Pre-built binaries for the airgap-cpp-devkit suite. 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-cpp-devkit

This submodule contains prebuilt archives that allow developers on air-gapped systems to skip source compilation entirely. Each module in the main repo has a corresponding entry here.

In binary-restricted environments (where prebuilt binaries are not permitted by policy), this submodule can be skipped entirely -- every tool in the main repo can also be built from vendored source.

CMake 4.3.1 prebuilt binaries. Both files are under 49MB -- no split required.

7-Zip 26.00 prebuilt binaries for Windows and Linux. All files under 49MB.

Servy 7.8 Windows service manager. Single file under 100MB -- no split required.

Conan 2.27.0 self-contained executables. Both files under 49MB -- no split required.

gRPC v1.78.1 prebuilt for Windows x64 (MSVC 19.50, Release). Full cmake --target install output: bin/, include/, lib/, share/.

Install via frameworks/grpc/install-prebuilt.ps1.

.NET SDK 10.0.201 for Windows and Linux.

Python 3.14.4 portable interpreters.

llvm-mingw 20260324 -- LLVM-based MinGW-w64 toolchain.

Clang 20.1.8 RPM packages for RHEL 8.

Prebuilt clang-format, clang-tidy, and Ninja binaries.

GCC Toolset 15 RPM packages for RHEL 8.

WinLibs GCC 15.2.0 + MinGW-w64 13.0.0 UCRT toolchain for Windows.

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.

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.

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.

This submodule is initialized as part of the main repo setup:

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

Each tool's install script references this submodule automatically.

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

git clone https://github.com/NimaShafie/airgap-cpp-devkit
cd airgap-cpp-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.
