Build toolchain for cross compile locally

[pkropachev]

Hello!

This is great job! Especially GitHub workflow with checking new release. Thanks for sharing this repo!

Am I right that I can build toolchain for required architecture locally just using e.g. alpine:edge docker container?

All is needed it's just execute:

make install TARGET=aarch64-linux-musl -j$(nproc)

No. Just doing that is not going to replicate what this workflow does as it modifies the build per target triple using these matrix settings.

The real question here is why would you want to do this? The toolchains are already published as releases.

This is more of an interest than any need to do it manually. Just to understand how it works.

[userdocs]

It's based on this https://github.com/richfelker/musl-cross-make and that's how it works.

This version is just modified to use more recent dependencies and changes specific to working as a github workflow. You could use it locally if you made manual changes to the line https://github.com/userdocs/qbt-musl-cross-make/blob/main/config.mak#L44 and set the triple config. That's not the purpose of this project though. It's not targeted to be built locally or manually. It publishes the releases I need.

These are other sources based on the upstream project,
