[Galaxy Note 3 Q&A, Help & Troubleshooting] Atifbaig786:
,I am trying to build my first kernel and ran into an erro.I do not understand what went wrong and need your help.Here is the output:

+:A note that I am trying to build an android kernel because of a sound mod patch that will enable sound modification.I requested on xda to build it and after 6 months I thought I had the hardware and I should have a shot at it.

Also I am using the latest GCC with it.
