[Scons-users] Variables 'Update' not adding variables to environment?

[James Ramm]

Hi
I have the following in my SConstruct:

    opts = Variables()
    opts.AddVariables(
        PathVariable('GDAL_INCLUDES', 'search path for gdal include files' ,'/usr/local/include', PathVariable.PathAccept),
        BoolVariable('DEBUG', 'compile in debug mode', 'False'),
    )

    env = Environment()
    opts.Update(env)

If I then `print env['GDAL_INCLUDES']` I get a key error:

    KeyError: 'GDAL_INCLUDES':
      File ".../SConstruct", line 69:
        print env['GDAL_INCLUDES']
      File "/usr/lib/scons/SCons/Environment.py", line 413:
        return self._dict[key]


I can, however, do `print env['DEBUG']` and it correctly writes `False`

Any idea whats going on?


Thanks
