|When I include the header files from two different classes into a third class,

|messages similar to the following:
|
|
|main2.m:18: warning: multiple declarations for method `init:'
|/Clib/RP.h:32: using `-init:(int )pSize'
|/Clib/RS.h:31: also found `-init:(OBJPTR )s'

The problem is that the compiler doesn't know which init: to use.  It
must either know the type of the receiver or the two methods must have
identical types.

|use, sometimes not, and sometimes it resolves it to the wrong init:.
|
|
|The code that has the init method is sililar in form to:
|
|	#import <RP.h>	// Both RP and RS have and init: method
|	#import <RS.h>
|
|	id x;
|
|	x = [[RP alloc] init:(int) 5];
|
|id is totally dynamic, and thus it really does not know which init to use....
|
|So, why is it telling me that it is using one method or another...shouldn't  
|this be left up until run-time? 

Yes, it should, but the compiler must generate code which is
equivalent to a function call.  To do this, it must know the types of
the arguments.  Since the types are different in this case, it doesn't
know what to generate.

|
|
|Am I doing something wrong to cause this?
|
|

Yes, you are.
