The ability to create shared libraries will be in Go 1.5 in August 2015¹.

From "The State of Go" talk by Andrew Gerrand:

Shared libraries

Go 1.5 can produce Go shared libraries that can be consumed by Go programs.

Build the standard library as shared libraries:

$ go install -buildmode=shared std

Build a "Hello, world" program that links against the shared libraries:

$ go build -linkshared hello.go
$ ls -l hello
-rwxr-xr-x 1 adg adg 13926 May 26 02:13 hello

Go 1.5 can also build Go programs as C archive files (for static linking) or shared libraries (for dynamic linking) that can be consumed by C programs.

_{¹ Note, gccgo already had limited support for this for some time, Go 1.5 will be the first time this is supported by the regular go build tools.}
