@runningmaster Is this an issue with x/tools/cmd/gotype only? Or also with std lib gotype? (in go/types).

@griesemer

It's also with std lib gotype. I did $ go build gotype.go in go/types and replaced it gotype from x/tools/cmd/gotype. All errors are here.

@runningmaster Temporary work-around: I believe this should work if you provide the full (absolute) path name for main (/home/dmitriy/Development/go-proj/src/main in this case).

But it's clearly a bug. Fix forthcoming.

Workaround works fine for go/gotype and x/tools/cmd/gotype too.

Actually I use command go list ./... | grep -v vendor/ | xargs -L1 gometalinter in my bash file for checking my code, but gotype in this case writes errors. Now all works fine (using workaround). Thank you.

@runningmaster This has been fixed (at tip) and should not require the work-around anymore.

I have the same issue. I'm on Windows. Here is my file structure (I'm running tree from the project folder, but further down I will give the complete path to gometalinter):

I have just installed these, so this isn't an old installation. Also, here is my environment information:

@parhamdoustdar This should be fixed for 1.6. Please re-open if you still see a problem. Thanks.

I am using gometalinter embedded in atom go-plus which in turn uses gotype. Updated to latest gotype with go get -u

The directories gotype complaints no to be able to find are in place. This seems like the error has not been fixed. (Or do I need to update sthg. more but gotype?)

@the42 Please double-check this and file a new bug since 1.6 has passed. Also, please add your directory structure as otherwise it's not possible to recreate the issue if it really exists. Keep in mind that the "newest" version of gotype is in the std lib go/types directory - you need to build it yourself (there's a separate issue filed to make gotype "go get"-able again (from x/tools). I have just checked that (std lib gotype) code and I believe it's using the latest version of the go/importer which supports vendoring.

@griesemer Before opening a bug I realy think I am using the GOVENDOR-unaware gotype for x/tools. I build go from source, checking out go1.6 and bootstraping with a go1.4. How do I build the go/types gotype?

'which gotype' yields /home/john/src/gocode/bin/gotype

The project I would like to gotype has the following structure:

john@ebola:~/src/gocode/src/github.com/the42/bevaddress$ tree -d
.
├── Godeps
└── vendor
└── github.com
├── gorilla
│   └── websocket
└── lib
└── pq
└── oid

@the42 In the go/types directory just type: go build gotype.go . That will give you an executable named gotype in that directory that you can use.
