[C++-sig] EXTERNAL: Building Boost Python problem

I'm attaching my notes below.  I will point out that while the directions reference 1.48, I've actually had problems with 1.48 and MinGW-W64.  Specifically, I'm having problems with bjam building all libraries at once.  Building individually appears to work, but I haven't bothered trying to build each one on its own yet.   I've inquired on boost-build, but haven't heard anything back.  Personally, I would recommend 1.47.  If you'd like the def file referenced in the instructions, shoot me a personal email and I'll forward it to you.  Keep in mind that you *cannot* use a 32-bit def file if you are using 64-bit Python.  I will also forewarn you there are other issues with x64 Python and MinGW-W64 if you plan on building extensions.  Take a look here: http://bugs.python.org/issue4709


---Building Boost for MinGW-----

h1. Building Boost

Building Boost for MinGw is the opposite of fun.  Here are some notes to get you through the misery.


h2. x64 Windows

*Directories*
* C:\TEMP\boost_1_48_0 - Where Boost source code was extracted
* c:\mingw64-i686-20110207 - 64-bit MinGw
* C:\Python26 - 64-bit Python installation (2.6.6)
* C:\TEMP\boost_build - Directory for storing build output

*Steps*
# Enter C:\TEMP\boost_1_48_0\tools\build\v2\engine
# C:\TEMP\boost_1_48_0\tools\build\v2\engine>build.bat mingw --toolset-root=c:\mingw64-i686-20110207

2.	There, locate the following code:

{
    # Prior to version 3.1.17 Boost Jam's SHELL command did not support
    # quoted commands correctly on Windows. This means that on that
    # platform we do not support using a Python command interpreter

Subject: EXTERNAL: [C++-sig] Building Boost Python problem

Hi I hope someone can help me out...
The object is to build boost python (boost-1.4.8, python 2.7 32bit, windows 7 64bit, mingw).
I've been trying to fix this for a good 8 hours but can't figure it out.

bjam --with-python --build-type=complete --toolset=gcc stage

Looking at the resulting output below, I see the problem is probably that bjam can't find python27.lib.  I just don't see how that is possible because it finds python.exe in C:\Python27 and indeed python27.lib exists in the C:\Python27\libs directory.

Resulting output.....
