Go build vs. Go install: What's the Difference and How Do They Handle Executable Placement?

Understanding the Difference Between "go build" and "go install"

The documentation for "go build" and "go install" briefly mentions their functions, leaving users with questions about their specific actions.

The Role of "go build"

"go build" is responsible for compiling the source code into an executable file. It places this file in the current directory where the command was executed.

The Functionality of "go install"

"go install" performs additional actions beyond compilation. It not only compiles the executable but also:

• Moves the executable file to "$GOPATH/bin"
• Caches non-main packages imported during the build process in "$GOPATH/pkg"

This cache enhances subsequent compilations by utilizing prebuilt packages that haven't undergone recent changes.

Can "go install" be Customized to Place Files Elsewhere?

Unlike "make install," "go install" automatically places files in predefined locations. There is no option to specify an alternative destination.

Alternative Approaches

Rather than attempting to modify the behavior of "go install," consider using a Makefile to achieve the desired outcome. This approach allows for custom configuration and provides flexibility in file placement. For example, a Makefile could compile the executable and move it to a specific location outside of "$GOPATH/bin."
