I need wrap a project into Python. All C++ classes are built as a shared
library libGORGON.so. The boost.python wrapper file is built as
libpyGORGON.so. But when I try to import libpyGORGON in Python prompt. I got
error:
Python 2.4.4 (#1, Oct 23 2006, 13:58:18) [GCC 4.1.1 20061011 (Red Hat
4.1.1-30)] on linux2 Type "help", "copyright", "credits" or "license" for
more information.
>>> import libpyGORGON.so

> c++filt _ZTIN8wustl_mm13Visualization8RendererE
typeinfo for wustl_mm::Visualization::Renderer
so this one is missing.
when you say you have _ZTIN8wustl_mm13Visualization8RendererE (by using nm
to check), what symbol does it have? You sure it's not U?
PS how did your last question go? care to update?

噢，nm的结果果然是U：
U _ZTIN8wustl_mm13Visualization8RendererE
U的意思是“This symbol is undefined”。到底是怎么回事呢？
如果我用nm libGORGON.so | grep blahblah
就会什么也不返回，返回U是指有declaration，没有definition吗？
非常感谢你,thrust，最近我的很多问题都能从你那里得到答案。

问题解决了，Renderer是一个base class，定义了一个virtual destructor，
virtual ~Renderer();
但是没有define。改成：
virtual ~Renderer() {}
就可以了。
再次向thrust表示感谢。
