Stanford Engineering Everywhere CS106B C++ Libraries in XCode 4.6.2 - c++

Question

Like many others, I'm taking the CS106B class on iTunes and, although the class is old, I am attempting to use the Stanford C++ libraries that are current. They are found here: http://www.stanford.edu/class/cs106b/.
During the Build Phase of projects, I have inserted into "Link Binary with Libraries" the files "random.h" and "libStanfordCPPlib.a". When I do this, I get the following error messages:
Check dependencies
warning: skipping file '/Users/lewis/Documents/Think Like a Programmer/CS106/VotingSimulation/../../../Programming Abstractions/Assignment 1/Assignment1-xcode/0 - Warmup/StanfordCPPLib/random.h' (unexpected file type 'sourcecode.c.h' in Frameworks & Libraries build phase)
ld: warning: ignoring file /Users/lewis/Documents/Programming Abstractions/Assignment 1/Assignment1-xcode/0 - Warmup/StanfordCPPLib/libStanfordCPPLib.a, file was built for archive which is not the architecture being linked (x86_64): /Users/lewis/Documents/Programming Abstractions/Assignment 1/Assignment1-xcode/0 - Warmup/StanfordCPPLib/libStanfordCPPLib.a
Undefined symbols for architecture x86_64:
"randomChance(double)", referenced from:
_main in main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I am using Mac OS X 10.7.5 and XCode 4.6.2. I have set the Build Settings Base SDK to OS X 10.7 for both the Project and the Target.
It appears to me that the "libStanfordCPPlib.a" file may be an archive file that I have to unarchive before I can link the implementation code for the header files. Is this what I need to do, and if so, how do I do it? Am I doing something else wrong in linking the files?
I'm a noob and I'd appreciate help from anyone who has been successful in getting the current Stanford CS106B C++ libraries to work in XCode 4.6.2.

Answer 1

I just ran into this problem myself after upgrading to the newest version of xcode (ver. 5.0, OSX ver. 10.8.5).
Try switching the architecture of the project to 32-bit Intel (i386). The default is "Standard Architectures 64-bit Intel (x86_64)".

Answer 2

I'm currently using xcode 6.4 and trying to work through the cs 106b course work, I had the same issue of not being able to run the sample files and assignment files (can be found here btw http://web.stanford.edu/class/archive/cs/cs106b/cs106b.1136/ ). After changing the Architectures for both the Project and Target to 32-bit-intel as listed above I still received errors. I had to take the additional step of changing the OSX deployment target from 10.10 to 10.8 under the Project info.
This allowed the program to build but I received a notification that i needed to install the Java Runtime Environment, and there was no consult output. Installing this did not resolve the issue. I was only able to fully execute the code after installing the Java Development Kit. I am now able to compile all files for the course.
I hope this update helps more recent attempts to access this info.

I hope you've found an answer to your problem by now, but as I was suffering from a similar problem, trying to get xcode 5.1 to compile Warmup.cpp, I thought I'd post my solution for those others trying to get xcode to work with the cs106b libraries.
After struggling with xcode 5.1.1 and 5.0.2, I downloaded xcode 4.6.3 off of the apple dev site, www.developer.apple.com, and trashed the later versions. After installing 4.6.3, I still got errors, but after switching the Architecures for the Project and for the Target, to "32-bit-Intel", as messysaurus suggests, the warmupp.cpp compiled fine. Trying this same technique with xcode 5.1.1 and 5.0.2 yielded no results.
Hope this helps anyone else running into problems.
