Re: bug with objc runtime (on Windows): Solved!!

[Lloyd Dupont]

One thing which worr me slightly is: if I replace class_get_super_class(c) by [c superclass] I have a compiler warning: objcsharp.m: In function `objcsharp_get_super_class': objcsharp.m:11: warning: cannot find method objcsharp.m:11: warning: return type for `superclass' defaults to id it works but it seems unsafe/unsure/unmaintain/breakable! any idea of the proper code? ----- Original Message ----- From: Lloyd Dupont To: Lloyd Dupont ; GNUstep Discussion Sent: Thursday, May 19, 2005 11:02 AM Subject: Re: bug with objc runtime (on Windows): Solved!! It's a class initialization problem! if I use [c1 superclass] instead of class_get_super_class(c1) it works! now, that's annoying because [c1 superclass] is an undocumented call I'm not sure it would be always there.... any C runtime function work around? ----- Original Message ----- From: Lloyd Dupont To: GNUstep Discussion Sent: Thursday, May 19, 2005 10:47 AM Subject: bug with objc runtime (on Windows) I have a very simple ObjectiveC only program which reproduce my problem, a memory access violation after a simple lookup. Any idea what it could be?   the file are attached but I copy for you the code inline. It has this memory access violation problem while trying to display the name of the super class.... ------------------------------------------------------------------------------- #include <objc/objc-api.h> #include <Foundation/Foundation.h> #include <stdio.h> #include <stdlib.h> #include <windows.h>   #define DEBUG2(x, fmt) printf("(%s:%d):%s :%s = %" #fmt "\n", __FILE__, __LINE__, __FUNCTION__, #x, x)   main() {  LoadLibrary("Kernel32");  LoadLibrary("gnustep-base");    Class c1 = objc_get_class("NSAutoreleasePool");  DEBUG2(c1, p);  const char * n1 = class_get_class_name(c1);  DEBUG2(n1, s);    Class c2 = class_get_super_class(c1);  DEBUG2(c2, p);  const char * n2 = class_get_class_name(c2);  DEBUG2(n2, s);    return 0; }
