Building Release Versions in Go: Understanding and Removing Debug Information

Unlike C, Go does not differentiate between debug and release versions of binary files. By default, the go build command incorporates symbol and debugging information into the compiled binary. However, it is possible to remove this additional data for a more optimized and efficient release build.

Removing Symbol and Debug Information

To build a release version binary without symbol or debug information, use the -ldflags flag with the -s -w arguments when compiling your Go code. The -s flag strips symbols, while the -w flag disables dwarf symbol generation. This produces a compact binary that omits detailed information that may not be necessary for production use.

go build -ldflags "-s -w"

By executing the command above, you can remove symbol and debug information for a more streamlined and optimized release version of your Go application.
