New submission from Albert Zeyer: On MacOSX, when you build an ARC-enabled Dylib with backward compatibility for e.g. MacOSX 10.6, some unresolved functions like `_objc_retainAutoreleaseReturnValue` might end up in your Dylib.
Some reference about the issue: 1. http://stackoverflow.com/q/21119425/133374>. 2. http://osdir.com/ml/python.ctypes/2006-10/msg00029.html 3. https://groups.google.com/forum/#!topic/comp.lang.python/DKmNGwyLl3w Thus, RTLD_NOW is often not an option for MacOSX. This affects mostly `py_dl_open()` from ctypes. But it is also related how you set `dlopenflags` in `PyInterpreterState_New()`. I suggest to make RTLD_LAZY the default on MacOSX (or is there a good reason not to do?). Also, ctypes should have options for both RTLD_NOW and RTLD_LAZY so that both can be used. This is also consistent with the behavior of the [dl module](http://docs.python.org/2/library/dl.html). ---------- components: ctypes messages: 208226 nosy: Albert.Zeyer priority: normal severity: normal status: open title: ctypes._dlopen should not force RTLD_NOW versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20276> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
