Back to README

Via Nix

With Nix flakes enabled:

git clone https://github.com/trailofbits/mewt.git
cd mewt
nix develop --command bash -c 'just install-nix' # or 'direnv allow' then 'just build'
mewt --version

Native toolchain

Requirements (Linux/macOS):

• Rust toolchain (via rustup)
• C toolchain (gcc/clang) and make
• pkg-config
• SQLite development headers (libsqlite3-dev/sqlite)

Windows is currently unsupported.

Install common prerequisites:

macOS (Homebrew)

# Command Line Tools (if not already installed)
xcode-select --install || true

brew install rustup-init sqlite pkg-config
rustup-init -y
source "$HOME/.cargo/env"

Ubuntu/Debian

sudo apt update
sudo apt install -y build-essential pkg-config libsqlite3-dev curl
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
source "$HOME/.cargo/env"

Build and run

cargo build --release
./target/release/mewt --help

Optional (install into your cargo bin):

cargo install --path . --locked --force
mewt --version
