Kotlin/Native toolchains builder

This directory contains a set of scripts and configuration files that allow one to build the same toolchain that is used by Kotlin/Native.

System requirements

• Docker

Usage

1. First, you need to build a Docker image with crosstool-ng inside. Use create_image.sh for it.
2. Now you can build an actual toolchain. To pick one, take a look inside toolchains folder. It is organized as $TARGET/$VERSION. Then run ./run_container.sh $TARGET $VERSION $TOOLCHAIN_VERSION_SUFFIX. Building a toolchain might take a while (~17 minutes on Ryzen 5 3600). Once ready, an archive will be placed in artifacts folder. $TOOLCHAIN_VERSION_SUFFIX is an optional argument that adds suffix to the end of toolchain name.

Example

./create_image.sh && ./run_container.sh aarch64-unknown-linux-gnu gcc-8.3.0-glibc-2.25-kernel-4.9

Notes

Check that Docker can write to artifacts directory (where build_toolchains.sh places archives).
