Cross-compiling to the RPi4 using Whisk

Whisk for the RPi4

To get started you'll need linux (WSL will also work on Windows)

Prerequisites

• whisk buildsystem.
• arm-linux-gnueabihf-gcc arm cross-compiler. (or aarch64)
  

$ sudo apt-get install gcc-arm-linux-gnueabihf

Building

To build the project (for the Pi) simply run:

$ whisk build . arm-linux-32 # or aarch64-linux-64

You can also build the project for your own machine: (as long as you're on x86 64 bit linux)

$ whisk build

$ whisk run

Debugging

For debugging you'll need gdb, if you don't have it yet.
Install it (on Debian) using sudo apt install gdb.

You can debug the program locally in vscode using F5. (don't forget to whisk build first)

Uploading

To upload your program to the Pi I recommend using scp.
It is a command line tool for uploading files over ssh.

Example usage:

$ scp ./bin/whisk-rpi usr@127.0.0.1:/home/usr/Desktop

Notes

Don't forget to chmod +xwr ./whisk-rpi on the Pi after uploading it.
Otherwise you will get a Permission denied error when attempting to run it.

That's it, it's that simple, have fun programming! :D
