Unix and C Development Environments

MacOS

Install Xcode: https://www.youtube.com/watch?v=1E_kBSka_ec

Windows Subsystem for Linux (WSL) - recommended for Windows systems

WSL Installation Guide - Ubuntu 20.04; update to WSL 2 is not necessary

For an older more detailed tutorial see the first 8.5 minutes of https://www.youtube.com/watch?v=Cvrqmq9A3tA (summary). If you have more than one version of Ubuntu installed see WSL commands and launch configurations and example.

Post-install:

  sudo apt update
  sudo apt upgrade -y
  sudo apt install -y gcc g++ make gdb zip

  mkdir /mnt/c/osp
  cd; echo "cd /mnt/c/osp" >> .profile

The cd in .profile will go to /mnt/c/osp automatically on startup.
Files there are shared -- in MS/Win edit using WordPad, not NotePad; in WSL edit using nano.

Test Program

In a terminal window, in your osp subdirectory:

  $ wget http://fog.misty.com/perry/osp/examples/point/point.zip
  [or use curl -O if wget is not available]
  ...
  $ unzip point.zip
  ...
  $ rm point.zip
  $ cd point
  $ make
  gcc -std=c11 -pedantic -Wall -g -c main.c
  gcc -std=c11 -pedantic -Wall -g -c point.c
  gcc -std=c11 -pedantic -Wall -g main.o point.o -o main -lm
  $ ./main
  p: (1,2)
  q: (3,4)
  distance = 2.82843
  $ nano Point.h
  ...
  $ make clean
  $ cd ..
  $ zip -r point.zip point

Web-based Environments

VECR
- a1/p1.c, etc. all in one file
repl.it
- your files are public in free account, e.g. https://repl.it/@fba524de41d/point
- to use make, in edit window: F1, type: shell
- can use wget; then Run should find the files
- to edit Makefile, settings: indent type tab, indent size 8
onlinegdb.com
- use C11, set options: Extra Compiler Flags: -std=c11 -pedantic -Wall -Werror
