I don't see this one in the deps list in the gyp file. Also 'g722' and 'ilbc'
are in therem but you're missing them. I think the deps list should be the same
for GN. Maybe it's better to try and remove them from the gyp list, since they
appear to be not necessary?

[charujain, 2016/07/27 08:32:13]

If you look at "audio_coding_deps" defined at top of gn file you will find g722
and ilbc defined there. 

[phoglund, 2016/07/27 08:45:48]

You are right, they should be added by the logic there since build with mozilla
will be false (and it makes sense to just add ilbc if we're actually building
ilbc).
