我正在调试另一个由使用 lxml 的脚本导入的 dll。我需要从 lxml 项目创建一个 objectify_d.pyd 和 etree_d.pyd。我按照此处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

我试着做：

python setup.py build --debug

但这没有用。

构建似乎成功。一个 objectify_d.pyd 和 etree_d.pyd 被创建。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，我在尝试导入时得到以下信息：

>>> 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 并看到对 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。所以我希望它没有找到依赖的DLL。我在构建它的机器上运行它，所以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在使用的。
  • 我正在使用 python27（32 位）的 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，或者向我说明如何使用与调试 dll 混合的发布 python dll，我会很满意。

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

我还没有尝试构建 lxml 的调试版本，但几乎可以肯定它不会工作。据我记得，lxml 附带的设置脚本仅用于构建发布版本。

您可以利用这一点，简单地为发布版本生成调试符号 (.pdb)。该过程相当复杂，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的依赖（libxml2、libxslt、iconv、zlib）的源代码。
  3. 构建这些依赖项并生成它们的调试符号。
  4. 下载您要调试的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 distutils 使其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. 将整个东西打包在一个轮子文件中。

而已！:) 我想链接到详细程序可能更合理。
