About This Fork

This is a fork of sgerrand's alpine-pkg-glibc project with minimal changes to build Alpine Linux glibc apk packages for the armhf (arm32v6) architecture, which is used by the Raspberry Pi Zero.

The glibc binaries used to build the apk packages are built by docker-glibc-armhf-builder.

To build, using an Arm based computer:

echo "_YOUR_RSA_PUBLIC_KEY_" > _YOUR_RSA_KEY_NAME_.rsa.pub
export RSA_KEY_PREFIX=_YOUR_RSA_KEY_NAME_
export RSA_PRIVATE_KEY=_YOUR_RSA_PRIVATE_KEY_
./build-with-docker.sh

The upstream readme follows:

alpine-pkg-glibc

This is the GNU C Library as a Alpine Linux package to run binaries linked against glibc. This package utilizes a custom built glibc binary based on the vanilla glibc source. Built binary artifacts come from https://github.com/sgerrand/docker-glibc-builder.

Releases

See the releases page for the latest download links. If you are using tools like localedef you will need the glibc-bin and glibc-i18n packages in addition to the glibc package.

Installing

The current installation method for these packages is to pull them in using wget or curl and install the local file with apk:

wget -q -O /etc/apk/keys/sgerrand.rsa.pub https://alpine-pkgs.sgerrand.com/sgerrand.rsa.pub
wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.32-r0/glibc-2.32-r0.apk
apk add glibc-2.32-r0.apk

Please Note

⚠️ The URL of the public signing key has changed! ⚠️

Locales

You will need to generate your locale if you would like to use a specific one for your glibc application. You can do this by installing the glibc-i18n package and generating a locale using the localedef binary. An example for en_US.UTF-8 would be:
