Dependencies

• CMake
• Cinder
• Box2D
• OpenGL

Integrated Development Environment

• The development environment for this project was CLion.

Prerequisites to build and run from either the command line or through CLion

Disclaimer: This project has only been run/tested on MacOS

• Download Cinder for MacOS (assume it gets downloaded to a folder called cinder_0.9.2_mac)
• Create a subdirectory in the cinder_0.9.2_mac folder called "my-projects"
• Clone the repository into my-projects

Build and run via command line

• cd to the project directory

cd final-project-meghasg2

• Make sure CMake is in the PATH and run CMake on the project. Example:

export PATH="/Applications/CLion.app/Contents/bin/cmake/mac/bin":$PATH

• Run cmake . at the project root to generate build files

cmake . 

Build the application

cmake --build . --target cinder-myapp -- -j 4

• cd to the executable location

cd Debug/cinder-myapp/cinder-myapp.app/Contents/MacOS/

• Run the app (in this case, in debug mode)

./cinder-myapp

Build and run using CLion

• Open CLion and go to File -> New CMake Project from Sources
• Select final-project-meghasg2 and open in CLion
• Build the project in CLion
• MacOS users: it's possible that you may come across

Error running 'cinder-snake': Cannot run program … cinder-snake.app/Contents/Resources"): error=13, Permission denied

In this case, try doing Edit configurations -> Executable -> Select Other -> Find my-projects/final-project-meghasg2/cmake-build-debug/Debug/cinder-myapp/Contents/MacOS/cinder-myapp and click run once again

• You should now be able to build and run Etch-a-Sketch!
