[Buildroot] Error building for ARM Cortex A8 - "For cortex-a8 real value is cortexa8"

[Buildroot] Error building for ARM Cortex A8 - "For cortex-a8 real value is cortexa8"

[Alireza Nematollahi]

Hello

I am trying to build "buildroot" on CentOS 6 64 bit for my ARM Cortex A8
target. I have gcc/g++ 4.2. In the settings for buildroot the only one I
change is the target type, arm and arm cortex a8. I left everything else
untouched to build a default copy.

Everytime I build I get the same error message:

I don't know what I am doing wrong or what is wrong with my set up. Can
anybody help me with this please? I am fairly new to this.

Thanks very much

You are targeting a Cortex A8 core with gcc-4.3.6, that won't work and 
it's explicitly stated so in the configuration menu when selecting the 
target architecture variante.
You need at least gcc 4.4.

Like the comment in make menuconfig says, cortex A8 is only supported
from GCC 4.4 onwards.
