#include<Python.h>: Error in included file

Factao

I want to run an embedded python script on Qt, but my compiler seem to find a lot of error inside Python.h (more specifically, inside Pyobject.h and sliceobject.h. It might be something called slots, which appeared to be flagged as the Qt slots or it might be a bunch of missing semicolon or parenthesis.

Since these files are from the official python distribution and the include files of the pythonXX.lib library, I would rather not modify them, since this is supposed to be functional.

Would there be a way to prevent my compiler from flagging error within these files?

@Factao If the problem is the conflict between Python "slots" and Qt "slots" you can set QT_NO_KEYWORDS (see https://github.com/pytorch/pytorch/issues/19405)

@jsulm Thank you!

I am also getting a lot of syntax error in this line:

PyAPI_FUNC(int) PySlice_GetIndices(PyObject *r, Py_ssize_t length, Py_ssize_t *start,
                                   Py_ssize_t *stop, Py_ssize_t *step);
Py_DEPRECATED(3.7)
PyAPI_FUNC(int) PySlice_GetIndicesEx(PyObject *r, Py_ssize_t length,
                                     Py_ssize_t *start, Py_ssize_t *stop,
                                     Py_ssize_t *step,
                                     Py_ssize_t *slicelength);

These are the line 43 to 49 of sliceobject.h. There apparently is a lot of missing parenthesis and semicolon before a 'constant', but there isn't any apparent conflicting keyword.

@Factao
Since there is nothing wrong in the C++ PySlice_... declarations, I would assume the macros (PyAPI_FUNC(), Py_DEPRECATED()) are not defined when it hits these lines, for whatever reason....

Factao

@JonB They seem defined for me. Here is what it look like and what their definition seem to be. alt text

@Factao
Those may only be "errors/warnings" coming from the IDE's code completion plugin, which can get things wrong. Do you get those errors when you actually compile?

Factao

@JonB My apologies, I can't read. Here are the definition. I am also getting a 'not throw' on PySlice_GetIndices and PySlice_GetIndicesEx, with a message that my beginner brain cannot process.

@JonB I'm a little bit rusted in C++ (I do not remember if compiling and building are the same), but I am getting these error when I am building. I havent really done more.
