macOS which XCode tool to use?

[myjay610]

Hi all,

I've spent years programming in C/C++ but using Visual Studio or just gcc via command line. Now I have a need to use some of the APIs included with OS X. Do I need to pick a particular tool for this?

I first tried the C++ tool and I only need to use the Security/Security.h library for some keychain APIs. I try calling a simple function like SecKeychainGetVersion and I get collect2: ld returned 1 exit status, symbol(s) not found, "_SecKeychainGetVersion",referenced from:

I've included the header file as needed so I really don't know what's going on.

Thanks!
John

Did you include the framework too?

I've included CoreFoundation, Security, and CoreServices. I saw those included on a sample program I found somewhere.

You have to actually add the framework to the project to link against it, not just include the header files.

Just right-click on the Frameworks and Libraries group in the project window and select Add -> Existing Frameworks... and go to the System -> Library -> Frameworks folder and select the Security.framework and the other frameworks you included the headers for.

Then build and run it again.

Perfect, works now! Thanks!
