The answer to both of the questions is that I followed this examples from
the ssa <https://godoc.org/golang.org/x/tools/go/ssa> package
(LoadWholeProgram):
// Load, parse, and type-check the whole program.
cfg := packages.Config{Mode: packages.LoadAllSyntax}
initial, err := packages.Load(&cfg, "fmt", "net/http")
if err != nil {
log.Fatal(err)
}
It implies that a list of packages (or package paths) needs to be passed to
the Load function. Otherwise, I am not sure how would the tool know what to
load, particularly that the GOPATH is set to the tool itself and not to the
codebase that the tool analyses.
FYI, Michael Matloob answered this question in the golang-tools
<https://groups.google.com/forum/#!topic/golang-tools/hIRQ60on35M> list and
it seems like it is a legit problem that should be filed as a bug.
