[issue1531] Add OpenBSD specific paths to tkinter module.
by Edd Barrett Sept. 5, 2013

Sept. 5, 2013

New submission from Edd Barrett <vext01(a)gmail.com>: The following diff allows the recent Tk work to run on OpenBSD. Note that you need a threaded version of tcl for the pypy tk binding to function (is this intended? Cpython does not require a threaded version of tcl). I have left some XXX comments as questions to the devs. I am not sure if there is a better way to locate tk... Cheers ---------- files: pypy-tk.diff messages: 5912 nosy: pypy-issue, vext01 priority: wish status: unread title: Add OpenBSD specific paths to tkinter module. ________________________________________ PyPy bug tracker <tracker(a)bugs.pypy.org> <https://bugs.pypy.org/issue1531> ________________________________________

[issue1593] segfault with ctypes callback on OS X
by Florian Schulze Sept. 5, 2013

Sept. 5, 2013

New submission from Florian Schulze <florian.schulze(a)gmx.net>: When I run the code below I consistently get a segfault a few seconds after touching the trackpad with several fingers. Even if I do nothing inside the callback except "return 0" I get the segfault. It seems like MTDeviceStart spawns a new thread in which the callback is called.
