I'm using Mac OS X 10.2.8, Project Builder Version 2.1 Component
versions
PB IDE:114.0 PB Core: 1120 ToolSupport:110.
The settings for Project Builder are the defaults, I changed nothing
when I first started the program.
In following the book, "Building Cocoa Application Step by Step",
Chapter 7, Delegation and Resizing, page 220, page 221, I get the
following warnings.
warning: implicit declaration function 'ltob'
warning: assignment makes pointer from integer without a cast
warning: type mismatch with previous implicit declaration
warning: previous implicit declaration of 'lbod'
warning: 'ltob' was previously implicitly declared to return 'int'
Build succeeded (5 warnings)

Controller.m: In function `-[Controller displayX]':
Controller.m:91: warning: implicit declaration of function `ltob'
Controller.m:91: warning: assignment makes pointer from integer without
a cast
Controller.m: At top level:
Controller.m:124: warning: type mismatch with previous implicit
declaration
Controller.m:91: warning: previous implicit declaration of `ltob'
Controller.m:124: warning: `ltob' was previously implicitly declared to
return `int'
The program runs fine, as far as I can tell.
I'm curious, how would I correct the program so that no warnings show
up.
Thanks,
george.
