M1 gcc compile error

You're unlikely to get useful errors without posting the code that you're trying to compile.

Thanks. I ended up just trying to compile anything. The file only contained an import of stdio and printf("test"), also declaring a basic char array seems to be impossible.

I'll stick with Linux

In that example, you have not declared main(). Every program must have a main(). So you get an error saying "undefined symbol main".

This is exactly the same error that you would get on Linux.
