Blocking waiting for file lock on build directory

This means that some other process is currently doing a build or a check. This could be your IDE doing a "cargo check on save" (VSCode with rust-analyzer will do this, for example)

= note: ld: library not found for -lSDL2

Did you install SDL2 library first? Here are a bunch of instructions for various different platforms here, as well as instructions for using a "bundled" SDL2:

I'm currently using the SDL2 binding for Rust and that works well. And looking at the error message, i agree with previous message : your SDL2 dev maybe is not installed. I recommend to you using the installing of SDL2 library with your package manager if you are on Linux system. And if you want to try a C program to be sure that the SDL2 is really found, you can use this command : gcc -o myprogram myprogram.c `sdl2-config --cflags --libs` (take care to the ` character).

Thanks for the quick solution, now it's working. Happy :slight_smile:
