Re: Linking frameworks does not work

[Andreas Fink]

could it simply be that your /etc/ld.so.conf setup does not include the needed paths to find SRFoundation framework or you didnt run ldconfig after installing/updating the shared library?

Hi Wolfgang,

Selectors do not count here. They are only resolved at runtime not a link time.
You would need an explicit reference to a class, function or global variable from your frameworks inside the code of the test application to have the linker include those libraries in the executable.

int main (int argc, const char **argv, char** env)

  {

   NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

   

   [NSApplication sharedApplication];

   

   controller = [[Controller  alloc] init];

   NSLog(@"controller %@", controller);

   [NSApp setDelegate:controller];

   

   [NSString stringByChaining:@"ass" count:3];

...

   [pool release];

   return NSApplicationMain (argc, argv);

}

Is this directly enough? The method NSString::stringByChaining:count:] is defined/implemented in my SRFoundation framework. When I do

make 

I get a resulting app and starting it leads to "NSString does not recognize selector stringByChaining:count: exception. When I instead build with

make shared=no

I get

...

/usr/bin/ld: cannot find -lSRFoundation

...

and buolding the app fails!???

Thanks,

 Andreas
