I have been trying to get the Boost libraries compiled on my mac for iPhone development.  I specifically want the math libraries.  I have found the needed boost.sh build script that has been provided by other tinkerers and that has worked pretty good.  It is just a wrapper around the regular boost build system.  When I tell that script that I want the math library, it runs the build script and then looks for the library &quot;libboost_math&quot;.  Unfortunately, after the build is completed (only requesting the math library), there are four math libraries present:<div>

<br></div><div>libboost_math_c99.a</div><div>libboost_math_c99f.a</div><div>libboost_math_tr1.a</div><div>libboost_math_tr1f.a</div><div><br></div><div>The iPhone build script then fails because there is no &quot;libboost_math.a&quot; library.  After the build should these be the final libraries?  Did my build fail to complete and I just did not know it?</div>

<div><br></div><div>I am running this on OSX Snow Leopard with the latest XCode (4.4.1 I think).  The build instructions that I have tried to follow are at:</div><div><br></div><div><a href="http://www.danielsefton.com/2012/03/building-boost-1-49-with-clang-ios-5-1-and-xcode-4-3/" target="_blank" style="color:rgb(17,85,204);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">http://www.danielsefton.com/2012/03/building-boost-1-49-with-clang-ios-5-1-and-xcode-4-3/</a></div>

<div><br></div><div>I did determine that I had to modify the boost.sh script to put &quot;pch=off&quot; on the build lines to get the math library to compile...</div><div><br></div><div>I would paste the output of the script but I am currently at work and do not have my personal computer in front of me.  This is more of a general build concept question.</div>
