I have built a go package (https://github.com/emicklei/go-restful) and I am now trying to reference the output of that package build from my own workspace.
$GOPATH
|--src
| |-- {my source}
|--pkg
| |-- {package binaries /linux_amd64/github.com/emicklei/go-restful.a}
|--bin
|-- {my output}
but this fails to compile stating can not find package. go build is only searching the src folder as AFAIK and all the solutions I can find around this involve having the package source code, but surely it's possible to reference package binaries?
Turns out it's not possible to reference a package binary, in order to reference a package the source code is required: http://zduck.com/2014/go-and-package-versioning/
============ EDIT ==============
Turns out you can hack it so that the compiler will use the package output by placing a dummy source file in the expected location with a last modified older than the package output. (see Volker answer to original question).
