Setup

Host setup

macOS

brew install nanomsg --HEAD
brew install python3 rsync cmake
curl https://sh.rustup.rs -sSf | sh

VM setup

VirtualBox is the preferred virtualizer, although any other virtualizer that can provided shared folders and port forwarding will also work.

Debian 9 Stretch is the distro of choice.

• Set up port forwarding

  22 → 2222 (SSH forward)

  SSH keys are recommended

• Set up shared folders

  → Folder name: 9001d
  → Path: <absolute path to 9001d>

• Enable symlinks in shared folders

   VBoxManage setextradata <vm-name> VBoxInternal2/SharedFoldersEnableSymlinksCreate/<share-name> 1

  Restart VirtualBox to apply this change.

• Start VM

• Insert guest additions CD

• Install guest additions

   # Dependencies
   sudo apt-get install curl build-essential module-assistant dkms pkg-config
  
   # Prepare system to build kernel modules
   sudo m-a prepare
  
   # Mount Guest additions CD and build
   sudo mount /dev/sr0 /mnt
   cd /mnt
   sudo ./VBoxLinuxAdditions.run
  
   # Allow current user to access shared folders
   sudo adduser "$USER" vboxsf
  
   # Reboot
   sudo reboot

• Setup cross-compile environment

  make commands can now be issued on the host machine if port forwarding was set up properly,

   make setup

Cross-compiling

Use make build (on host) to generate foreign binaries and make transfer (on host) to copy them over to the target.

Environment Variables

• TARGET_ADDRESS
  Address of machine that the compiled binary should be deployed on.
  Example: pigeon9001.local
• TARGET_BIN_LOCATION
  Target location of the deployed binary.
  Example: '~'
• TARGET_USER
  Username on target system.
  Example: philip
• VM_PORT
  SSH port of cross-compile VM.
  Example: 2222
• VM_PROJECT_LOCATION
  Shared project folder location.
  Example: /media/sf_9001d
• VM_USER
  Username on cross-compile VM.
  Example: philip
• CONFIGURATION
  Defaults to debug, set to release for optimized builds.
  Example: release
• TARGET
  Defaults to armv7, set to arm for ARMv6 builds.
  Example: arm

Run make env (on host) to generate a .envrc containing all required environment variables.

Use something like direnv to automatically run this file.
