Boost Python hello 示例给出错误。

Question

我一直在尝试让 Boost.Python 运行。我正在按照此处提到的步骤进行操作

http://www.boost.org/doc/libs/1_50_0/libs/python/doc/tutorial/doc/html/python/hello.html

。但是，当我尝试从教程目录运行示例程序时，出现以下错误。也就是 hello.py 的 python 脚本被删除。我如何得到 2 个我似乎无法纠正的错误。

我的 Python 版本是

C:\boost_1_50_0\libs\python\example\tutorial>python
Python 3.3.0 (v3.3.0:bd8afb90ebf2, Sep 29 2012, 10:57:17) [MSC v.1600 64 bit (AM
D64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> python --version

我之前安装了 Python32 的旧版本，但它似乎一直在寻找它。我的 PYTHON_INLCUDE 和 PYTHON_LIBRARY 都指向新的 python 和 PATH 环境变量。

C:\boost_1_50_0\libs\python\example\tutorial> echo %python_lib%\
C:\Python33\libs\python33.lib\

C:\boost_1_50_0\libs\python\example\tutorial> echo %python_include%\
C:\Python33\include\

C:\boost_1_50_0\libs\python\example\tutorial>

为什么 hello.py 文件不断被删除:(以及什么系统税不正确

Answer 1

您必须设置配置您的 user-config.jam 文件。似乎 Boost.Python 只能找到您的 Python 3.2 版本。您将在主目录 (ECHO %HOMEDRIVE%%HOMEPATH%) 中找到 user-config.jam 文件，或者在 boost 根目录中搜索“user-config.jam”文件。

您必须按照以下方式修改此文件以供您使用（仅作为示例）：

MSVC 配置（如果您使用 MSVC）

# -------------------
# MSVC configuration.
# -------------------

# Configure msvc (default version, searched for in standard locations and PATH).
# using msvc ;

# Configure specific msvc version (searched for in standard locations and PATH).
using msvc : 10.0 : C:\\app\\tools\\MSVisualStudio2010\\VC\\bin\\cl.exe ;

和 Python 配置

# ---------------------
# Python configuration.
# ---------------------

# Configure specific Python version.
# using python : 3.1 : /usr/bin/python3 : /usr/include/python3.1 : /usr/lib ;

using python 
    : 2.5                   # Version
    : C:\\app\\tools\\Python25\\python.exe      # Python Path
    : C:\\app\\tools\\Python25\\include         # include path
    : C:\\app\\tools\\Python25\\libs            # lib path(s)
    : <define>BOOST_ALL_NO_LIB=1
    ;

我昨天在编译 Boost 1.53 时遇到了同样的问题（“命令的语法不正确”）。我可以通过编辑文件 tools/build/v2/tools/common.jam 来解决这个问题：
