[SciPy-User] [SciPy-user] Weave Inline with MSVC

[SamehK]

By checking the generated cpp file, I was wondering if there's a bug
somewhere that causes weave to dump "__attribute__" and "unused" when they
haven't been defined.

The cpp file:
static PyObject* compiled_func(PyObject*self, PyObject* args)
{
    py::object return_val;
    int exception_occured = 0;
    PyObject *py__locals = NULL;
    PyObject *py__globals = NULL;
    if(!PyArg_ParseTuple(args,"OO:compiled_func",&py__locals,&py__globals))
        return NULL;
    try                              
    {                                
        PyObject* raw_locals __attribute__ ((unused));
        raw_locals = py_to_raw_dict(py__locals,"_locals");
        PyObject* raw_globals __attribute__ ((unused));
        raw_globals = py_to_raw_dict(py__globals,"_globals");
        /* argument conversion code */     
        /* inline code */                   
        /* NDARRAY API VERSION 1000009 */
        int i;    /*I would like to fill in changed    locals and globals
here...*/   
    
    }                                       
    catch(...)                        
    {                                 
        return_val =  py::object();   
        exception_occured = 1;        
    }                                 
    /* cleanup code */                   
    if(!(PyObject*)return_val && !exception_occured)
    {
                                  
        return_val = Py_None;            
    }
                                  
    return return_val.disown();          
}
