I'm having trouble importing Python.h to a C program. I have 4 files, hellofunc.c, hellomake.c, hellomake.h and Makefile. The hellomake.h, Python.h and all related Python files are in a include folder. And the rest is in the program folder.

├───include
│   ├───cpython
│   └───internal
├───lib
└───program

The code of hellofunc.c file is:

#include <stdio.h>
#include <hellomake.h>

void myPrintHelloMake(void) {

  printf("Hello makefiles!\n");

  return;
}

The code of hellomake.h is:

void myPrintHelloMake(void);

The code of hellomake.c is:

#include <conio.h>
#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
#include <windows.h>
#include <Python.h>
#include <hellomake.h>

int main() {
  // call a function in another file
  myPrintHelloMake();

  Py_Initialize();
    PyRun_SimpleString("print('Hello World from Embedded Python!!!')");
    Py_Finalize();

  return(0);
}

The code of Makefile is:

IDIR =../include
CC=gcc
CFLAGS=-I$(IDIR)

ODIR=obj
LDIR =../lib

LIBS=-lm

_DEPS = hellomake.h
DEPS = $(patsubst %,$(IDIR)/%,$(_DEPS))

_OBJ = hellomake.o hellofunc.o 
OBJ = $(patsubst %,$(ODIR)/%,$(_OBJ))


$(ODIR)/%.o: %.c $(DEPS)
    $(CC) -c -o $@ $< $(CFLAGS) 

hellomake: $(_OBJ)
    $(CC) -o $@ $^ $(CFLAGS) $(LIBS)

.PHONY: clean

clean:
    rm -f *.o *~ core $(INCDIR)/*~

The error that I got is:

gcc -o hellomake hellomake.o hellofunc.o -I../include -lm
hellomake.o:hellomake.c:(.text+0x14): undefined reference to `_imp__Py_Initialize'
hellomake.o:hellomake.c:(.text+0x2a): undefined reference to `_imp__PyRun_SimpleStringFlags'
hellomake.o:hellomake.c:(.text+0x31): undefined reference to `_imp__Py_Finalize'
collect2.exe: error: ld returned 1 exit status
