Sometimes I got problem settings breakpoints. I found this solution in apple discussions:
x
As saggymac said:
“The default setting for debugging libraries and frameworks is Load Symbols Lazily. On occasion this causes breakpoints to not be hit. Turning off this setting makes it take longer to start debugging, but hits breakpoints more reliably.”
may be you should set this option OFF… (XCode-Preferences-Debugging)

I am trying to compile a simple command line for experiment, and it is somehow not as obvious as I thought.

Here is a the very simple program I copied somewhere from internet

#import <Foundation/foundation.h>

int main( int argc, const char* argv[])
{
  NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

  NSObject *object = [[NSObject alloc] init];
  NSLog(@"Created Object: %@", object);

  [pool release];
  return 0;
}

and here is how to compile it :

gcc main.m -o main -ObjC -framework Foundation

setting “-framework Foundation” is the one that threw me off. I couldn’t find it anywhere !

First, to install nginx do this :

sudo port install nginx

then use this configuration - this is only for testing, with setting for my os x (for access log / pids). It also use proxy to merb

# nginx using macports installation
# for my local testing
user kusno staff;
worker_processes  1;

pid /opt/local/var/run/nginx.pid;
error_log  /opt/local/var/log/nginx/error.log  info;

events {
    worker_connections  16;
}

http {
  include        etc/nginx/mime.types;
  default_type   application/octet-stream;
  access_log /opt/local/var/log/nginx/access.log;
  sendfile        on;
  #tcp_nopush     on;
  keepalive_timeout  65;
  tcp_nodelay        on;
  gzip  on;
  gzip_min_length  1100;
  gzip_buffers     4 8k;
  gzip_types       text/plain;
  client_max_body_size 100m;

  upstream merb {
    server 127.0.0.1:4000;
  }

  server {
    listen       80;
    server_name  localhost;

    root /Users/kusno/ezify/public;

    index  index.html index.htm;

    location / {
      proxy_set_header  X-Real-IP  $remote_addr;
      proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_redirect false;
      #if (-f $request_filename/index.html) {
      #  rewrite (.*) $1/index.html break;
      #}
      #if (-f $request_filename.html) {
      #  rewrite (.*) $1.html break;
      #}
      if (-f $request_filename) {
        rewrite (.*) $1 break;
      }
      if (!-f $request_filename) {
        proxy_pass http://merb;
        break;
      }
    }
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }
  }
}

use this to restart nginx :

sudo launchctl stop org.macports.nginx
sudo launchctl start org.macports.nginx

I got a strange problem, and unable to play any kind of movies in my iPhone simulator. iPhone just gave a very unhelpful error messages - “The movie could not be played” if I try to play it from internet. Fortunately, if I play the movie locally, I can see some error message from the log :

[Session started at 2008-06-02 11:29:33 -0700.]
2008-06-02 11:29:43.933 TestMP[444:20b] forceGaplessRingtones = NO

  Expected in: /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator2.0.sdk/System/Library/Frameworks/SystemConfiguration.framework/Versions/A/SystemConfiguration

It might be caused by DivX decoder that I installed recently. After removing DivX Decoder & Encoder component from /Library/QuickTime, now I can play the movie locally.

But there is still another problem when I tried to play from internet - from my local server; it still won’t play the movies ! .. I tried to download it manually with firefox, and it seems like this is the problem with the mime type. After fixing mime types in the server, voila .. finally I am able to see it running in my iPhone
