GDB build

Reproducible native builds of GNU GDB for Linux, macOS, and Windows. The result is a relocatable archive suitable for embedding in another application.

The source version and SHA-256 are pinned in versions.env. Builds deliberately disable Python, Guile, source-highlight, and code signing to keep the runtime small and deterministic. Signing and notarization belong in the downstream product pipeline.

Outputs

Each build produces artifacts/gdb_<platform>_<version>.zip. Archives have the same layout on every host:

gdb/
  COPYING
  bin/gdb[.exe]
  lib/                 # non-system runtime libraries, when needed
  share/gdb/
  build-manifest.json

Supported platform names are linux, linux-arm, macosx, and win64. The macOS archive contains a universal ARM64/x86_64 executable and universal GMP/MPFR libraries. Building it requires an Apple Silicon worker with Rosetta. The ARM64 slice is remote-only: upstream GDB lacks a Darwin ARM64 native backend. The x86_64 slice retains Darwin native support. Both support all remote targets. The version-scoped patch in patches/ adds the missing declaration include required to compile GDB 17.2's Darwin native source.

Local builds

Linux and macOS:

./scripts/build-posix.sh linux    # or linux-arm / macosx

The POSIX build expects a C/C++ toolchain, GNU make, Python 3, xz, and the GDB development dependencies (GMP, MPFR, expat, readline, xz, and zstd). Packaging uses patchelf on Linux and the Xcode command-line tools on macOS.

Windows builds run in MSYS2's MINGW64 environment:

./scripts/build-windows.ps1

The PowerShell entry point locates an existing MSYS2 installation or bootstraps a pinned, SHA-256-verified portable MSYS2 environment in the workspace. It then installs the required MinGW packages with pacman and invokes the shared build logic. It does not require or perform code signing.

Jenkins

Jenkinsfile defines a parameterized matrix build. Configure a Pipeline from SCM pointing at this repository and leave the script path as Jenkinsfile. The job only checks out this public repository, builds on the selected native workers, verifies the resulting executable with --version and a short MI2 smoke test, and archives the platform zip.

GDB itself is licensed under GPLv3; each archive includes GDB's COPYING file. The build orchestration in this repository is MIT licensed.
