How to install GCC Compiler on Mac OS-X?
Problem Description:
Often times, you need c or gcc compiler to compile open source projects in Mac OS X. The problem is Mac OS X doesn’t install the gcc compiler by default.
If you try to install or compile some projects that required c/gcc compiler, following errors message will be logged :
  1. configure: error: C compiler cannot create executables 
  2. configure: error: no acceptable C compiler found in $PATH

In terminal, type “gcc“, you will get message “command not found”.
$ gcc
-bash: gcc: command not found

Solution: First Way -->
To install gcc compiler on Mac OS X, you need to download and install “Command Line Tools for Xcode”, which is available in Apple’s developer page. See following steps :
  1. Register Apple Developer Account : Go to Apple Developer Login page and register your account or login with our existing account details.
  2. Command Line Tools for XCODE : In Apple developer page, “Developer Tools” category, find “Command Line Tools for Xcode“, choose your version and click on the xx.dmg file (file size is 100mb ++) to start the download.
  3. Installation: After .dmg file is downloaded, a small dialog will be prompted and show you this file – “Command Line Tools.mpkg“, just double click on it, follow the wizard guide to complete the installation. 
  4. Verification: After installation is completed, run “gcc -v” in terminal again. If everything fine, following output will be displayed.
mkyong$ gcc -v
Using built-in specs.
Target: i686-apple-darwin11
Configured with: {ignore long text…}
Thread model: posix
gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.9.00)

Done, the gcc version 4.2.1 is installed on Mac OS X successfully.

Solution: Second Way -->
  1. Open XCODE 4.3 and above
  2. Click Xcode-->Preferences
  3. Click on Download Tab --> Component --> Check and Install Now
  4. In list select Command Line Tools and Install. 
Done ....
Keep coding .... :)

WPF-MVVM: RelayCommand Implementation

By
In WPF if we are implementing MVVM pattern then we need to play with Command rather than Events. You can use ICommand interface to create each command class. Implementation of ICommand in a class gives you CanExecute(), Execute() methods which take part in the action performed by Command.   Rather than making Command Class for each Command we can implement a generic Relay Command to get Command. Below is a RelayCommand class that we will implement.   ///   <summary>      ///  To register commands in MMVM pattern      ///   </summary>      class   RelayCommands  :  ICommand     {          readonly   Action < object > _execute;          readonly   Predicate < object > _canExecute;  ...

.Net List with Changed event

By
Sometimes we need a List which can notify user when an item is added. Here is the way that you can implement a generic ArrayList which notifies user at the time of an element is added.   using  System; using  System.Collections; namespace  ArchiveData.Logging {    // A delegate type for hooking up change notifications.    public   delegate   void   ChangedEventHandler ( object  sender,  EventArgs  e);    public   class   ListWithChangedEvent  :  ArrayList   {      // An event that clients can use to be notified whenever the      // elements of the list change.      public   event   ChangedEventHandler  Changed;      public   object  NewlyAddedItem {...

What is DispatcherTimer in wpf?

By
DispatcherTimer When you want to set a timer working with GUI, you always come across threading problem. The problem is that if you want to send some changes to UI that is constantly/continuously changing then that will make your UI unresponsive or in other words it will hang your UI.   To overcome from this situation, WPF gives us DispatcherTimer threading functionality that will take care of such continuously changing processing on UI thread and that will not hang your UI. We can accomplish same scenario in Win Form , through System.Windows.Forms.Timer and in WPF it is System.Windows.Threading.DispatcherTimer .   Difference between DispatcherTimer and Regular timer (System.Timers.Timer) DispatcherTimer is the regular timer. It fires its Tick event on the UI thread, you can do anything you want with the UI. System.Timers.Timer is an asynchronous timer, its Elapsed event runs on a thread pool thread. You have to be very careful in your event handler...
