I have been working previously on Buildroot support for [Swift on Armv5](https://forums.swift.org/t/linux-armv5-support/56278) since Swift 5.4, and I'm excited to share that work has culminated into a set of scripts and distributable binaries to cross compile the Swift runtime (and SwiftPM packages) for Debian 11 Armhf. This binary distribution can be used with existing toolchains from [Swift.org](http://Swift.org) and @futurejones [swiftlang.xyz](https://forums.swift.org/t/new-swift-package-repository-for-ubuntu-debian-linux-distributions/50412). > **[GitHub - colemancda/swift-armv7: Swift runtime for Linux Armv7](https://github.com/colemancda/swift-armv7)** > > Swift runtime for Linux Armv7. Contribute to colemancda/swift-armv7 development by creating an account on GitHub. I have also provided [Docker images](https://hub.docker.com/repository/docker/colemancda/swift-armv7) to quickly cross compile for Debian 11 Armhf - [latest](https://hub.docker.com/layers/218600481/colemancda/swift-armv7/latest/images/sha256-4f69dcbba773487c9707d90b42add293ce58aa97c482add77ea5cfc710b58d98?context=repo): this is the bare minimum environment needed to cross compile the Swift runtime for Armv7. Includes Swift 5.6.1 compiler, Cmake 3.22 and LLVM headers. The `build.sh` script can be used to cross compile the runtime. Takes about 5 minutes to compile Swift, Dispatch, Foundation and XCTest. - [5.6.1-prebuilt](https://hub.docker.com/layers/222220293/colemancda/swift-armv7/5.6.1-prebuilt/images/sha256-12dfb17f0dfd6376f6bd5637ae30c6bdb74370f53fb5e887705cb6d009e7b811?context=repo): This image builds on `latest` as a base, but also includes the Debian 11 sysroot needed to cross compile Swift packages and the Swift runtime already compiled for Armv7. The `generate-swiftpm-toolchain.sh` and `build-swift-package.sh` scripts can be used to cross compile packages. Example of Docker image usage: > In this example, the `colemancda/swift-armv7:5.6.1-prebuilt` Docker image is used to cross compile the package in a x86 CI environment. The `-prebuilt` suffix means the image contains the Debian 11 Armhf sysroot with the Swift runtime librares. The next GitHub Action takes the compiled `.xctest` executable and runs it in a self hosted Armv7 environment (Orange Pi Zero 2 development board). v0.3.0 binaries - [Swift 5.6.1 runtime](https://github.com/colemancda/swift-armv7/releases/download/0.3.0/swift-armv7.tar.gz) with Dispatch, Foundation and XCTest cross compiled for Debian 11 Armhf - [Debian 11 Armhf sysroot](https://github.com/colemancda/swift-armv7/releases/download/0.3.0/bullseye-armv7.tar.gz) ---

Great work! I am not super familiar with similarities between Debian and OpenWRT, but I see you have mentioned OpenWRT before. Have you been to compile any Swift application for OpenWRT and if so, can you give some direction on how I can achieve this, possibly using your prebuilt docker images. ---

Ok, after a lot of trial and error, I seem to have got it working by creating a new buildroot package for the target platform I am building for and updating a lot of library and include paths. Some more info can be found on the fork I created here: [GitHub - sroebert/swift-armv7: Swift runtime for Linux Armv7](https://github.com/sroebert/swift-armv7) ---

I also have a Buildroot fork that integrates Swift as proper Buildroot packages. > **[GitHub - MillerTechnologyPeru/buildroot at 2022.02-swift](https://github.com/MillerTechnologyPeru/buildroot/tree/2022.02-swift)** > > 2022.02-swift ---

@sroebert I updated the repo for Swift 5.7.1.

I've taken all this a step further and built Swift for different versions of Debian and Ubuntu: > **[Releases · xtremekforever/swift-armv7](https://github.com/xtremekforever/swift-armv7/releases)** > > Swift runtime for Linux Armv7.

My hope is that we as a community can keep supporting armv7 for new releases of Swift, until no one is using arm32 anymore. ---
