Running glibc programs
If you want to run glibc programs in Alpine Linux, there are a few ways of doing so. You could install glibc as additional to musl (you would have to do this manually), or you could do it the easy way and use either Flatpak (the easiest) or a chroot.
Because there are different use cases, this is just a slight overview about what's possible and what's intelligent.
gcompat is the go-to compatibility layer for Alpine users.
apk add gcompat
After that you run your binaries as normal.
Flatpak is by far the easiest method of running any graphical glibc program on Alpine. Firstly install it.
sudo apk add flatpak
Then you can run any Flatpak application:
flatpak run <flatpak name>
You can then install applications from it, for example:
flatpak install com.valvesoftware.Steam
sudo apk add xz
Enter the chroot:
mkdir ~/chroot cd ~/chroot tar -xvf stage3-*.tar.xz tar -xvf portage-latest.tar.xz mv portage usr sudo mount --bind /dev dev sudo mount --bind /sys sys sudo mount -t proc proc proc cp /etc/resolv.conf etc sudo chroot . /bin/bash
And voilà, you have your working Gentoo chroot!
You can now take a look at Gentoo's Handbook to find out how you can configure and install your system, or simply extract/copy the program you need to run in your chroot enviroment and execute it.
Here is a wrapper script that is similar to
arch-chroot when you frequently reuse this chroot:
Also, create an account with the same user name as host current user to the chroot or make changes to the userspec option to chroot line.
chmod +x gentoo-chroot.sh to get it to work.
Either use pacstrap (included with the arch-install-scripts package) or an Arch bootstrap image:
sudo apk add arch-install-scripts mkdir ~/chroot && cd ~/chroot curl -O https://mirrors.edge.kernel.org/archlinux/iso/latest/archlinux-bootstrap-2021.04.01-x86_64.tar.gz sudo tar xzf archlinux-bootstrap-2021.04.01-x86_64.tar.gz && rm archlinux-bootstrap-2021.04.01-x86_64.tar.gz sudo sed -i '/evowise/s/^#//' root.x86_64/etc/pacman.d/mirrorlist sudo sed -i '/CheckSpace/s/^/#/' root.x86_64/etc/pacman.conf sudo arch-chroot root.x86_64 [chroot]# pacman-key --init [chroot]# pacman-key --populate archlinux
Once that is done, update the system and install the desired package(s) (denoted by "foo" in this example):
[chroot]# pacman -Syu foo
Use the provided debootstrap package to create the Debian chroot.
--arch is optional, depending of your needs.
On the linux-grsec kernel, you will need to relax chroot limitations:
sudo apk add debootstrap for i in /proc/sys/kernel/grsecurity/chroot_*; do echo 0 | sudo tee $i; done mkdir ~/chroot sudo debootstrap --arch=i386 wheezy ~/chroot http://http.debian.net/debian/ for i in /proc/sys/kernel/grsecurity/chroot_*; do echo 1 | sudo tee $i; done sudo chroot ~/chroot /bin/bash
You can now use
apt-get to install needed packages.
