Kernel Compiling Error - Android Q&A, Help & Troubleshooting

I'm trying to compile a kernel for my Neo V.
But it stops at error.
Error:
Code:

Why this happening?
I followed the Sony Ericsson Tutorial.

gcc and make need to be a certain version. What OS are you running?

I met the same issue in the few days ago.
But these issues had been resolved as follow solution:
1. Remove the -Wall argument in the Kernel/ Makefile
2. Copy the cc1 from eabi tool chain sub folder libexec/gcc/arm-none-eabi/4.6.1
(OR, you can create the soft link from libexec/gcc/arm-none-eabi/4.6.1 to current working directory)
