Is there a //components directory in the NaCl repo?

[Dirk Pranke, 2015/02/05 22:55:47]

Whoops. No, of course not. I meant to clean this up but forgot. Will do.

[Nick Bray (chromium), 2015/02/05 22:52:55]

I believe the correct way to get these defines is to depend on 
"//native_client/build/config/nacl:nacl_base"
In general, every target in the NaCl repo should depend on this target. 
(Including the other ones you added.)

[Dirk Pranke, 2015/02/05 22:55:47]

Will do.
