ASIHTTPREQUEST framework compile error when method is called / link error
===

I am trying to compile a project using the ASIHTTPREQUEST library. 

I followed the directions and linked to all the necessary libraries, and I get no errors that are not compile errors... I am allowed to try to compile the project. 


The problems only arise when I try to use this code in my .m 

<blockquote>
 
    NSURL *colorURL = [NSURL URLWithString:@"http://www.colourlovers.com/api/colors?format=json"];
    
 
    ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:colorURL];
    
    
    [request setDelegate:self];
    
  
    [request startAsynchronous];

I don't understand what this error means:

<blockquote>

Really lost... please help!!

PS: I looked at some other threads on stack overflow but they don't reference to the same error.
