Why Can't Golang Load Packages with Conflicting Names?

Can't Load Package: Resolving Conflicting Package Names

When defining packages in Golang, it's crucial to adhere to the naming conventions and structure outlined by the language. This helps prevent conflicts during compilation.

In the provided scenario, the main package is defined in its own directory (main.go), while the other files (d_interface.go and d_struct_that_implements_the_interface.go) are part of a separate package called my_prog.

According to Golang's package definition rules, each directory must contain its own distinct package. Therefore, the error message "can't load package: package my_prog: found packages my_prog (d_interface.go) and main (main.go)" indicates that the my_prog folder cannot have both main and my_prog packages defined within it.

To resolve this issue, the main package should be moved to its own directory. This ensures that all files belonging to the same package are grouped together in a single directory, which is the recommended approach for organizing Golang code for clarity and maintainability.
