How to compile the C++ homeworks under Linux

by Dominique Unruh

The following instructions explain how to compile the homework templates on Linux (tested on Mint 17.2 and Ubuntu 14.04.3).

Allegro-based homeworks

• Run sudo apt-get install liballegro5-dev
• Run sudo apt-get install codeblocks
• Open the homework in CodeBlocks (e.g., codeblocks HelloAllegro.cbp)
• Open the build settings (Project → Build options...)
• Find the Linker settings where "liballegro-5.0.10-monolith-md.a" is added.
• Either by selecting "Linker Settings", or by first selecting "Release" on the left and then "Linker Settings", depending on the homework file
• Remove the library "liballegro-5.0.10-monolith-md.a".
• Add the following libraries: (without the suffix ".a"):
  • liballegro
  • liballegro_primitives
  • liballegro_font
  • liballegro_main
  • liballegro_memfile
  • liballegro_color
• Clean the project (Build → Clean)
• Build the project (Build → Build)
• Run the project (Build → Run). A window with black background appears.
  • On one of my laptops, this did not work. In that case, start the program from the command line, e.g. bin/HelloAllegro (in the HelloAllegro project folder)

GLFW-based homeworks

• Run sudo apt-get install libglfw3
  • If your distribution does not have libglfw3 (e.g., Mint 17.2 and Ubuntu 14.04 have only libglfw2):
  • Add a new reposity: sudo apt-add-repository ppa:keithw/glfw3 (I give no security guarantees for untrusted repositories!)
  • sudo apt-get update
  • sudo apt-get install libglfw3
• Run sudo apt-get install codeblocks
• Open the homework in CodeBlocks (e.g., codeblocks HelloGLFW.cbp)
• Open the build settings (Project → Build options...)
• Find the Linker settings where "glfw3" and "opengl32" and "gdi32" are added.
  • Either by selecting "Linker Settings", or by first selecting "Release" on the left and then "Linker Settings", depending on the homework file
• Remove the libraries "glfw3", "opengl32" and "gdi32" (i.e., all of them)
• Add the following library ": (without the suffix ".a"):
  • GL
  • glfw (not glfw3, at least not if you have used the ppa:keithw/glfw3 repository)
• Clean the project (Build → Clean)
• Build the project (Build → Build)
• Run the project (Build → Run). A window with black background appears.
  • On one of my laptops, this did not work. In that case, start the program from the command line, e.g. bin/HelloAllegro (in the HelloAllegro project folder)
