Open the '''WinPython Command Prompt''' <br>
Navigate to the SVN checked out relax folder.<br>
First we need to run the variable setup '''[http://msdn.microsoft.com/en-us/library/f2ccy3wt(v=vs.110).aspx vcvars32.bat] or [http://msdn.microsoft.com/en-us/library/x4d2c09s.aspx vcvarsall.bat''' ] for Microsoft Visual Studio 11.0, before we can compile.
cd C:\WinPython27\relax_disp
"C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin\vcvars32" "C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\vcvarsallx86"
scons
(Scons will automatically find CL.exe, and setup compilation for 64 bit.)
