I'm beginning to understand the complexity. I have modified
the code so that it assumes that every defined function is also
exported:
def merge_information( global_ns, fname, runs_under_unittest=False ):
"""high level function - select the appropriate binary file parser and
integrates
the information from the file to the declarations tree. """
# If there is no shared library available for parsing, we just assume
# that all functions have been exported.
if fname is None:
return dict([ [f.name, f] for f in global_ns.calldefs() ])
but this actually includes lots of irrelevant stuff coming from other
included headers. You are right, parsing the actual shared library is
probably a good thing(tm).
I will concentrate on finding a good way to determine the path of a
shared library instead. At least under linux, it seems to be a good way
to parse the 'ldconfig -p' output...
Best,
-Nikolaus
