Demo of compiling a small C dynamic library in a Python script and directly loading it with ctypes.
import ctypes
import tempfile
import distutils.ccompiler
from pathlib import Path
from random import randint
int roll(void) {{
return {randint(1, 6)};
def compile_link_and_load(source_code):
with tempfile.TemporaryDirectory() as tempdir_name:
tempdir = Path(tempdir_name)
source_file = tempdir / 'fairdice.c'
source_file.write_text(source_code, encoding='UTF-8')
cc = distutils.ccompiler.new_compiler()
object_files = cc.compile([str(source_file)], tempdir_name, extra_preargs=['-fPIC'])
cc.link_shared_lib(object_files, tempdir / 'fairdice')
return ctypes.CDLL(tempdir / '')
def main():
libfairdice = compile_link_and_load(SOURCE_CODE)
