title: compile Boost as static Universal binary lib
body: <p>I want to have a static Universal binary lib of Boost. (Preferable the latest stable version, that is 1.43.0, or newer.)</p>
  
  <p>I found many Google hits with similar problems and possible solutions. However, most of them seems outdated. Also none of them really worked.</p>
  
  <p>Right now, I am trying</p>
  
  <pre><code>sudo ./bjam --toolset=darwin --link=static --threading=multi \
  --architecture=combined --address-model=32_64 \
  --macosx-version=10.4 --macosx-version-min=10.4 \
  install
  </code></pre>
  
  <p>That compiles and install fine. However, the produced binaries seems broken.</p>
  
  <pre><code>az@ip245 47 (openlierox) %file /usr/local/lib/libboost_signals.a
  /usr/local/lib/libboost_signals.a: current ar archive random library
  
  az@ip245 49 (openlierox) %lipo -info  /usr/local/lib/libboost_signals.a
  input file /usr/local/lib/libboost_signals.a is not a fat file
  Non-fat file: /usr/local/lib/libboost_signals.a is architecture: x86_64
  </code></pre>
  
  <p>Edit: It seems that the command was wrong and I must remove the "--" for most options. So the command I am trying now (-a just means to rebuild all):</p>
  
  <pre><code>sudo ./bjam -a toolset=darwin link=static threading=multi \
  architecture=combined address-model=32_64 \
  macosx-version=10.4 macosx-version-min=10.4 \
  install
  </code></pre>
  
  <p>However, this gives many strange errors (what I already had earlier), all like this:</p>
  
  <pre><code>darwin.compile.c++.pch bin.v2/libs/math/build/darwin-4.2.1/release/address-model-32_64/architecture-combined/link-static/macosx-version-min-10.4/macosx-version-10.4/threading-multi/../src/tr1/pch.hpp.gch

  ./boost/config/no_tr1/cmath.hpp:21:19: error: cmath: No such file or directory
  </code></pre>
  
  <p>This could be another problem I have when building Universal binaries: <a href="https://stackoverflow.com/questions/2830931/g-on-macosx-doesnt-work-with-arch-ppc64">g++ on MacOSX doesn&#39;t work with -arch ppc64</a></p>
