Importing an external library in xcode - C++

I am quiet a newbie in coding, so the answer is maybe very simple. I am starting a new C++ project on Xcode and I want to import an external library from another assignment: http://www.stanford.edu/class/cs106b/assignments/assn-0-narcissism-mac.zip

I want to use the libcs106.a library in new projects. When I manually import the file into my new project, and I start to #include the libraries (like simpio.h), I get this long list of 113 bugs:

Can someone let me know what's wrong with my program?

Thanks! J

The compiler is complaining about classes and methods that it can't find anywhere. They all sound quite familiar to me so I believe you need to add references to several Mac OS X frameworks in your Xcode project:

Carbon.framework

Cocoa.framework

QuickTime.framework

You can do so by right clicking on the project explorer and using the Add / Existing frameworks… command.

You might prefer to use the assignment 0 source code for Mac as a starting point instead, as the included Xcode project comes already configured, linking against the course utility library and referencing all needed frameworks.
