SuperMarioWorld sound can't be loaded (coudn't open stream)

[RunaldWaschlab]

I cloned SqAtx's GitHub repository https://github.com/SqAtx/SuperMarioWorld onto my Ubuntu 16.04 (64bit) machine. I would like to run his Super Mario clone in order to understand his project and learn by the way he did this game.
I succesfully compiled his project, but as soon as I start the executable I get the following error message:

Failed to open sound file "../../assets/sounds/Jump_Sound_Effect.ogg" (couldn't open stream)

It is much longer, the longer you let it run...

Does someone have an idea what is the problem with this?
All help is appreciated!
Thank you.

You're most likely running the compiled binary from the wrong working directory so the assets can't be found.

Since Visual Studio will place your built binaries in a folder like "x64/Debug", I'd assume all you hav eto do is modify the asset paths and remove the leading "../../" to fix this.

Okay, thanks for the help!!
I tried to do that, and when I recompile and execute it I get an error message saying Segmentation fault (core dumped)

Can you please help me with that as well? What is causing the problem, and how can I solve it?

Could be anything, you'll have to debug your program. In Visual Studio's projects settings (under "Debugging") you can also set your proper working directory, so you can simulate running the program from that specific folder.
