How to work from home, Codam edition. 2020-03-13

The Codam staff has recommended everyone to work from home if possible. Because not everyone has a development environment setup to work from home, I thought I would create a quick guide.


In order to collaborate with your peers, screen sharing could be useful. For this, you can use the “Start a call” button at the top right of any slack channel. Anyone who is on that channel can join your call. One person can share their screen at a time and everyone can draw on that screen to e.g. point to code.

If you wish to share more then one screen at a time you could use Discord.

If you use vscode you can also use the Live Share plugin to collaborate as if you shared an iMac.

Migrating from vogsphere to GitHub

If you only have your code on vogsphere you can push it to GitHub in a few steps.

  1. Create a GitHub repository
  2. cd to the folder on your iMac where you have your repo.
  3. git remote add github
  4. git push -u github master

If you have 2FA on your GitHub you need to use SSH instead of https. How to setup. The url will look like


If you don’t have a macOS device (like me) and want to work from home you probably want to use Linux. Windows users can use WSL to get a Linux environment.

I recommend Ubuntu for new Linux users. First, you want to install Git and the build-essential package.

sudo apt install git build-essential

build-essential contains all the required tools to compile C code on Linux. You may also choose to use the clang compiler instead of gcc, which will give more similar error messages to what we use at Codam. To do so, install the clang and lldb packages.

sudo apt install clang lldb

If your makefile uses the $(CC) variable instead of calling gcc or clang directly, you can choose which compiler to use by setting the CC environment variable. See my Makefile tutorial for details.

In some cases, the Linux code and macOS code need to be different. For this you can use the #ifdef statement. For example, if you want PATH_MAX you need to include it like this:

#include <ft_printf.h>
#include <libft.h>
#ifdef __linux__
# include <linux/limits.h>
# include <limits.h>
#include <unistd.h>
#include "env.h"
#include "builtin.h"
