C ++ encapsulate the python extension module ImportError

Compile the extension module (Dynamic Link Library) for Python using C ++ and call the extension function developed by C ++ in Python. the following error occurs, is it annoying:
Traceback (most recent calllast ):

File "t. py", line 6, in <module>

Import Rabbit

ImportError: No modulenamed Rabbit

Possible causes include:

1. If Python2.5 is used during development, check whether the generated dynamic library extension is "pyd". (If the suffix is dll, modify it );

2. In the source code of DLLMAIN, export the initialization code of the extension module:

# Ifdef PYRABBIT_EXPORTS

# Define PYRABBIT_API _ declspec (dllexport)

# Else

# DefinePYRABBIT _ declspec (dllimport)

# Endif

Extern "C" PYRABBIT_API void initRabbit (){

PyObject * m = Py_InitModule ("Rabbit", RabbitMethods );

}

3. The generated dynamic library file (suffixed with pyd) is not included in the environment variable. You can run the following command on the console to check the file;

Import OS

OS. sys. path
