New submission from jice <jice.nos...@gmail.com>: This code works in python 2.5 & 2.6 : >>> import ctypes >>> lib=ctypes.cdll['./libtcod.so'] >>> lib.TCOD_console_init_root(80,50,'test',0) 1
In python 3.0, it crashes in _CallProc (callproc.c, line 1136) : if (atypes[i]->type == FFI_TYPE_STRUCT atypes[i] == NULL here because when there is no argtypes, the default converter (ConvParam) does not set ffi_type for string parameters if HAVE_USABLE_WCHAR_T is FALSE. To make it work, I have to define the argtypes for the function : >>> import ctypes >>> lib=ctypes.cdll['./libtcod.so'] >>> from ctypes import * >>> lib.TCOD_console_init_root.argtypes=[c_int,c_int,c_char_p,c_uint] >>> lib.TCOD_console_init_root(80,50,'test',0) 1 I've compiled python 3.0 on a standard Ubuntu 8.04 and the test_ctypes unit test works fine. ---------- assignee: theller components: ctypes messages: 79334 nosy: jice, theller severity: normal status: open title: crash in ctypes when passing a string to a function without defining argtypes type: crash versions: Python 3.0 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4867> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
