title: How to change the amount of building threads in Xcode?
body: <p>I'm building a couple of C++ files in xcode that take a lot of memory to compile (+1 GB / file). Because I do this on my dual core laptop, xcode uses 2 threads for building. The two threads will eventually be building the files that take a lot of memory simultaneously so the system suffers memory starvation and the compilation grinds to a near halt.</p>
  
  <p>A sufficient solution for me would be to force Xcode to use only one build thread. Does anybody know a way to change how many build threads Xcode uses?</p>
  
  <p>For those who are interested, the C++ files contain a sizable boost::spirit::qi parser.</p>
