Can Go Libraries Be Distributed as Binary Packages (.a) Without Source Code?

Distributing Binary Packages in Go

Question:

Is it possible to distribute a Go library as a binary package (.a file) without the source code?

Answer:

Yes, it is possible to distribute a Go library as a binary package without the source code. However, users will need to invoke the compiler manually to use the package.

Solution:

• Build your library to create the .a file.
• Ship the .a file and a dummy source file with an older timestamp than the binary.
• Ensure that the source file contains the package declaration and no actual code.

Technical Details:

• The Go compiler requires source files even when using binary packages.
• The dummy source file tricks the compiler into thinking that the source code is available.
• Newer versions of the go tool may require all source files with the correct filenames and timestamps.
• Managing the timestamp on the dummy source file is not difficult.

Additional Considerations:

• While distributing binary packages without source code is technically possible, it is generally not recommended.
• Distributing source code allows users to inspect the code, make modifications, and resolve any issues.
• Go is an open-source language, and the availability of source code promotes transparency and collaboration.
