Creating Shared Libraries in Go
Shared libraries, or dynamic link libraries (.so files), allow separate programs to share common code and data, saving memory and improving performance. While C and C languages have long supported creating shared libraries, it is less straightforward in Go.
Is it possible to create shared libraries in Go?
Yes, it is possible to create shared libraries in Go using the -linkshared flag. This flag allows the Go compiler to generate dynamic libraries instead of statically linking everything.
How to create a shared library in Go:
Run the following command to make all common packages shareable:
go install -buildmode=shared -linkshared std
Install your own package as a shared library:
go install -buildmode=shared -linkshared userownpackage
Compile your program with -linkshared flag:
go build -linkshared yourprogram
By following these steps, you can create a shared library in Go that can be used by other programs. Using dynamic linking can significantly reduce the size of your compiled file, leading to faster load times and improved performance.
