Overview

This repository is a CI/CD pipeline for a collection of cross-compilation C/C++ toolchains that produce static binaries, carefully optimized for maximum hardware compatibility and small size.

These toolchains are ideal for training, research, debugging, CI and development of cross-platform software.

Usage

Pre-built toolchains are available here.

To install a toolchain, extract it to /opt/x-tools, e.g.:

curl -L https://github.com/dimkr/toolchains/releases/latest/download/arm-any32-linux-musleabi.tar.gz | sudo tar -xzvf - -C /

Each toolchain is accompanied by a venv-style "activation" script that sets environment variables.

For example, to build static strace binaries for ARM:

HOST=arm-any32-linux-musleabi
. /opt/x-tools/$HOST/activate
curl https://strace.io/files/5.4/strace-5.4.tar.xz | tar -xJvf-
cd strace-5.4
./configure --host=$HOST
make

Another way to use the toolchains is using the Meson build system: each toolchain has a matching cross-file under /usr/local/share/meson/cross.

For example, to build papaw for ARM:

HOST=arm-any32-linux-musleabi
git clone --recursive https://github.com/dimkr/papaw
cd papaw
meson --cross-file=$HOST build
ninja -C build
