How Can I Create Shared Libraries (.so) in Go?

Creating Shared Libraries in Go

Creating shared libraries (.so) is now feasible in Go with the introduction of the -linkshared flag. To achieve this, follow these steps:

1. Shareable Packages Preparation:

   • Execute go install -buildmode=shared -linkshared std to make standard packages shareable.

2. User-Defined Package Compilation:

   • Compile your custom package using go install -buildmode=shared -linkshared userownpackage.

3. Program Compilation:

   • Finally, compile your program with go build -linkshared yourprogram.

By utilizing dynamic linking instead of static linking, the compiled file size is significantly reduced. For example, a "hello.go" file would be reduced from 2.3MB to 12KB.
