I am trying to install SoundAnalyse. I got the following error information:

It seems like the error comes from installing analyseffi.

I just find the problem:
The code work fine in Python 2.x, but Py_InitModule is no longer used in Python 3.x.

If you are using Python 3.x. During analyseffi.c
use the following code:

// PyMODINIT_FUNC 
// initanalyseffi(void)
// {
//     (void) Py_InitModule("analyseffi", methods);
// }

/* The following new code for compatible with Python  3
   Added by Luwei Yang 20 May 2017 */
static struct PyModuleDef analyseffi = 
{
    PyModuleDef_HEAD_INIT,
    "analyseffi", /* name of module */
    "",          /* module documentation, may be NULL */
    -1,          /* size of per-interpreter state of the module, or -1 if the module keeps state in global variables. */
    methods
};

PyMODINIT_FUNC PyInit_analyseffi(void)
{
    return PyModule_Create(&analyseffi);
}

After modifying analyseffi.c, how to install SoundAnalyse？
Could you please tell me how to install this？
I tried to use "python setup.py install", but it is still cannot be imported.
Thank you.
