hello.c:4: error: expected expression before '[' token
hello.c:4: error: 'NSWorkspace' undeclared (first use in this function)
hello.c:4: error: (Each undeclared identifier is reported only once
hello.c:4: error: for each function it appears in.)

Seems you targetering to iphone, so you have to use [[UIApplication sharedApplication] openURL] instead of NSWorkspace.

#import <Foundation/Foundation.h>

#if TARGET_OS_IPHONE
#import <UIKit/UIKit.h>
#endif

// ...

#if TARGET_OS_IPHONE
    [[UIApplication sharedApplication] openURL:url];
#elif TARGET_OS_MAC
    [[NSWorkspace sharedWorkspace] openURL:url];
#endif

And don't forget to add Foundation framework to include and link section.

If your are new to iOS programming I highly recommend using some of Apples templates in xCode as a basis for your development.

NSWorkspace is a MacOS X construct. I don't think there is any iOS equivalent.

Take a look at the CP193P videos on iTunesU to get you started on iOS programming - happy programming!

You have to

#import <Foundation/Foundation.h>

Also, the file name should be hello.m so that the compiler knows it deals with Objective-C here.

And make sure to link your binary to the Foundation framework.
