Windows

Prerequisites

Not necessary if you already did the previous tp, but to recall: * download and install the latest version of CMake

download here: https://github.com/Kitware/CMake/releases/download/v3.17.1/cmake-3.17.1-win64-x64.msi
!!! When installing make sure that the checkbox "ne pas ajouter cmake au PATH" is NOT checked
if you don't have it already, download and install MS Visual Studio Community Edition (free for students): https://visualstudio.microsoft.com/downloads/
- install instructions here: https://docs.microsoft.com/en-us/cpp/build/vscpp-step-0-installation?view=vs-2019
- !!! install the "Desktop development with C++"
- If you have VS already installed, you can go in Tools --> Get Tools and Features... to install "Desktop development with C++" if it is missing.

Create the Visual Studio Solution.

This step enables you to create the project file to load inside VS:

unzip the code inside a folder. Avoid to place the code in folders with spaces and accented characters.
open a Terminal and go to the directory containing the code.
execute:
md build
cd build
cmake -G "Visual Studio 16 2019" -A x64 -DCMAKE_BUILD_TYPE:STRING=Release ..
dir

if you had a different version of VS installed (not the latest) you may need to adapt the string Visual Studio 16 2019 to your version: e.g. Visual Studio 15 2017, Visual Studio 14 2015, Visual Studio 12 2013

if everything went well you should find a file named tp2.sln inside the directory.

Compile, build, execute

open tp1.sln inside VS either by double clicking on it or opening from inside VS
build the solution (Build Solution from the Build menu)
from the tp directory copy freeglut\bin\x64\freeglut.dll in build\Release
execute the code:
Select the project you want to run (e.g. robot), right click on it and select Set as Startup Project
On the menu bar, choose Debug --> Start without debugging.)

(see https://docs.microsoft.com/en-us/cpp/build/vscpp-step-2-build?view=vs-2019 for how to build, execute, etc)

Editing the code

Edit the code according to the assignments that are given, rebuild the solution and execute.

!!! You need to run the cmake line only once

!!! You need to copy the dll file only once.

Linux

Prerequisites

Not necessary if you already did the previous tp.

In order to develop with OpenGL some system packages are required (unless you are using the N7 machines):

sudo apt-get install libglu1-mesa-dev freeglut3-dev build-essential mesa-common-dev libxi-dev libxmu-dev automake

To build this code we use the CMake build system. You can install CMake from the system package manager but you need a recent version >= 3.10. Check the version that is provided by your linux distribution and if it is suitable usually you need to

```
sudo apt-get install cmake
```

otherwise you can install the binaries from here: https://github.com/Kitware/CMake/releases/download/v3.17.1/cmake-3.17.1-Linux-x86_64.sh

To install:
```
wget https://github.com/Kitware/CMake/releases/download/v3.17.1/cmake-3.17.1-Linux-x86_64.sh
chmod +x cmake-3.17.1-Linux-x86_64.sh
sudo cmake-3.17.1-Linux-x86_64.sh --prefix=/usr/local/ --skip-license
```

Build

To compile and build the code you do

mkdir build && cd build cmake .. make robot

Also,

make all

builds everything, and

make clean

cleans everything.

Execute the code:

./robot

Editing the code

Edit the code as required and then

make robot

!!! the cmake line has to be run only once

macOS

Prerequisites

In order to develop with OpenGL check if

ls  /System/Library/Frameworks/

contains OpenGL and GLUT frameworks. If not you need to install XCode from the Mac App Store, see here for more details https://developer.apple.com/support/xcode/

Install the latest version of CMake by downloading https://github.com/Kitware/CMake/releases/download/v3.17.1/cmake-3.17.1-Darwin-x86_64.dmg

Build

Same as Linux.

Editing the code

Same as Linux.
