How to compile golang program with .a file (without source)

问题

I need to compile my program - main.go with package bigPak without source. Exist only bigPak.a tnto GOPATH/pkg.

Can you give me example of compile main.go with bigPak.a ?

回答1:

That's dead simple: Just produce a fake bigPak package in the right $GOPATH/src location (an empty package bigPak will do) and (important!!) make sure this synthetic source has a modification time before the modification time of bigPak.a. The go tool should just work like this.

Go is designed to be able to compile from the .a files without transitively reading their includes. The Go tool uses the source (only) to check if an .a files needs to be recompiled (because the source is newer.
