Does Go support dynamic linking?

It is not currently possible to create dynamically linked libraries* in main line Go. There has been some talk about this, so you may see support in the future.

What is dynamic linking in os?

Dynamic linking consists of compiling and linking code into a form that is loadable by programs at run time as well as link time. The ability to load them at run time is what distinguishes them from ordinary object files. Various operating systems have different names for such loadable code: UNIX: Sharable Libraries.

What is dynamic linking and static linking in os?

Static linking is the process of copying all library modules used in the program into the final executable image. Dynamic linking lets several programs use a single copy of an executable module. Static linking is performed by programs called linkers as the last step in compiling a program.

Is dynamic linking slower?

Dynamic libraries have a slower execution time and are prone to compatibility issues, but, they are really fast in the compilation time and make the executable file smaller in size (since they don’t have that massive library file to create tons of overhead).

What do you call a symbol in Golang?

A function name (as well as some additional data structures) are called symbol. The symbols hold a unique identifier for accessing, and contain “human readable” value. In order to access a symbol, there is a need to know the memory order of argument both for input and output values of the function.

How is a go plugin compiled in go?

A Go plugin is a package compiled using the -buildmode=plugin build flag to produce a shared object (.so) library file. The exported functions and variables, in the Go package, are exposed as ELF symbols that can be looked up and be bound to at runtime using the plugin package.

Who are the compilers and linkers in go?

The suites of programs that were the compilers ( 6g, 8g, etc.), the assemblers ( 6a, 8a, etc.), and the linkers ( 6l, 8l, etc.) have each been consolidated into a single tool that is configured by the environment variables GOOS and GOARCH .

When to use actors or workers in Golang?

When creating an application using Golang, it is usually a monolithic executable that holds “everything” is inside. When there is a need to separate some logic for execution, I find that many software architects prefer actors/model or workers for that.
