Building SnackLinux from source

Toolchain

Prebuilt

1. Download the musl 1.1.6 cross compiler here. See also http://musl.codu.org/
2. Add it to your path with export PATH=$PATH:/path/to/toolchain/bin

Build your own

Compile your own toolchain with musl-cross

Compiling SnackLinux from source is done through the Makefile

Linux - 4.15.2

make kernel

musl - 1.1.18

make musl

BusyBox - 1.28.0

make busybox

Bash - 4.4.18

make bash

Binutils 2.30 (optional)

make binutils

Syslinux 6.03

make syslinux

Installing to rootfs directory

make install

If you would also like to install binutils, use:

make binutils-install

Booting

Prerequisites:

#Base files (/etc)
git clone https://github.com/snacsnoc/snacklinux-base.git
cp -R snacklinux-base/rootfs/* /opt/snacklinux_rootfs/
#Create ./dev files
./createdev.sh
#fbpkg (package manager)
git clone https://github.com/snacsnoc/fbpkg.git
cp fbpkg/src/fbpkg /opt/snacklinux_rootfs/usr/bin

ISO

Run make iso. The output ISO will be in iso/

Note: you do not have to have the toolchain to create the ISO

qemu

Create a gzipped rootfs by running:

cd /opt/snacklinux_rootfs/; find . -print | cpio -o -H newc --quiet | gzip -6 > ../rootfs.gz 

Then boot in qemu:

qemu-system-x86_64 -m 256 -kernel bzImage -initrd rootfs.gz -append "root=/dev/ram rdinit=/sbin/init"

Packages

Read the Packages page for building packages. For SnackLinux's package manager fbpkg, see here.

Hacking

Edit anything in /opt/snacklinux_rootfs, it is the root filesystem. The kernel can also be recompiled to fit your needs.

The boot/isolinux directory is where ISOLINUX resides, edit the menu to adjust to your needs.
