title: How to make boost.build use a specific compiler installation?
body: <p>I am trying to build boost 1.45 using a local GCC compiler installation. I can't make it use a different compiler command that the default "g++". Here what happened so far:</p>
  
  <p>In boost_1_45_0 source directory:</p>
  
  <pre><code>./bootstrap.sh --with-toolset=gcc --prefix=$INSTALL/boost-$TYPE
  </code></pre>
  
  <p>Then added the following line to "projct-config.jam":</p>
  
  <p>using gcc : 4.4.6 : [absolute path]/install/gcc-4.4.6/bin/g++ : ;</p>
  
  <pre><code>./bjam install --prefix=$INSTALL/boost-$TYPE
  </code></pre>
  
  <p>When bringing up the process list during building, I can see that the system's default compiler command g++ gets used.</p>
