I want to call some C code from python on a linux machine. Specifically, I want to be able to run
python3 -c 'import magic; print(magic.do_add(3, 4))'
and have it give me the sum of these numbers. Here, do_add should be a C function that adds two integers.
Please give me a complete set of instructions for how to make this run, so that when I run this code as-is it will work.

Output
Certainly! I'll provide you with step-by-step instructions to create a Python module that calls a C function to add two integers. Follow these steps:
1. Create a new directory for your project:
| mkdir python_c_extension
cd python_c_extension
|
2. Create a C file named `magic.c` with the following content:
1
2
3
4

static PyObject* do_add(PyObject* self, PyObject* args) {
int a, b;
if (!PyArg_ParseTuple(args, "ii", &a, &b)) {
return NULL;
}
return PyLong_FromLong(a + b);
}
static PyMethodDef MagicMethods[] = {
{"do_add", do_add, METH_VARARGS, "Add two integers."},
{NULL, NULL, 0, NULL}
};
static struct PyModuleDef magicmodule = {
PyModuleDef_HEAD_INIT,
"magic",
NULL,
-1,
MagicMethods
};
PyMODINIT_FUNC PyInit_magic(void) {
return PyModule_Create(&magicmodule);
}
|
3. Create a file named `setup.py` with the following content:
| from distutils.core import setup, Extension
module = Extension('magic', sources=['magic.c'])
setup(name='magic',
version='1.0',
description='This is a demo package',
ext_modules=[module])
|
4. Install the Python development headers if you haven't already:
| sudo apt-get update
sudo apt-get install python3-dev
|
5. Build the extension:
6. Install the extension:
| sudo python3 setup.py install
|
7. Now you can run the command you specified:
| python3 -c 'import magic; print(magic.do_add(3, 4))'
|
This should output:
That's it! You've successfully created a Python module that calls a C function to add two integers. The `magic.do_add(3, 4)` call in Python will execute the C function `do_add` and return the result.
Note: If you're using a virtual environment, you can skip the `sudo` in step 6 and just run `python3 setup.py install`.
Also, make sure you have the necessary build tools installed on your system. On Ubuntu or Debian-based systems, you can install them with:
| sudo apt-get install build-essential
|
This process creates a shared object file (`.so` file) that Python can import as a module. The C function is compiled and linked into this shared object, allowing Python to call it directly.

Also, remember that you need to rebuild and reinstall the module if you make any changes to the C code.

Initial Query
I want to call some C code from python on a linux machine. Specifically, I want to be able to run
python3 -c 'import magic; print(magic.do_add(3, 4))'
and have it give me the sum of these numbers. Here, do_add should be a C function that adds two integers.
Please give me a complete set of instructions for how to make this run, so that when I run this code as-is it will work.

Output
Certainly! I'll provide you with step-by-step instructions to create a Python module that calls a C function to add two integers. Here's how you can set this up:
1. Create a C file named `magic.c` with the following content:
1
2
3
4
5
6
7
8
9
10
11
12

26 | #include <Python.h>
static PyObject* do_add(PyObject* self, PyObject* args) {
int a, b;
if (!PyArg_ParseTuple(args, "ii", &a, &b)) {
return NULL;
}
return Py_BuildValue("i", a + b);
}
static PyMethodDef MagicMethods[] = {
{"do_add", do_add, METH_VARARGS, "Add two integers."},
{NULL, NULL, 0, NULL}
};
static struct PyModuleDef magicmodule = {
PyModuleDef_HEAD_INIT,
"magic",
NULL,
-1,
MagicMethods
};
PyMODINIT_FUNC PyInit_magic(void) {
return PyModule_Create(&magicmodule);
}
|
2. Create a setup file named `setup.py` with the following content:
| from distutils.core import setup, Extension
module = Extension('magic', sources=['magic.c'])
setup(name='magic',
version='1.0',
description='This is a demo package',
ext_modules=[module])
|
3. Open a terminal and navigate to the directory containing both `magic.c` and `setup.py`.
4. Install the `python3-dev` package if you haven't already:
| sudo apt-get update
sudo apt-get install python3-dev
|
5. Build the module by running:
6. Install the module by running:
| sudo python3 setup.py install
|
7. Now you can run the command you specified:
| python3 -c 'import magic; print(magic.do_add(3, 4))'
|
This should output:
That's it! You've successfully created a Python module that calls a C function to add two integers. The `do_add` function in the C code takes two integer arguments, adds them, and returns the result. The Python code then imports this module and calls the `do_add` function with the arguments 3 and 4.
Remember that you'll need to have Python development headers installed on your system for this to work. The `python3-dev` package installation in step 4 should take care of this on most Linux distributions.

Query
Now please conver this answer into a JSON array that packages it all up so I don't need to think and can just copy files to specific locations and then run things. Format your answer
{"path/to/file": "contents of C file",
"path/to/python_file": "contents of any necessary python file that exposes do_add",
"build.sh": "contents of a bash file to build the project",
... # any other files necessary
}
The only thing I will do is put files in the right place and run `bash build.sh`. Do not give any explanation of the code. ONLY ANSWER WITH A SINGLE JSON OBJECT. Your answer should start
