OCaml Graphics Demo

A simple project showcasing the graphics package of OCaml

Building and Running This Project

To build, run

make clean && make

To run the test application, after building the project execute

./bin/demo

and follow the instructions on the screen.

Installing OCaml Graphics

If you followed the initially provided instructions for installing the OCaml infrastructure on your operating system, the project should be working. Otherwise, follow the instructions below.

This project relies on OCaml's graphics package, which is somewhat non-trivial to install, due to native system dependencies. Some instructions on how make it work are provided below:

Mac OS X

1. Install XQuartz.

2. Log-out from the system and log-in again.

3. After that, you will have to re-install all packages you have previously installed via opam. For instance, first try

   opam switch
   

   If your version is, for instance 4.10.0, next run

   opam switch reinstall 4.10.0
   

   It will take a while, as it re-builds all packages from scratch.

   The graphics package has been checked to work with OCaml 4.06.1, 4.07.1, and 4.10.0.

4. Next, execute

   opam update; opam upgrade
   opam install graphics
   

   After that you should be able to build the project.

5. You might need to install core, and batteries via opam (using opam install .).

Linux

1. Make sure that x11 window manager is installed (it comes as a part of most of the standard distributions).

2. Proceed to Step 3 for Mac OS X (above).

Windows (Cygwin)

1. As it seems to be the case, x11 graphic interface is included into Cygwin (https://x.cygwin.com/).

2. Proceed to Step 3 for Mac OS X (above).
