I have download the source from https://github.com/ResultsDirect/LinkedIn-iPhone . Demo working fine, and try to use in my application.
I have followed all the steps already whatever required as mention here in post ...
But I have getting the error
"_OBJC_CLASS_$_RDLinkedInEngine", referenced from:
"_OBJC_CLASS_$_RDLinkedInAuthorizationController", referenced from:
When I comment the lines of RDLinkedInEngine and RDLinkedInAuthorizationController then error are removed
- (void)loadView {
[super loadView];
// rdEngine = [[RDLinkedInEngine engineWithConsumerKey:kOAuthConsumerKey consumerSecret:kOAuthConsumerSecret delegate:self] retain];
}
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
// if( !rdHasAppeared ) {
// UIViewController* controller = [RDLinkedInAuthorizationController authorizationControllerWithEngine:rdEngine delegate:self];
// if( controller ) {
// [self presentModalViewController:controller animated:YES];
// rdHasAppeared = YES;
// }
// else {
// NSLog(#"Already authenticated");
// }
// }
}
I my application I have already integrated MGTwitterEngine from source https://github.com/bengottlieb/Twitter-OAuth-iPhone Which is wokring ok.

most probably you need to add some static library (.a file)... or src folder itself from linkedIn source...
I have gone through the same issue. It can be solved by setting Library Dependency. Select project target and then select general. There you will find Direct dependencies. Add LinkedInLibrary from LinkedInClientLibrary.xcodeProject

I am attempting to compile a simple application that references GNUstep classes, with GNUstep on my Ubuntu 14.04, 64 bit, machine:
#import <Foundation/Foundation.h>
#import <Cocoa/Cocoa.h>
int main(int argc, char **argv)
{
NSString *bestType = [[NSPasteboard generalPasteboard]
availableTypeFromArray: nil];
NSLog(#"best type: %#", bestType);
return 0;
}
Here are my compile and link flags (some of which may be overkill):
CFLAGS=`gnustep-config --objc-flags` -std=gnu99
LDFLAGS=`gnustep-config --base-libs` -lgnustep-base -lobjc -lm -lglut -lGLU -lGL
Before compilation I ran the script:
/usr/share/GNUstep/Makefiles/GNUstep.sh
And here is the output from 'make -n'
gcc main.m `gnustep-config --objc-flags` -std=gnu99 -L. `gnustep-config --base-libs` -lgnustep-base -lobjc -lm -lglut -lGLU -lGL -o tester
But when linking, Cocoa classes seem to not be pulled in, and I get an undefined reference error:
/tmp/ccnyXBoH.o:(.data.rel+0x8): undefined reference to `__objc_class_name_NSPasteboard'
If I remove all references to Cocoa classes in main.m, the app compiles without error.
The reason why you can't find the class definition for NSPasteboard is because it's in the gnustep-config --gui-libs options - i.e. the symbol is in the gui library of GNUStep, not in the base library of GNUStep. The solution is to change the LDFLAGS line to:
LDFLAGS=`gnustep-config --gui-libs` -lglut -lGLU -lGL
You shouldn't need to double-specify -lgnustep-base -lobjc -lm - they're part of both --base-libs and --gui-libs.
I created a react-native project using react-native init
I then add an action extension to that project using File -> new -> target -> Action Extension, with the name "Stash"
I try adding a StashView that inherits from UIView, and contains an RCTRootView, as instructed in the Integration with Existing App instructions:
Stash/StashView.h:
#import <UIKit/UIKit.h>
#interface StashView : UIView
#end
Stash/StashView.m:
#import "StashView.h"
#import "RCTRootView.h"
#implementation StashView
- (void)awakeFromNib {
NSString *urlString = #"http://localhost:8081/stash.ios.bundle";
NSURL *jsCodeLocation = [NSURL URLWithString:urlString];
RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
moduleName: #"Stash"
launchOptions:nil];
[self addSubview:rootView];
rootView.frame = self.bounds;
}
#end
When I compile, I get the error:
Undefined symbols for architecture x86_64:

