absl-py not working with Cython

Hi, I want to compile my python app using absl-py into executable using Cython.

I tried it with just the example

from absl import app
from absl import flags

FLAGS = flags.FLAGS
flags.DEFINE_string("name", "David", "Your name.")
flags.DEFINE_integer("num_times", 1, "Number of times to print greeting.")

def main(argv):
del argv # Unused.

if __name__ == "__main__":
app.run(main)

I am compiling it using cython as **cython app.py --embed** (to make it executable)

After this app.c is generated, i am using gcc to compile it as

**gcc -Os $(pkg-config --cflags python3) app.c -lpython3.8 -o app**

which workes without any error.

however when i try to execute it, this is an error that i get :

Traceback (most recent call last):
File "app.py", line 5, in init app
flags.DEFINE_string("name", "David", "Your name.")

globals_for_frame = sys._getframe(depth).f_globals # pylint: disable=protected-access
ValueError: call stack is not deep enough

The error occurs in absl/flags/_helpers.py at get_calling_module_object_and_name when the call stack depth is insufficient during Cython compilation. Examine how absl-py introspects the stack and how Cython's --embed changes module loading. Start by reproducing the issue with the provided example, then look at sys._getframe usage in the helpers module. Determine if the module detection logic needs adjustment for embedded executables.
