====== Building Juju on windows ======

For convenience, I will assume that the first thing you do is:

  start powershell

  * Download necessary dependencies:

  (new-object System.Net.WebClient).DownloadFile("http://go.googlecode.com/files/go1.2.1.windows-amd64.msi", "$HOME\go1.2.1.windows-amd64.msi")
  (new-object System.Net.WebClient).DownloadFile("http://bitbucket.org/tortoisehg/files/downloads/tortoisehg-2.11.2-hg-2.9.2-x64.msi", "$HOME\tortoisehg-2.11.2-hg-2.9.2-x64.msi")
  (new-object System.Net.WebClient).DownloadFile("https://msysgit.googlecode.com/files/Git-1.9.0-preview20140217.exe", "$HOME\Git-1.9.0-preview20140217.exe")
  (new-object System.Net.WebClient).DownloadFile("https://launchpad.net/bzr/2.5/2.5.1/+download/bzr-2.5.1-1-setup.exe", "$HOME\bzr-2.5.1-1-setup.exe")


  * Install dependencies

  cmd.exe /C call msiexec /i $HOME\go1.2.1.windows-amd64.msi /qb
  cmd.exe /C call msiexec /i $HOME\tortoisehg-2.11.2-hg-2.9.2-x64.msi /qb
  cmd.exe /C call $HOME\bzr-2.5.1-1-setup.exe /SILENT
  cmd.exe /C call $HOME\Git-1.9.0-preview20140217.exe /SILENT

  * Add Apropriate environment variables

  setx PATH "$env:PATH;${env:ProgramFiles(x86)}\Git\cmd;${env:ProgramFiles(x86)}\Bazaar;${env:ProgramFiles}\TortoiseHg"
  setx GOPATH "$HOME\golang"


  * set variables for current session as well. The C:\Go\bin path is set by the installer:

  $env:PATH += ";${env:ProgramFiles(x86)}\Git\cmd;${env:ProgramFiles(x86)}\Bazaar;${env:ProgramFiles}\TortoiseHg;C:\go\bin"
  $env:GOPATH = "$HOME\golang"
  mkdir $env:GOPATH

  * Get juju-core and its dependencies

  go get -v github.com/juju/juju/...
  

  * Install and run godeps

  go get -v launchpad.net/godeps
  & $env:GOPATH\bin\godeps.exe -f -u $env:GOPATH\src\github.com\juju\juju\dependencies.tsv


  * run install

  go install github.com/juju/juju/...


:!: IMPORTANT NOTE :!: DRAGONS AHEAD :!:

If you ever get a bunch of errors like the following while compiling:

  conflicting definitions for @

Simply:

  rm -Recurse -force $env:GOPATH\pkg\windows_amd64

and try again.