What am I doing wrong? Something in the build settings?
Figured it out!
Based on the answer here
I had to open the Link Binary with Libraries carrot in the Build Phases of the extension, and add all of the react libraries to it:
The codes are like this:
#import <Foundation/Foundation.h>
#import <Cocoa/Cocoa.h>
int main(int argc, const char * argv[])
{
#autoreleasepool {
// insert code here...
NSLog(#"Hello, World!");
}
NSAlert *alert = [[NSAlert alloc] init];
[alert setMessageText:#"Hi there."];
[alert runModal];
return 0;
}
What I want is: when called from command line, this program pops up an alert box, when I close the alertbox. The program exits.
But when building, it complains like this:

When I choose the template for new project, I select command line tool instead of CoCoa Application as I just need CoCoa to display an alertbox. Does anyone have ideas about this..
That's because NSAlert is not #imported.
AppKit.h is not included by default when you create a command line tool , as you can see in the link, AppKit imports NSAlert.h.
EDIT:
First, to compile you need to add the Cocoa framework in your project.
Second, all the code should be enclosed in the #autoreleasepool section
#autoreleasepool {
// insert code here...
NSLog(#"Hello, World!");
NSAlert *alert = [[NSAlert alloc] init];
[alert setMessageText:#"Hi there."];
[alert runModal];
}
Your code will compile and run, but I think you'll have some other runtime errors.
I got the same error in C++ project that was using a NSAlert, this worked for me:
1) Adding
#include <Cocoa/Cocoa.h>
2) Adding Cocoa Framework in project->Buld Phases->Link Binary With Libraries.
3) Setting "Type" of all my .cpp files to "Objective-C++ Source" in the most right column in xCode.
you need to add this before main function
#import <AppKit/AppKit.h>
You need to import AppKit as mentioned by others and – as important as the framework – you need a run loop. So insert before the runModal line
[NSApplication sharedApplication];
to launch the "application" and the run loop
I have a class that holds number ivars:
// Answer.h
#import <Foundation/Foundation.h>
#interface Answer : NSObject{
#public
int firstNumber;
int secondNumber;
char myOperator;
}
#end
I try to access the code here
numberGroup->firstNumber = arc4random() % 1;
numberGroup->secondNumber = arc4random() % 10;
numberGroup->myOperator = arc4random() % 4;
and I get this error:

The compiler generates symbol _OBJC_IVAR_$_Answer.firstNumber in the data segment as part of the Answer class metadata when it processes the #implementation section for the Answer class. The data at that symbol is the offset of the firstNumber instance variable within an Answer object.
Either you aren't linking your app with a file that contains an #implementation Answer section, or the compiler hasn't seen the declaration of the firstNumber instance variable before it sees the #implementation Answer section. Check that these are all true:
Answer.m is included in your target's Compile Sources phase.
Answer.m contains an #implementation Answer section.
Answer.m imports Answer.h at the top of Answer.m.
I know how to compile the objective c program using gnustep version of mingw.
But I don't like their shell and I want to use the standard mingw gcc compiler.
I put this gcc bin directory in environment path of course, open command prompt in my helloworld.m directory
#import <Foundation/Foundation.h>
int main (int argc, const char * argv[])
{
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
NSLog (#"Hello World!");
[pool drain];
return 0;
}
and type
gcc -o hello hello.m -I /GNUstep/System/Library/Headers -L /GNUstep/System/Library/Libraries -lobjc -lgnustep-base -fconstant-string-class=NSConstantString
but it doesn't work because it cannot find foundation/foundation.h
How to fix this and if possible avoid hardcoding in hello source code ?
Have a look here at the end of the post the blogger says to write:
gcc `gnustep-config --objc-flags` -o hello2 hello2.m -L /GNUstep/System/Library/Libraries -lobjc -lgnustep-base
It seems like you always have to pass through GNUStep
I had the same problem.Modifying command line like below solved my problem.
gcc -I"c:/GNUstep/GNUstep/System/Library/Headers" -L "c:/GNUstep/GNUstep/System/Library/Libraries" -o hello hello.m -lobjc -lgnustep-base -fconstant-string-class=NSConstantString
