What is the difference between Go's static and dynamic linking for library dependencies?

Go supports both static and dynamic linking for library dependencies.

Static linking involves including the entire library into the executable at compile time. This means that the resulting binary contains all the necessary code and libraries, so it can be run on any machine without requiring the library to be installed separately. However, this approach can result in larger binary sizes and longer compilation times.

Dynamic linking, on the other hand, involves linking to the library at runtime. This means that the binary only contains a reference to the library, and the actual library code is loaded at runtime. This approach results in smaller binary sizes and faster compilation times, but requires the library to be installed separately on the target machine.

Go's build system, **go build**, supports both static and dynamic linking through the use of build tags and linker flags. By default, Go uses dynamic linking for external dependencies, but this can be changed using the **-linkmode** flag. Additionally, Go supports cross-compilation, so it is possible to build a binary for a different operating system or architecture and link it statically or dynamically as needed.
