Python 3.14.0 Free-Threading for Termux ARM64

Python 3.14.0 Free-Threading for Termux ARM64

Update (2025-10-24): Package updated with fixes from real Termux testing.

What's Fixed

✅ install.sh improvements:

• Automatically configures ~/.bashrc with PATH and LD_LIBRARY_PATH
• Interactive prompt for configuration
• Forces installation to ~/.local to avoid system conflicts
• Only installs python3.14t binary (no symlink overwrites)

✅ README simplification:

• Clearer installation steps
• Better verification instructions
• Removed verbose content (available in main repo)

Installation

Download and install:

wget https://github.com/Fibogacci/python314t-for-termux/releases/download/v3.14.0/termux-python314t-3.14.0.tar.gz
tar -xzf termux-python314t-3.14.0.tar.gz
cd termux-python314t-3.14.0
bash install.sh
source ~/.bashrc

Verify:

python3.14t --version
python3.14t -c "import sys; print(f'GIL: {sys._is_gil_enabled()}')"

Expected: GIL: False ✅

• Platform: Android 7.0+ (API 24+)
• Build: Cross-compiled from Linux x86_64
• Compiler: Clang 18.0.4 (Android NDK 27.3.13750724)
• Package size: 21MB compressed, 67MB uncompressed

Package Contents

• python3.14t executable (6.9KB)
• libpython3.14t.so shared library (31MB)
• Python 3.14t standard library (34MB, optimized)
• C headers for extension development (2.6MB)

Performance

• Multi-threaded CPU-bound tasks: 1.5-2.5x speedup on 4-core devices
• Single-threaded overhead: ~5-10% (expected for free-threading)

Known Limitations

• pip not included by default (install via get-pip.py)
• Some C extensions may need recompilation for free-threading
• GUI modules removed (tkinter, idlelib)
• Test suite removed for size optimization
