I think this is handled by a rul in common.gypi.

[varunjain, 2011/10/26 05:41:40]

are you referring to build/common.gypi? the exclude there is only for
use_aura=0. This one is for OS=win since we want to use clipboard_win for win.

[sky, 2011/10/26 14:01:33]

Good point. I think you should add a rule that automatically includes aurax11
when use_aura==1 and use_x11==1

Done.
