通过 QuantLib-SWIG 进行 Python 绑定 [英] Python binding through QuantLib-SWIG

问题描述

我一直在尝试让 QuantLib 的 Python 绑定工作一段时间，但到目前为止没有任何成功.

I have been trying to get Python binding for QuantLib working for a while now but without any success so far.

我确实遵循了 QuantLib 安装指南和 wiki.那就是使用 VC9 而不是 VC10 来构建 QuantLib，这对我来说很好用.

I did follow QuantLib installation guidelines and wiki. That is to build QuantLib using VC9 and not VC10 which works fine for me.

当我尝试构建 Python 安装文件时，我被告知 MSVC 无法检测到 QuantLib 安装.

When I try to build Python setup file, I am being told that MSVC cannot detect QuantLib installation.

请有人能告诉我我在这里遗漏了什么.正如您现在已经意识到的那样，我是一个初学者，如果过去曾反复问过问题，我深表歉意，但我在不同的论坛中找不到我的问题的任何答案:wilmott、sourceforge、stack溢出，量化交易.

Please could someone be kind enough to advise what I am missing here. As you would have realized by now, I am much of a beginner with this and apologize if question has been asked over and over in the past but I couldn't find any answer to my question in the different forums: wilmott, sourceforge, stack overflow,quant exchange.

任何帮助将不胜感激.

最好的问候

推荐答案

设置环境变量的时候把 = 号周围的空格去掉，否则 Python 找不到.以下是我还在办公室的 WinXP 机器上发生的情况:

Remove the spaces around the = sign when you set the environment variables, or Python won't find them. Here is what happens on a WinXP box I still have around at the office:

C:\Documents and Settings\lballabio>set FOO=foo

C:\Documents and Settings\lballabio>set BAR = bar

C:\Documents and Settings\lballabio>python
Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.environ['FOO']
'foo'
>>> os.environ['BAR']
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\os.py", line 423, in __getitem__
    return self.data[key.upper()]
KeyError: 'BAR'
>>>

FOO(无空格设置)被找到；BAR(带)不是.

FOO (set without spaces) is found; BAR (with) is not.

未找到 QL_DIR、INCLUDE 或 LIB 变量会导致其他级联错误.

Not finding the QL_DIR, INCLUDE or LIB variables causes the other errors in cascade.
