Hi @deveshd020, did you install SDL2 and its additional libraries (such as SDL2_image,SDL2_mixerandSDL2_ttf`)? Which Linux distribution are you running this on?

Hi @deveshd020, what kind of device are you running this on? I noticed that you are running on a 32-bit version of Ubuntu. How did you get Ubuntu 18.04 32-bit version? The issue doesn't occur to me even when I set GOARCH to 386 and there is no 32-bit version of Ubuntu 18.04 on the official website as far as I can tell. Any additional information would be helpful as well!
