Cross compilation

This directory contains utilities to build a toolchain to be used to cross-compile packages.

Build the toolchain

First make sure blimp-builder has been built. Go to its directory and use:

cargo build --release --features network

Then, you can specify the target triplet for which the toolchain compiles with the TARGET environment variable. Example:

export TARGET="x86_64-unknown-linux-musl"

Then, in this directory use build.sh to build the toolchain:

./build.sh

This may take a while. When done, the toolchain is available in the toolchain/ directory.

The environment to use the toolchain can be set using:

TARGET="<target-triplet>" source ./env.sh

The TARGET environment variable is used by env.sh to determine the target to compile for.

Then, blimp-builder can be used to cross compile packages.
