When I tried to launch the server with the given command, it said,

 iMac:minecraft_server user$ LD_LIBRARY_PATH=. ./bedrock_server
 -bash: ./bedrock_server: cannot execute binary file

On linux, it said the same thing.

I even tried to delete the

LD_LIBRARY_PATH=. 

 but still the same error.

I don't have a windows machine that I can use for the server, since I live in a Mac (and Mac's running Linux) only household (with an exeption for my brother's gaming laptop and my mom's work laptop).
