本文解决了在使用 VC++2008 编译 Boost 1.46 与 Python 3.2 时出现的错误，并提供了配置文件 user-config.jam 的修改建议。此外还涉及了 Boost.Log 和 Boost.Filesystem 版本不匹配的问题及解决方案。

There is one build error when building boost 1.46 + python 3.2 via VC++ 2008:

libs/python/src/converter/builtin_converters.cpp(436) : error C2664: 'PyUnicodeUCS2_AsWideChar' : cannot convert parameter 1 from 'PyUnicodeObject *' to 'PyObject *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

Solution: change libs/python/src/converter/builtin_converters.cpp(436)

      static std::wstring extract(PyObject* intermediate)
      {
          std::wstring result(::PyObject_Length(intermediate), L' ');
          if (!result.empty())
          {
              int err = PyUnicode_AsWideChar(
                  /*(PyUnicodeObject *)*/intermediate     // change this line, comment out the C style cast!!!
                , &result[0]
                , result.size());

              if (err == -1)
                  throw_error_already_set();
          }
          return result;
      }

Note: I also append the following to D:/opensource/boost_1_46_0/tools/build/v2/user-config.jam

I also need to modify the following line in D:/src/boost_1_46_0/libs/python/src/module.cpp

BOOST_PYTHON_DECL PyObject* init_module(PyModuleDef& moduledef, void(*init_function)())

Otherwise there is a link error:

error LNK2001: unresolved external symbol "__declspec(dllimport) struct _object * __cdecl boost::python::detail::init_module(struct PyModuleDef &,void (__cdecl*)(void))" (__imp_?init_module@detail@python@boost@@YAPAU_object@@AAUPyModuleDef@@P6AXXZ@Z)

boost.log is only compatible with boost.filesystem v2, but boost 1.46 is using boost.filesystem v3 by default.

compile-c-c++ bin.v2/libs/log/build/msvc-10.0/release/link-static/runtime-link-static/threading-multi/text_file_backend.obj

text_file_backend.cpp

./boost/log/detail/universal_path.hpp(46) : error C2039: 'external_string_type' : is not a member of 'boost::filesystem3::path'

The following command can be used to build boost.log.

bjam.exe --with-log --toolset=msvc stage --build-type=complete define=BOOST_FILESYSTEM_VERSION=2

I created a batch file to build the boost library.

rem call "%VS100COMNTOOLS%/../../vc/bin/vcvars32.bat"

call "%VS90COMNTOOLS%/../../VC/vcvarsall.bat"

cd /d D:/opensource/boost_1_46_0

echo Update D:/opensource/boost_1_46_0/tools/build/v2/user-config.jam

call bootstrap.bat

set ICU_PATH=D:/opensource/icu4c-4_6-src/icu

echo "build start" >> buildtime.txt

time /t >> buildtime.txt

bjam.exe --toolset=msvc stage --build-type=complete -sBZIP2_SOURCE=D:/opensource/bzip2-1.0.5 -sZLIB_SOURCE=D:/opensource/zlib-1.2.5 -sICU_PATH="D:/opensource/icu4c-4_4_1-Win32-msvc9/icu" >> msvc10.log

time /t >> buildtime.txt

echo "build finished" >> buildtime.txt

Use boost.log in DLL

When I am using boost.log in DLL, the Debug configuration will raise the following error:

---------------------------
