     12These are the most up-to-date instructions. Use these rather than the ones
     13listed further down, which are for the old OpenGL version of the game
     14
     15Windows
     16--------
     17
     18Create an include directory inside the opengl-game folder
     19
     20Download GLM and copy the glm folder into your include directory
     21
     22Download the 64bit pre-compiledbinaries of GLFW3
     23 - Copy lib-vc2019/glfw3.lib into your lib directory
     24 - Copy the whole include/GLFW directory into your include directory
     25
     26Download the SDL2 pre-built Windows binaries
     27 - Copy the SDL2 include folder into /include and rename it SDL2
     28 - Copy the contents of lib/x64 to lib
     29
     30Download the SDL2_image Visual C++ development libraries from https://www.libsdl.org/projects/SDL_image/
     31Download the SDL2_ttf Visual C++ development libraries from https://www.libsdl.org/projects/SDL_ttf/
     32(Might use SDL2_gfx later as well)
     33
     34Copy the 64-bit static libraries to the lib directory you created above
     35
     36TODO: Figure out how to do static compilation with SDL2
     37
     38Since I'm currently using dynamic SDL2 libraries for Windows, some DLLs from sdl2-ttf and sdl2-image
     39
     40Download the vulkan sdk
     41 - Add the location of the Include folder to the VS2019 project properties under C/C++ -> General -> Addition Include DIrectories
     42 - Add the location of the Lib folder to the VS2019 project properties under Linker -> General -> Addition Library DIrectories

     47Download the vulkan sdk (make sure VULKAN_SDK_PATH in the makefile points to it)
     48
     49sudo apt-get install libxcb1-dev xorg-dev libglm-dev libsdl2-dev libsdl2-image-dev libsdl2-ttf-dev
     50
     51source setup-env.sh into your current shell
     52
     53mActually, I think now this should work, after following the online instructions for installing Vulkan:
     54sudo apt-get install vulkan-sdk libsdl2-dev libsdl2-image-dev libsdl2-ttf-dev libglm-dev
     55(Follow the instructions at https://vulkan.lunarg.com/sdk/home#linux to add the latest Vulkan SDK version to apt-get)
     56(Verify that installing libvulkan-1 is not required)
     57
     58make vulkangame && ./vulkangame
     59
     60For the sfml version: (these directions need verification)
     61
     62sudo apt-get install libglm-dev libsfml-dev
     63
     64Currently, the apt-get sfml package doesn't have Vulkan support, so need to install from source as follows:
     65
     66Build the library yourself by following the instructions at https://www.sfml-dev.org/tutorials/2.5/compile-with-cmake.php
     67
     68sudo apt-get install libfreetype-dev libx11-dev libxrandr-dev libudev-dev libopengl-dev libflac-dev libogg-dev libvorbis-dev libopenal-dev libpthread-stubs0-dev
     69
     70sudo apt-get install cmake-qt-gui

     75--------
     76
     77brew install cmake pkg-config glm sdl2 sdl2_image sdl2_ttf sdl2_gfx
     78(cmake is needed for the python script mentioned below)
     79
     80Download the Vulkan SDK from https://vulkan.lunarg.com/sdk/home
     81
     82Install it by running this from inside the downloaded folder:
     83sudo ./install_vulkan.py
     84
     85make shaders
     86make vulkangame
