importer.Default not able to find packages in $GOPATH

[Joshua Liebow-Feeser]

Hi All,

I'm trying to use the go/* packages to parse and type check Go source code. I've downloaded github.com/coreos/etcd to test this on, and I'm currently trying it out in the etcdserver subdirectory. When I run 'go build' everything works fine, but when I try to type check, none of the imports are found. For each import, I get an error like:

/home/josh/workspace/go/src/github.com/coreos/etcd/etcdserver/errors.go:21:10: could not import github.com/coreos/etcd/error (can't find import: github.com/coreos/etcd/error)

(my $GOPATH is /home/josh/workspace/go)

I'm using the default importer (importer.Default()), and I compiled my tool with the gc compiler (I tried it for both go1.5 and go1.6).

Is there something obvious that I'm missing here?

Thanks!

Cheers,

Josh

Try running 'go install' or 'go build -i' on the packages you want to analyze.

The default importer works great for packages in the standard library, which are always available in compiled form, but poorly for user packages, for which it may have been days or weeks since the most recent install.  Take a look at the golang.org/x/tools/go/loader package, which loads all packages from source.

Also, you may find this tutorial helpful: https://github.com/golang/example/tree/master/gotypes

'go install' worked; thanks a ton! I'll also take a look at the other stuff you mentioned because I'm curious about the details.
