llama.cpp - Termux (Snapdragon)

Upstream llama.cpp, built for Android Termux (arm64) with bundled .so, tuned for Qualcomm Snapdragon devices.

Prebuilt llama.cpp binaries for Android Termux (arm64) with bundled shared libraries for maximum CPU performance on Snapdragon.

What This Is

• Prebuilt llama.cpp binaries for Termux on Android (arm64).
• Optimized build profile intended for Qualcomm Snapdragon devices.
• This is intended as the "safe default" profile (no Pixel/Tensor-specific assumptions).

Exact upstream commit + build flags for this specific release are recorded in docs/build_meta.txt.

This is intended as the "safe default" build (DOTPROD-first; no Pixel/Tensor-specific assumptions).

Commands (No Clobbering Termux PKG)

This package intentionally installs namespaced commands so you can keep the Termux package llama-cpp installed for benchmarks:

• llama-cli-snapdragon
• llama-bench-snapdragon
• llama-server-snapdragon

Installation

pkg update && pkg upgrade -y
pkg install -y nodejs-lts openssl
npm install -g @mmmbuto/llama-cpp-termux-snapdragon

Automatic Runtime Deps (postinstall)

On Termux, the npm postinstall step will attempt to install missing runtime packages automatically via pkg:

• openssl (for libssl.so.3 / libcrypto.so.3)
• libc++ (for libc++_shared.so)

To skip (CI/dry runs):

export LLAMA_CPP_TERMUX_SKIP_PKG_INSTALL=1

Verify

llama-cli-snapdragon --version
llama-bench-snapdragon -h

Benchmarks

This package is designed to be installed alongside the Termux llama-cpp package so you can compare:

• Termux PKG: llama-bench
• Snapdragon build: llama-bench-snapdragon

Build (Repro)

Packaging Details (.so)

This package bundles these libraries under lib/:

• libggml*.so*, libllama*.so*, libmtmd*.so*

The wrappers in bin/ set LD_LIBRARY_PATH so the binaries use the packaged .so.
