#!/usr/bin/env zsh # # This script does not have a stable API. # # Usage: mbuild [-b git-ref] [kernel-arch]... # # Builds a bunch of gitstatusd-* binaries. Without arguments builds binaries # for all platforms. git-ref defaults to src. # # Before using this script you need to set up build servers and list them # in ~/.ssh/config. There should be a Host entry for every value of `assets` # association defined below. VMs and cloud instances work as well as physical # machines, including localhost. As long as the machine has been set up as # described below and you can SSH to it without password, it should work. # # ===[ Build Server Setup ]=== # # Linux # # - Install docker. # $ apt install docker.io # adjust appropriately if there is no `apt` # $ usermod -aG docker $USER # not needed if going to build as root # - Install git. # $ apt install git # adjust appropriately if there is no `apt` # # macOS # # - Install compiler tools: # $ xcode-select --install # - Install homebrew: https://brew.sh/. # $ bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)" # # FreeBSD # # - Install git. # $ pkg install git # # Windows # # - Disable Windows Defender (optional). # ps> Set-MpPreference -DisableRealtimeMonitoring $true # - Install 64-bit and 32-bit msys2: https://www.msys2.org/wiki/MSYS2-installation/. # - Open each of them after installation, type `pacman -Syu --noconfirm` and close the window. # - Then run in powershell while having no msys2 or cygwin windows open: # ps> C:\msys32\autorebase.bat # ps> C:\msys64\autorebase.bat # - Install 64-bit and 32-bit cygwin: https://cygwin.com/install.html. # - Choose to install 32-bit to c:/cygwin32 instead of the default c:/cygwin. # - Select these packages: binutils, cmake, gcc-core, gcc-g++, git, make, perl, wget. # # IMPORTANT: Install msys2 and cygwin one at a time. # # IMPORTANT: msys2 builder can reboot the build machine. # # Option 1: OpenSSH for Windows # # - Install OpenSSH: https://docs.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse. # ps> Add-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0 # ps> Start-Service sshd # ps> Set-Service -Name sshd -StartupType 'Automatic' # - Enable publickey authentication: https://stackoverflow.com/a/50502015/1095235. # ps> cd $env:USERPROFILE # ps> mkdir .ssh # ps> notepad.exe .ssh/authorized_keys # - Paste your public key, save, close. # ps> icacls .ssh/authorized_keys /inheritance:r # ps> notepad.exe C:\ProgramData\ssh\sshd_config # - Comment out these two lines, save, close: # # Match Group administrators # # AuthorizedKeysFile __PROGRAMDATA__/ssh/administrators_authorized_keys # ps> Restart-Service sshd # # Option 2: OpenSSH from WSL # # - Install WSL. # - Install Ubuntu. # - Install sshd. # $ apt install openssh-server # $ dpkg-reconfigure openssh-server # $ cat >/etc/ssh/sshd_config <<\END # ClientAliveInterval 60 # AcceptEnv TERM LANG LC_* # PermitRootLogin no # AllowTcpForwarding no # AllowAgentForwarding no # AllowStreamLocalForwarding no # AuthenticationMethods publickey # END # service ssh --full-restart # - Add your public ssh key to ~/.ssh/authorized_keys. # - Make `sshd` start when Windows boots.
