I am attempting to build Boost as follows:<br /><br />I&#39;m working on a Windows XP machine using GCC supplied by MinGW.  I&#39;ve downloaded Boost_1_40_0 and successfully built bjam.exe.  <br /><br />For a test, I&#39;ve switched to C:\Boost\boost_1_40_0\libs\python\example\quickstart  as instructed here:  http://www.boost.org/doc/libs/1_41_0/libs/python/doc/building.html<br /><br />When I execute   <br /><br />bjam.exe toolset=gcc --verbose-test test  or bjam.exe toolset=gcc --debug-configuration --verbose-test test<br /><br />I get this warning:<br /><br />WARNING: No python installation configured and autoconfiguration<br />         failed.  See http://www.boost.org/libs/python/doc/building.html<br />         for configuration instructions or pass --without-python to<br />         suppress this message and silently skip all Boost.Python targets<br /><br /><br />--debug-configuration output contains the following:<br /><br /><br />notice: [python-cfg] Configuring python...<br />notice: [python-cfg] Registry indicates Python 2.5 installed at &quot;C:\Python25\&quot;<br />notice: [python-cfg] Checking interpreter command &quot;python&quot;...<br />notice: [python-cfg] running command &#39;DIR /-C /A:S &quot;C:\Python25\python.exe&quot; 2&gt;&1&#39;<br />notice: [python-cfg] running command &#39;&quot;python&quot; -c &quot;from sys import *; print &#39;version=%d.%d\nplatform=%s\nprefix=%s\nexec_prefix=%s\nexecutable=%s&#39; % (version_info[0],version_info[1],platform,prefix,exec_prefix,executable)&quot; 2&gt;&1&#39;<br />notice: [python-cfg] ...does not invoke a working interpreter<br />notice: [python-cfg] Checking interpreter command &quot;C:\Python25\python&quot;...<br />notice: [python-cfg] running command &#39;DIR /-C /A:S &quot;C:\Python25\python.exe&quot; 2&gt;&1&#39;<br />notice: [python-cfg] running command &#39;&quot;C:\Python25\python&quot; -c &quot;from sys import *; print &#39;version=%d.%d\nplatform=%s\nprefix=%s\nexec_prefix=%s\nexecutable=%s&#39; % (version_info[0],version_info[1],platform,prefix,exec_prefix,executable)&quot; 2&gt;&1&#39;<br />notice: [python-cfg] ...does not invoke a working interpreter<br />notice: [python-cfg] No working Python interpreter found.<br />notice: [python-cfg] running command &#39;DIR /-C /A:S &quot;C:\Python25\python.exe&quot; 2&gt;&1&#39;<br />notice: [python-cfg] falling back to &quot;python&quot;<br />notice: [python-cfg] Details of this Python configuration:<br />notice: [python-cfg]   interpreter command: &quot;python&quot;<br />notice: [python-cfg]   include path: &quot;Include&quot;<br />notice: [python-cfg]   library path: &quot;\libs&quot;<br />notice: [python-cfg]   DLL search path: &quot;&lt;empty&gt;&quot;<br /><br /><br /><br />However, I have Python installed at C:\Python25 and there is indeed python.exe at C:\Python25\python.exe<br /><br />Also, C:\Python25 is in my PATH.<br /><br />Any help is greatly appreciated.<br /><br />-Kirk
