Installing Newtmgr

This page shows you how to install newtmgr from source code.

Install Go (golang)

If you have not already done so, install Go for your platform.

The easiest way on a MAC is to use brew.

brew install go
==> Downloading https://homebrew.bintray.com/bottles/go-1.5.3.mavericks.bottle.t
...
==> Summary
🍺  /usr/local/Cellar/go/1.5.3: 5,336 files, 259.6M


Alternatively, you can download binaries from the golang.org site To test your Go implementation, you can query Go for its version information

$ go version
go version go1.5.3 darwin/amd64


To use go, you must set a $GOPATH variable in your environment. This tells go where to put all the packages it downloads, builds and runs.

$ mkdir $HOME/dev
$ export GOPATH=$HOME/dev/Go


Its best to add this to your .profile so its set automatically for your environment.


Download the newtmgr source

You will first download the source code for newt.

    go get mynewt.apache.org/newt/...
        (wait a few minutes please, this sits without any indications of working)


Building newtmgr

Change into the directory where the newmgr tool was downloaded and install the newtmgr tool

    cd $GOPATH/src/mynewt.apache.org/newt/newtmgr
    go install
    $ ls $GOPATH/bin
    ... newtmgr ...


Note: If the go install command results in errors indicating some package cannot be found, do a go get to download all the third-party files needed from github.com and then run go install again.

Add to your Path

Add your $GOPATH/bin directory to your path.
