[CPP] Embedding Python and use GDB

[Razazel]

Hi, I'm using Python 3.6 in a C ++ application. (Mingw 5.3 and GDB 7.10.1).
main.cpp :

#include <include/Python.h>

int main(int argc, char *argv[])
{
    wchar_t *program = Py_DecodeLocale(argv[0], NULL);
    if (program == NULL) {
        fprintf(stderr, "Fatal error: cannot decode argv[0]\n");
        exit(1);
    }
    Py_SetProgramName(program);  //optional but recommended
    Py_Initialize();
    PyRun_SimpleString("from time import time,ctime\n"
                       "print('Today is', ctime(time()))\n");
    if (Py_FinalizeEx() < 0) {
        exit(120);
    }
    PyMem_RawFree(program);
    return 0;
}

project.pro :

LIBS += "D:\Python 3.6.3\libs\libpython36.a"INCLUDEPATH += "D:\\Python 3.6.3\\"DEPENDPATH += "D:\\Python 3.6.3\\"
QMAKE_CXXFLAGS += -D_hypot=hypot

This code works perfectly in release.

My problem is with Debug launch (with GDB).

Error:
Fatal Python error: Py_Initialize: unable to load the file system codec
ModuleNotFoundError: No module named 'encodings'

Current thread 0x00002f24 (most recent call first):
Fatal Python error: 
Py_Initialize: unable to load the file system codec

Thank you

This is an old article, (2011), but the concepts probably haven't changed too much.

Probably of little use, but maybe not.
I used gdb with embedded C, and still remember that setup was a pain.
And running as well, since Rom variables must be created at run time.

Under linux, with g ++ 4.6 and GDB 7.12.50.
I can debug C ++ code that uses Python3.6m without errors.
I deploy the Windows version later.

I also found this, which looks a bit more promising:

Thank you for you answers.

I test that tomorrow.
