C++ Swig Python（C 中的嵌入式 Python）在发布中有效，但在调试中无效

我选择了Python＆amp; Swig 绑定作为应用程序的脚本环境。

作为原型，使用 main() 创建了一个简单的 VS 解决方案，该解决方案初始化 Python（Py_Initalize、Py_setPyHome 等）&执行test.py。在同一个解决方案中创建了另一个项目，它是一个简单类的 DLL。使用 SWIG 来包装此类。该 DLL 是 _MyClasses.pyd。 test.py 创建我的类的对象 &调用其成员函数。

所有这些在发布模式下都非常有效。但在调试模式下不起作用（甚至尝试用头敲笔记本电脑;-)）。

我的工作输出如下所示（在发布和调试中）：

  x64
    -debug
     - _MyClasses.pyd
     - MyClasses.py
     - test.exe
     - test.py
     - python26.dll
     - python26_d.dll

请注意，调试版本与 python26_d.lib 链接。为此必须自己构建 python！

test.py
import MyClasses

print "ello"
m = MyClasses.Male("John Doe", 25)
print m.getType()

Male是C++类。

The problem:
Traceback (most recent call last):
  File "test.py", line 6, in <module>
    import MyClasses
  File "...\x64\Debug\MyClasses.py", line 25, in <module>
    _MyClasses = swig_import_helper()
  File "...\x64\Debug\MyClasses.py", line 17, in swig_imp
ort_helper
    import _MyClasses
ImportError: No module named _MyClasses
[15454 refs]

我习惯了 Makefiles &我是 Visual Studio 新手。我不知道罪魁祸首是谁：Swig、Python 的调试版本、Visual Studio，我的愚蠢。

先感谢您。这将是一个很大的帮助。

Platform: Windows 7, 64 bit (x64), Visual Studio 2008

I chose Python & Swig binding as the scripting environment of the application.

As a prototype, created a simple VS solution with main() which initializes Python (Py_Initalize, Py_setPyHome, etc) & executes test.py. In the same solution created another project which is a DLL of a simple class. Used SWIG to wrap this class. This DLL is the _MyClasses.pyd. test.py creates the objects of my class & calls its member functions.

All this works like a charm in the Release mode. But does not work in Debug mode (even tried banging my head on the laptop ;-) ).

Output of my work looks like this (in both release & debug):

  x64
    -debug
     - _MyClasses.pyd
     - MyClasses.py
     - test.exe
     - test.py
     - python26.dll
     - python26_d.dll

Note that the debug version is linked against python26_d.lib. Had to build python myself for this!

test.py
import MyClasses

print "ello"
m = MyClasses.Male("John Doe", 25)
print m.getType()

Male is the C++ class.

The problem:
Traceback (most recent call last):
  File "test.py", line 6, in <module>
    import MyClasses
  File "...\x64\Debug\MyClasses.py", line 25, in <module>
    _MyClasses = swig_import_helper()
  File "...\x64\Debug\MyClasses.py", line 17, in swig_imp
ort_helper
    import _MyClasses
ImportError: No module named _MyClasses
[15454 refs]

I am used to Makefiles & am new to Visual Studio. I dont know who the culprit is here: Swig, The debug build of Python, Visual Studio, my stupidity.

Thank you in advance. It will be a great help.
