::I guess. But since there are multiple different ways to output the message, I think it should be mentioned in each implementation, where and how the message will appear. --[[User:PauliKL|PauliKL]] 09:19, 28 October 2008 (UTC) |

This is the second fragment of Obj-C code that I try to run without success!! :) First, it is not a complete example (copy-pasting and simply compiling won't work...). Ok, I could try to complete the code... I obtained |
|||
<pre>#import <AppKit/AppKit.h> |
|||
int main() |
|||
{ |
|||
NSAlert *alert = [[[NSAlert alloc] init] autorelease]; |
|||
[alert setMessageText: @"Goodbye, World!"]; |
|||
[alert runModal]; |
|||
}</pre> |
|||
After "several" effort about understanding a NXConstantString vs NSConstantString problem, I succeeded compiling it with |
|||
<pre> |
|||
gcc -lobjc -fconstant-string-class=NSConstantString _box.m -lgnustep-gui -lgnustep-base -o box |
|||
</pre> |
|||
but running it, I obtain: |
|||
<pre>2008-12-09 15:39:11.749 box[9570] autorelease called without pool for object (80cf8c0) of class NSAlert in thread <NSThread: 0x8081690> |
|||
Segmentation fault |
|||
</pre> |

Ok this is not a place for debugging or what, but shouldn't the given codes work properly?! It seems not to work. --[[User:ShinTakezou|ShinTakezou]] 14:42, 9 December 2008 (UTC) |
