Installing Newtmgr on Windows

This guide shows you how to install the latest release of newtmgr from binary or from source. The tool is written in Go (golang).

It assumes that you have already installed the newt tool on Windows and have the Windows development environment set up.

This guide shows you how to perform the following:

1. Install latest release of newtmgr from binary.

2. Install latest release of newtmgr from source.

See Installing Previous Releases of Newtmgr to install an earlier version of newtgmr.

Note: If you would like to contribute to the newtmgr tool, see Contributing to Newt or Newtmgr Tools.

Installing the Latest Release of Newtmgr Tool from Binary

You can install the latest release of newtmgr from binary. It has been tested on Windows 10 64 bit platform.

1. Start a MinGW terminal.

2. Download the newtmgr binary tar file from one of the mirror sites .:

   $ wget -P /tmp http://www.apache.org/dyn/closer.lua/mynewt/apache-mynewt-1.4.1/apache-mynewt-newtmgr-bin-windows-1.4.1.tgz
   

3. Extract the file:

   • If you previously built newtmgr from the master branch, you can extract the file into your $GOPATH/bin directory. Note: This overwrites the current newtmgr.exe in the directory and assumes that you are using $GOPATH/bin for your Go applications.

     tar -xzf /tmp/apache-mynewt-newtmgr-bin-windows-1.4.1.tgz -C $GOPATH/bin
     

   • If you are installing newtmgr for the first time and do not have Go setup, you can extract into /usr/bin directory:

     tar -xzf /tmp/apache-mynewt-newtmgr-bin-windows-1.4.1.tgz -C /usr/bin
     

4. Verify the installed version of newtmgr. See Checking the Installed Version.

Installing the Latest Release of Newtmgr from Source

If you have an older version of Windows or a 32 bit platform, you can build and install the latest release version of newtmgr from source.

1. Download and install the latest version of Go. Newtmgr requires Go version 1.7.6 or higher.

2. Start MinGW terminal.

3. Create a Go workspace in the /tmp directory:

   $ cd /tmp
   $ mkdir go
   $ cd go
   $ export GOPATH=/tmp/go
   

4. Run go get to download the newtmgr source. Note that go get pulls down the HEAD from the master branch in git, builds, and installs newtmgr.

   $ go get mynewt.apache.org/newtmgr/newtmgr
   

   Note If you get the following error, you may ignore it as we will rebuild newtmgr from the latest release version of newtmgr in the next step:

   # github.com/currantlabs/ble/examples/lib/dev
   ..\..\..\github.com\currantlabs\ble\examples\lib\dev\dev.go:7: undefined: DefaultDevice
   

5. Check out the source from the latest release version:

   $ cd src/mynewt.apache.org/newtmgr
   $ git checkout mynewt_1_4_1_tag
   Note: checking out 'mynewt_1_4_1_tag'.
   

6. Build newtmgr from the latest release version:

   $ cd newtmgr
   $ go install
   $ ls /tmp/go/bin/newtmgr.exe
   -rwxr-xr-x 1 user None 15457280 Sep 12 00:30 /tmp/go/bin/newtmgr.exe
   

7. If you have a Go workspace, remember to reset your GOPATH to your Go workspace.

8. Copy the newtmgr executable to a bin directory in your path. You can put it in the /usr/bin or the $GOPATH/bin directory.

Checking the Installed Version

1. Run which newtmgr to verify that you are using the installed version of newtmgr.
