Greetings:
I can't get gdb>po <object> to return a value from a simple NS object, other than NSXML objects.
I suspect it has something to do with the Intel chip; since I had no problem on my G4/G3 machines.
I made sure that all optimization was off; and I tried using Xcode 2.3+ version.
For example, I've created a simple NSString object, but I can't reveal it's value
using gdb>po. What I get is "Cannot Access Memory Address" as shown below.
My environment:
MacBook Pro on Intel running Leopard (10.5.1)
------------------------------------------------------
XCode & Debugger:
Using Xcode 3
Component versions
Xcode IDE: 921.0
Xcode Core: 921.0
ToolSupport: 893.0
Debug Information Format: DWARF
Optimization Level: none[-o0]
===========================================
-(void)awakeFromNib {
NSLog(@"{awakeFromNib}");
NSXMLElement *root = (NSXMLElement *)[NSXMLNode elementWithName:@"addresses"];
xmlDoc = [[NSXMLDocument alloc] initWithRootElement:root];
[xmlDoc setVersion:@"1.0"];
[xmlDoc setCharacterEncoding:@"UTF-8"];
// The following NSXMLElement generates a parent. Hence you can't add it to root.
NSXMLElement *xmlNoodle;
[xmlNoodle setName: @"RicNode"];
[xmlNoodle setStringValue:@"Pumpkin"]; // Note: this node has a parent; hence can't use "addChild".
[xmlNoodle attributeForName:@"Spanky"];
NSString *myString = [NSString stringWithString:@"Hello World!"]; <--- I can't see this. ********
