    text
    copied!<p>So far as I can tell what happens is this:</p> <ul> <li>In <code>python.jam</code>, it works out which version of Python I am using and which library directories to look in;</li> <li>It adds <code>-Wl-R</code> arguments to the <code>g++</code> command line to include those directories;</li> <li>The <code>ld</code> command complains that it does not have a <code>-R</code> option.</li> </ul> <p>So either (a) I have a defective version of <code>ld</code>, or (b) I need to tell bjam that it needs to use a different option (<code>-rpath</code> perhaps?) or that this option is not required.</p> <p>I must be missing something—I am surely not the first person in history to try to build a Python extension with Boost on Mac OS X—but I can’t figure out where to look next. Any hints?</p> <p>Update:</p> <p>The command I am using is</p> <pre><code>bjam </code></pre> <p>If I do <code>bjam --version</code>, I get </p> <pre><code>Boost.Build V2 (Milestone 12) Boost.Jam 03.1.18 </code></pre> <p>The toolset used is whatever the default toolset is on Mac OS X.</p> <p>The compiler is the default compiler on Mac OS X (with the developer tools installed), which is GCC version ‘i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5664)’.</p> <p>The linker is the default linker on Mac OS X, which is called <code>ld</code> or <code>ld64</code>, but which does not have the <code>-R</code> option that GNU <code>ld</code> has, so I assume it is a special version designed to allow for Mac OS X’s concept of frameworks or whatever. It does not have a <code>--version</code> option.</p> <p>There is a <code>Jamfile</code>, which goes like this:</p> <pre><code>import python ; python-extension _optimor : bill_python.cpp bill_record_python.cpp .. etc ... : &lt;cxxflags&gt;-fPIC ... etc ... &lt;variant&gt;debug:&lt;define&gt;DEBUG &lt;include&gt;/usr/include/python2.6 &lt;include&gt;../ ; </code></pre> <p>It builds OK on Ububtu GNU/Linux.</p> <p>I am not interested in Boost or <code>bjam</code> per se; my only requirement to compile this extension so I can get on with developing the system of which this extension is a small but important part. </p>
