- It is known to work under 10.2.8 and 10.3 using Apple's gcc 3.3 compiler:
- </p>
- <pre class="programlisting"><span class="identifier">gcc</span> <span class="special">(</span><span class="identifier">GCC</span><span class="special">)</span> <span class="number">3.3</span> <span class="number">20030304</span> <span class="special">(</span><span class="identifier">Apple</span> <span class="identifier">Computer</span><span class="special">,</span> <span class="identifier">Inc</span><span class="special">.</span> <span class="identifier">build</span> <span class="number">1493</span><span class="special">)</span></pre>
- <p>
- Under 10.2.8 get the August 2003 gcc update (free at <a href="http://connect.apple.com" target="_top">http://connect.apple.com</a>).
- Under 10.3 get the Xcode Tools v1.0 (also free).
- </p>
- <p>
- Python 2.3 is required. The Python that ships with 10.3 is fine. Under 10.2.8
- use these commands to install Python as a framework:
- </p>
- <pre class="programlisting"><span class="special">./</span><span class="identifier">configure</span> <span class="special">--</span><span class="identifier">enable</span><span class="special">-</span><span class="identifier">framework</span>
- <span class="identifier">make</span>
- <span class="identifier">make</span> <span class="identifier">frameworkinstall</span></pre>
- <p>
- The last command requires root privileges because the target directory is
- <code class="computeroutput"><span class="special">/</span><span class="identifier">Library</span><span class="special">/</span><span class="identifier">Frameworks</span><span class="special">/</span><span class="identifier">Python</span><span class="special">.</span><span class="identifier">framework</span><span class="special">/</span><span class="identifier">Versions</span><span class="special">/</span><span class="number">2.3</span></code>. However,
- the installation does not interfere with the Python version that ships with
- 10.2.8.
- </p>
- <p>
- It is also crucial to increase the <code class="computeroutput"><span class="identifier">stacksize</span></code>
- before starting compilations, e.g.:
- </p>
- <pre class="programlisting"><span class="identifier">limit</span> <span class="identifier">stacksize</span> <span class="number">8192</span><span class="identifier">k</span></pre>
- <p>
- If the <code class="computeroutput"><span class="identifier">stacksize</span></code> is too small
- the build might crash with internal compiler errors.
- </p>
- <p>
- Sometimes Apple's compiler exhibits a bug by printing an error like the following
- while compiling a <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">python</span><span class="special">::</span><span class="identifier">class_</span><span class="special"><</span><span class="identifier">your_type</span><span class="special">></span></code>
- template instantiation:
- </p>
- <pre class="programlisting"><span class="special">.../</span><span class="identifier">inheritance</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">:</span><span class="number">44</span><span class="special">:</span> <span class="identifier">error</span><span class="special">:</span> <span class="identifier">cannot</span>
- <span class="keyword">dynamic_cast</span> <span class="error">`</span><span class="identifier">p</span><span class="char">' (of type `struct cctbx::boost_python::<unnamed>::add_pair*
- '</span><span class="special">)</span> <span class="identifier">to</span> <span class="identifier">type</span> <span class="error">`</span><span class="keyword">void</span><span class="special">*</span><span class="error">'</span> <span class="special">(</span><span class="identifier">source</span> <span class="identifier">type</span> <span class="identifier">is</span> <span class="keyword">not</span> <span class="identifier">polymorphic</span><span class="special">)</span>
- </pre>
- <p>
- We do not know a general workaround, but if the definition of <code class="computeroutput"><span class="identifier">your_type</span></code> can be modified the following
- was found to work in all cases encountered so far:
- </p>
- <pre class="programlisting"><span class="keyword">struct</span> <span class="identifier">your_type</span>
- <span class="special">{</span>
- <span class="comment">// before defining any member data</span>
