Getting Started

Grok16 5.2.0 ships a unified g16 driver. One binary compiles C and C++; backends live in libexec/grok16/. g++16 is a compat symlink.

Requirements

Linux x86_64
Host gcc/g++, git, cmake, Python 3 / GPY-16
GCC build deps (gmp, mpfr, mpc, flex, bison)
~6 GB disk for vendor/, build/, prefix

Bootstrap

git clone https://github.com/ZacharyGeurts/Grok16.git
cd Grok16
git checkout v5.2.0
export G16_PREFIX="$(pwd)"

./scripts/grok16-toolchain.sh bootstrap
./scripts/grok16-toolchain.sh rebuild
./scripts/grok16-toolchain.sh verify

Rebuild modes

Mode	Env	Use when
Fast (default)	`G16_FAST_REBUILD=1`	Day-to-day iteration
Full	`G16_FULL_REBUILD=1`	distclean + 3-stage bootstrap
Release	`G16_RELEASE_PROFILE=1`	Production prefix — LTO + PGO + field_opt

./scripts/grok16-toolchain.sh rebuild
G16_RELEASE_PROFILE=1 ./scripts/grok16-toolchain.sh rebuild

Verify & gate

./scripts/grok16-toolchain.sh verify
./scripts/grok16-toolchain.sh test-battery-expert
./scripts/grok16-toolchain.sh test-battery-release
./scripts/grok16-toolchain.sh test-battery-belt
