I am trying to access a global variable defined in a framework from an
application. For example, I have a simple Cocoa framework that contains:
char *string[] = "Some String";
long value = 1234;
void Frame1Routine()
{
NSLog(@"Frame 1 message");
// code and stuff
}
Now in my application, I have added the framework to the project. I know
that the framework is getting included properly, because I can call
Frame1Routine from my application, and the NSLog message is printed.
Now, if within my application I declare:
extern char *string;
extern long value;
and try to reference them from my application, it crashes with:
FinalApp.app has exited due to signal 11 (SIGSEGV).
In fact that same error happens even if I try to access those "global"
variables from within the Frame1Routine!
As another piece of information, when I build the application, I get the
following linker warning:
warning prebinding disabled because dependent library:
(HOME)/Library/Frameworks/Frame1.framework/Versions/A/Frame1 is not prebound
How to I access "global" variables from outside (or even inside!) a
framework?
Is that linker warning of any concern?
Are these two related?
Thanks.
