我正在尝试调试我在多线程 qt webkit 应用程序中遇到的段错误。我安装 python-dbg 是为了在 gdb 中给我漂亮的打印，并在启动时收到以下错误

python2.7-dbg node.py
Traceback (most recent call last):
  File "node.py", line 4, in <module>
    import msgpack
  File "/usr/lib/pymodules/python2.7/msgpack/__init__.py", line 3, in <module>

ImportError: /usr/lib/pymodules/python2.7/msgpack/_msgpack.so: undefined symbol: Py_InitModule4
Error in sys.excepthook:

    import apt_pkg
ImportError: /usr/lib/python2.7/dist-packages/apt_pkg.so: undefined symbol: Py_InitModule4

Original exception was:
Traceback (most recent call last):
  File "node.py", line 4, in <module>
    import msgpack
  File "/usr/lib/pymodules/python2.7/msgpack/__init__.py", line 3, in <module>
    from msgpack._msgpack import *
ImportError: /usr/lib/pymodules/python2.7/msgpack/_msgpack.so: undefined symbol: Py_InitModule4

当我运行不使用 msgpack 的脚本版本时，我得到了同样的结果......

在这两种情况下，它的外观 Py_InitModule4...python 专家有什么想法吗？使用普通 python 2.7 代码运行良好（除了段错误很晚）

如果有一种更简单的方法可以在 gdb 中进行漂亮的打印，我也愿意接受。基本上只是在寻找一个 python 风格的堆栈跟踪

经过一番戳，过去的 ubuntu python-dbg 库中似乎存在与此相关的错误。我在诉讼中提出了一个错误，发现我只是没有阅读文档。需要安装 -dbg 版本的库（本例中为 MySQLdb 和 PyQT4）

没有消息包的版本，所以我发布了另一个关于如何做到这一点的问题

这是标记为无效的错误报告以供参考https://bugs.launchpad.net/ubuntu/+source/python2.7/+bug/1040914
