需要帮助在Windows上为python27构建调试lxml

时间：2012-10-23 17:46:51

标签： python lxml

我正在调试由使用lxml的脚本导入的另一个dll。我需要从lxml项目创建一个objectify_d.pyd和etree_d.pyd。我按照这里的构建说明成功构建了这些：http://lxml.de/build.html但使用此命令：

python setup.py build --debug --static

我试过这样做：

python setup.py build --debug

但这没效果。

构建似乎成功了。创建了objectify_d.pyd和etree_d.pyd。使用这些文件（通过将它们复制到c：/ python27 / lib / site-packages / lxml /）并运行调试python构建，我在尝试导入时会得到以下内容：

>>> from lxml import objectify
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: DLL load failed: The specified module could not be found.
[83669 refs]

然后我在调试器中运行python，看到对LoadLibraryEx的调用失败（返回NULL）。 GetLastError（）调用返回126，这意味着它找不到dll。路径是正确的。所以我希望它找不到依赖的DLL。我在构建它的机器上运行它，因此它不是缺少的运行时库。

这是我构建dll时打印的内容：

其他一些信息：

  • 我正在使用lxml-2.3代码，因为这是我的应用程序一直使用的。
  • 我正在使用python27（32位）
    • 在Windows 7机器上运行

如果有人可以为我提供适用于Windows的lxml调试版本，或者请指出如何使用与调试dll混合的版本python dll，我会满意。

您是在Cygwin环境中构建，然后尝试在Windows中运行？尝试在Windows中构建。

答案 1 :(得分：1)

我没有尝试构建lxml的调试版本，但它几乎肯定无法工作。根据我的记忆，lxml附带的设置脚本仅用于构建发行版本。

您可以利用此功能，只需为发布版本生成调试符号（.pdb）。这个程序相当复杂，但这里有一个概述：

  1. 安装必要的构建工具（Visual Studio，Powershell）。
  2. 获取lxml依赖项的源代码（libxml2，libxslt，iconv，zlib）。
  3. 构建这些依赖项并生成其调试符号。
  4. 下载要调试的lxml版本（例如3.7.0）。
  5. 调整lxml的setup.py以指向静态构建的依赖项。
  6. 修补程序distutils使它认为必须使用您的特定Visual Studio版本，而不是用于构建Python解释器的版本。
  7. 构建lxml并生成其调试符号。
  8. 将整件物品打包成一个轮子文件。

    9. 就是这样！ :)我想链接到detailed procedure可能更合理。
