Can Go Create Shared Libraries (.so) Files?

Shared Libraries in Go: Exploring the Possibilities

Can Go be harnessed to create shared libraries (.so)? This question has intrigued developers, and a recent inquiry via an "issue" has shed light on a promising solution.

Unveiling the Power of -linkshared

The key to unlocking shared libraries in Go lies in the -linkshared flag. By invoking this flag during the compilation process, you can transform packages into dynamically linked assets.

To embark on this journey, begin by executing the following command:

go install -buildmode=shared -linkshared std

This command renders all standard packages shareable, paving the way for the next step.

Next, execute the following command for your own package:

go install -buildmode=shared -linkshared userownpackage

Finally, to compile your code, employ the command:

go build -linkshared yourprogram

Harnessing the Benefits of Dynamic Linking

Leveraging the -linkshared flag not only enables dynamic linking but also reduces the size of compiled files considerably. For instance, a simple "hello.go" program with static linking occupies 2.3MB, while its dynamic linking counterpart clocks in at a mere 12KB.

Conclusion

By wielding the power of the -linkshared flag, developers can now unlock the potential of shared libraries in Go, optimizing their code and unlocking new possibilities.
