Output
Sure, here are the steps to create a C library and call it from Python on a Linux machine:
1. Create a C source file named `magic.c` with the following content:

static PyObject *do_add(PyObject *self, PyObject *args)
{
int a, b, sum;
if (!PyArg_ParseTuple(args, "ii", &a, &b))
return NULL;
sum = a + b;
return Py_BuildValue("i", sum);
}
static PyMethodDef magic_methods[] = {
{"do_add", do_add, METH_VARARGS, "Add two integers."},
{NULL, NULL, 0, NULL}
};
static struct PyModuleDef magic_module = {
PyModuleDef_HEAD_INIT,
"magic",
"A module that adds two integers.",
-1,
magic_methods
};
PyMODINIT_FUNC PyInit_magic(void)
{
return PyModule_Create(&magic_module);
}
|
2. Save the file and navigate to the directory containing the file in a terminal.
3. Compile the C source file into a shared library using the following command:
| gcc -shared -o magic.so -fPIC -I/usr/include/python3.8 magic.c
|
Note that the `-I` flag specifies the path to the Python header files. You may need to adjust this path depending on your version of Python.
4. Create a Python script named `test.py` with the following content:
| import sys
import ctypes
lib = ctypes.cdll.LoadLibrary("./magic.so")
magic = sys.modules[__name__]
magic.do_add = lib.do_add
magic.do_add.argtypes = [ctypes.c_int, ctypes.c_int]
magic.do_add.restype = ctypes.c_int
print(magic.do_add(3, 4))
|
5. Save the file and navigate to the directory containing the file in a terminal.
6. Run the Python script using the following command:
7. If everything is set up correctly, you should see the output `7`.
8. Now, you can use the `magic` module in your Python code as follows:
| import magic
print(magic.do_add(3, 4))
|
Note that the `magic.so` file must be in the same directory as the Python script, or you will need to adjust the path in the `ctypes.cdll.LoadLibrary()` call.

|
2. Compile the C code into a shared library using the following command:
| gcc -shared -o magic.so -I /usr/include/python3.8 -fPIC magic.c
|
Note that the `-I` flag specifies the path to the Python header files, and the `-fPIC` flag generates position-independent code that can be used in a shared library.
3. Create a Python script that imports the `magic` module and calls the `do_add` function:
| import magic
print(magic.do_add(3, 4))
|
4. Run the Python script using the following command:
| python3 -c 'import magic; print(magic.do_add(3, 4))'
|
Assuming that the `magic.so` file is in the current directory or in a directory listed in the `LD_LIBRARY_PATH` environment variable, the output should be:

{

}
|
This code defines the `do_add` function that takes two integers as arguments, adds them, and returns the result as a Python object.
2. Compile the C code:
Create a new file called `setup.py` and paste the following code into it:
| from setuptools import setup, Extension
from Cython.Build import cythonize
ext_modules = [
Extension("magic", ["magic_ext.c"])
]
setup(
name="magic",
ext_modules=cythonize(ext_modules)
)
|
Now, open a terminal and navigate to the directory containing `magic_ext.c` and `setup.py`. Run the following command to build the C extension:
| python3 setup.py build_ext --inplace
|
3. Create the Python script:
Create a new file called `test_magic.py` and paste the following code into it:
| import magic
print(magic.do_add(3, 4))
|
4. Run the Python script:
In the terminal, run the following command:
| python3 -c 'import test_magic'
|
This should output `7`, which is the sum of the two integers `3` and `4`.
Alternatively, you can run the `test_magic.py` script directly with:
If you want to call the C function directly from the command line, as in your example, you can use Python's `eval()` function to import the module and call the function dynamically. However, note that using `eval()` can be dangerous and is not recommended for untrusted input. Here's the command:
| python3 -c 'import magic; print(magic.do_add(3, 4))'
|
This should also output `7`.

2. Set up the build environment.
Make sure you have the following packages installed:
- build-essential
- python3-dev
For Ubuntu, you can install them using the following command:
| sudo apt-get install build-essential python3-dev
|
3. Create a `setup.py` file.
Create a new file named `setup.py` with the following content:
| from setuptools import setup, Extension
setup(
name='magic_ext',
version='0.1',
ext_modules=[
Extension('magic_ext', ['magic_ext.c'])
],
)
|
4. Build the C extension.
Run the following command to build the extension:
| python3 setup.py build_ext --inplace
|
This command will create a new file named `_magic_ext.cpython-3xm-x86_64-linux-gnu.so` in the current directory (assuming you're using a 64-bit Linux system).
5. Write the Python script.
Create a new file named `test.py` and add the following code:
| import sys
import _magic_ext
print(_magic_ext.do_add(3, 4))
|
6. Run the Python script.
You can now run the Python script using the following command:
This should output:
7. If you want to use the `import magic` syntax instead of `import _magic_ext`, you can create a `magic.py` wrapper file:
Create a new file named `magic.py` and add the following code:
Now, you can use the following command to run the script with the `import magic` syntax:
| python3 -c 'import magic; print(magic.do_add(3, 4))'
|
This should also output:

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
.
