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

[Dirk Bächle]

Hi James,

as I stated on StackOverflow already (note to other users: this question was asked there first, but then removed by its author) I 
can't reproduce the error you're seeing on my side. Neither under SuSE SLES11 with SCons 2.3.3, nor under Ubuntu Linux 14.04.03 LTS 
with SCons 2.3.5.

Is this really the full SConstruct that you're running on your side?

If yes, then why is the "print" statement not contained in it?

And why does this line number show a "69" for such a seemingly small file?

Best regards,
