# Bachelor Project Questions ## Code ### Question In `main.cc:7`, there is the line ```c #include ``` But I have the compiler error that the `gdk/gdkkeysyms.h` file is not found. How do you install the `gdk`? Which version of `gtk` are you using? ### Answer (provisional) I ran the command ```bash bear -- make ``` It produced a `compile_commands.json` that the LSP uses to know which directories to include.
