# Python Wrapper Build Fixes

## Problem

The Python wrapper generation fails during build with errors:

1. `AttributeError: 'NoneType' object has no attribute 'split'` in metadoc.py
2. Exceptions about missing `maybenil`/`notnil` annotations in abstractapi.py

## Solution

### metadoc.py

Added null check for `parametername` node text to prevent NoneType errors.

### abstractapi.py

Changed hard exceptions to warnings for missing pointer annotations (`maybenil`/`notnil`). The code now defaults to `maybenil=True` when annotation is missing.

## Apply Patches

```bash
cd external/linphone-sdk
patch -p1 < ../../fixes/python-wrapper-build-fix/metadoc.patch
patch -p1 < ../../fixes/python-wrapper-build-fix/abstractapi.patch
```
