I have the corrected install instructions below, in case someone finds this post while resolving the same issue: ### Install Raylib (Ubuntu/Debian) 1. `sudo apt install libasound2-dev mesa-common-dev libx11-dev libxrandr-dev libxi-dev xorg-dev libgl1-mesa-dev libglu1-mesa-dev` 1. `cd /tmp` 1. `git clone https://github.com/raysan5/raylib.git raylib` 1. `cd raylib` 1. **`git checkout 4.2.0`** # 2022-09-14: Or the version currently targeted by `raylib-d` 1. `mkdir build && cd build` 1. `cmake -DBUILD_SHARED_LIBS=ON ..` 1. `make -j2` 1. `sudo make install` 1. `sudo reboot now` ### Add Dlang Raylib API, Build, and Run 1. Install Dlang 1. Navigate to project root directory 1. `mkdir source` 1. `touch source/app.d` 1. Code: https://github.com/schveiguy/raylib-d#example 1. `dub add raylib-d` 1. `dub build` 1. `./PROJECTNAME`
