airgap-devkit-prebuilt

Author: Nima Shafie

Prebuilt binary archives for the airgap-devkit ecosystem. All binaries are precompiled, integrity-verified, and ready for air-gapped installation -- no compiler, no internet access, no package manager required.

Main repo: https://github.com/NimaShafie/airgap-devkit

---

Purpose

This repository is an optional submodule of airgap-devkit. Tools that declare "uses_prebuilt": true in their devkit.json will look for their binary archives here under the same relative path (e.g. prebuilt-binaries/toolchains/clang/mingw/).

Tools without uses_prebuilt: true are built from vendored source and do not require this submodule at all. In binary-restricted environments the entire submodule can be skipped -- every tool has a source-build path.

Adding this submodule to your clone

git submodule add https://github.com/NimaShafie/airgap-devkit-prebuilt prebuilt-binaries/

Or if cloning the main repo from scratch:

git clone https://github.com/NimaShafie/airgap-devkit
cd airgap-devkit
git submodule update --init prebuilt-binaries

Archive Formats

Windows binaries use .zip (deflate level 9) -- extractable with PowerShell Expand-Archive, unzip, or any standard zip tool. No 7-Zip required.

Linux binaries use .tar.gz or .tar.xz -- extractable with standard tar.

The only .7z files present are the 7-Zip extras package and Servy, both of which are either self-bootstrapping or require 7-Zip as a prerequisite by design.

---

Split Parts

Large archives are split into parts named <archive>.part-aa, part-ab, etc. Reassemble before extraction:

# Linux
cat archive.zip.part-* > archive.zip

# Windows (Git Bash)
cat archive.zip.part-* > archive.zip

# Windows (PowerShell)
$parts = Get-ChildItem -Filter "archive.zip.part-*" | Sort-Object Name
$out = [System.IO.File]::OpenWrite("archive.zip")
foreach ($p in $parts) {
    $bytes = [System.IO.File]::ReadAllBytes($p.FullName)
    $out.Write($bytes, 0, $bytes.Length)
}
$out.Close()

Install scripts handle reassembly automatically -- no manual steps required.

---

Integrity

Each module directory contains a manifest.json with SHA256 hashes for all parts and reassembled archives. Install scripts verify integrity before extraction. Nothing is extracted if verification fails.

Skipping This Submodule

In binary-restricted environments, do not initialize this submodule:

git clone https://github.com/NimaShafie/airgap-devkit
cd airgap-devkit
# Do NOT run: git submodule update --init prebuilt-binaries
# Build all tools from vendored source instead

Every tool in the main repo has a source-build path that does not require this submodule.
