[Autoscons-devel] fail to set target in get_target()

[Zhang Le]

I found AutoBuild.get_target(env) fail to set env['TARGET'] (after
adding a print statement):
KeyError: 'TARGET':
  File "SConstruct", line 111:
    baseEnv= BuildBaseEnvironment()
  File "SConstruct", line 78:
    Autoscons.AutoBuild.get_target(env)
  File "/home/zl/prj/pymaxent/Autoscons/AutoBuild.py", line 249:
    print env['TARGET']
  File "/usr/local/lib/scons/SCons/Environment.py", line 405:
    return self._dict[key]

I have a look at Environment.py and find TARGET is a reserved variable:

    def __setitem__(self, key, value):
        if key in ['TARGET', 'TARGETS', 'SOURCE', 'SOURCES']:
            SCons.Warnings.warn(SCons.Warnings.ReservedVariableWarning,
                                "Ignoring attempt to set reserved variable 
`%s'" % key)
I think this is a little bug.
Now I use env['HOST'] = get_target(env) as a workaround.
