Hi,
I have the following problem. When I connect gdb to qemu for debugging it won't break on breakpoints. I can set breakpoints, break with ctrl-c etc.
Any clues how this can be fixed?
I have:

#include <iostream>
using namespace std;
int test() {
string a = "asd";
string b = "asd";
while…

Here's some output:
$ /usr/local/bin/gdb try1

I am writing a program in Objective-C (XCode 3.2, on Snow Leopard) that is capable of either selectively blocking certain sites for a duration or only allow certain sites (and thus block all others) for a duration. The reasoning behind this program is rather simple. I tend to get distracted when I…

Hi,
I made an Objective-C project for the iPhone. I had only one cpp class, the soundEngine taken from some Apple demo. Now I'm trying to merge OpenFeint which is coded in Objective-C++. As soon as I drop in the code without even referring to it from my code, when I hit Build, my Objective-C code…

Does anyone know of a way to add additional attribute types to the @property keyword without modifying the compiler? Or can anyone think of another way to genericize getter/setter creation?
Basically, I have a lot of cases in a recent project where it's handy for objects to lazily instantiate their…

I am developing an iPhone application and I use HTML to display formatted text.
I often display the same webpage, but with a different content. I would like to use a template HTML file, and then fill it with my diffent values.
I wonder if ObjectiveC has a template system similar to ERB in Ruby.
That…
