Perhaps he can give a bit more info. I do not understand how this could
break things, as the darwin code is earlier in the queue.
if os.name == "posix" and sys.platform == "darwin":
from ctypes.macholib.dyld import dyld_find as _dyld_find
def find_library(name):
possible = ['lib%s.dylib' % name,
'%s.dylib' % name,
'%s.framework/%s' % (name, name)]
for name in possible:
try:
return _dyld_find(name)
except ValueError:
continue
return None
if sys.platform.startswith("aix"):
# AIX has two styles of storing shared libraries
# GNU auto_tools refer to these as svr4 and aix
# svr4 (System V Release 4) is a regular file, often with .so as suffix
# AIX style uses an archive (suffix .a) with members (e.g., shr.o,
libssl.so)
# see issue#26439 and _aix.py for more details
from ctypes._aix import find_library
elif os.name == "posix":
# Andreas Degert's find functions, using gcc, /sbin/ldconfig, objdump
import re, tempfile
def _findLib_gcc(name):
As I understand the code above (and maybe I am wrong) - the code should
be calling the unchanged routines in the macholib subdirectory. A simple
test on macOS would be to comment out the two lines
if sys.platform.startswith("aix"):
from ctypes._aix import find_library
That will "delete" the AIX find_library logic.
In other words - can someone check whether the unchanged
Lib/ctypes/macholib/* files are being used? And if not, then something
surprising is preventing that. If they are - no idea how the macholib
code got effected by this. The goal was to have all changes in the
_aix.py file, rather than in util.py.
