Package Import Error in Go: Resolving "found packages my_prog and main"
When attempting to build a Go program, a common error that developers encounter is "can't load package: package my_prog: found packages my_prog and main." This error indicates a conflict with multiple packages sharing the same name.
To resolve this error, the following understanding is crucial:
Package Structure in Go
In Go, code is organized into packages. A package defines a set of related types, functions, and variables. Each package must reside in its own directory.
Package Import and Conflicts
When you import a package in Go, you specify its name as an identifier in the import statement. If there are multiple packages with the same name in the current directory or in the GOPATH, Go will throw an import conflict error.
Case in Question
Based on the provided code structure, you have two packages in the same directory:
Go's import mechanism is case-sensitive, meaning that main and my_prog are considered distinct packages. However, when you try to build my_prog, Go finds both packages in the current directory and raises the import conflict error.
Solution
To resolve this error, you need to ensure that each package resides in its own directory:
Once you make these changes, you should be able to successfully build the my_prog package.
