C++ Swig Python (Embedded Python in C++) works in Release but not in Debug
- by sambha
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

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.
