I’ve seen the line in the docs that mentions how to build from source:
If you want to install from source, you can use
go getto install to$GOPATH/bin.
go get -v github.com/dgraph-io/dgraph/dgraph
But there doesn’t seem to be any way to build a specific version. I’ve also tried checking out the repo locally, switching to the desired commit, and using go build inside of the dgraph/ directory, but that doesn’t fetch dependencies automatically. What is the right way to do this?
Hi @KevOrr,
Yes, you are right in the fact that go get does not provide a way to checkout a specific version.
The approach you took is the right one:
go get the repositoryGOPATH (I’m assuming you’re not using modules)git checkout $VERSIONgo install ./....Let us know if you need anything else!
Hi @francesc, i tried this steps but it finished with errors.
Here is what I did (everything is running in Docker - docker run -it --rm golang bash).
go get -v github.com/dgraph-io/dgraph/dgraph
cd /go/src/github.com/dgraph-io/dgraph/
git fetch --all --tags --prune
git checkout tags/v1.0.15-rc9 -b version
go install ./dgraph/

Any suggestion?
Thanks for your reply @francesc. Installing master this way works:
~ $ mkdir /tmp/go
~ $ export GOPATH=/tmp/go
~ $ go get github.com/dgraph-io/dgraph/dgraph
~ $ cd /tmp/go/src/github.com/dgraph-io/dgraph
/tmp/go/src/github.com/dgraph-io/dgraph $ go install ./...
# github.com/dgraph-io/dgraph/contrib/embargo
loadinternal: cannot find runtime/cgo
/tmp/go/src/github.com/dgraph-io/dgraph $
But when trying to checkout a commit before installing:
~ $ mkdir /tmp/go
~ $ export GOPATH=/tmp/go
~ $ go get github.com/dgraph-io/dgraph/dgraph
~ $ cd /tmp/go/src/github.com/dgraph-io/dgraph
/tmp/go/src/github.com/dgraph-io/dgraph $ git checkout v1.0.14
Note: checking out 'v1.0.14'.

It appears that some dependencies have changed between v1.0.14 and master, and go get wasn’t aware of those dependencies since it saw the repo at master.
Edit: wow haha @selmeci good timing
In my case, I managed to build v1.0.14 in this way.
# at first build "master"
go get -v github.com/dgraph-io/dgraph/dgraph
# fetch target source of dgraph
cd $GOPATH/src/github.com/dgraph-io/dgraph/
git checkout v1.0.14
# in my case (v1.0.14), old? opencensus source is needed.
cd $GOPATH/src/go.opencensus.io/
git checkout v0.20.x
# I did go get again. go install is not sufficient???
go get -v github.com/dgraph-io/dgraph/dgraph
In this way, output of “dgraph version” command is not correct, so I want to know how to build specific source using make command.
