linux-3.8.7 64bit build

[Giridhara RP (grp)]

I was using wrong compiler.


1.       Changed  compiler to 64bit

2.       Changed Ld to 64 bit. So, its good if we run make command under linux 64 bit.

Hi,

I am trying to build 64bit linux. .config file got created. But while compiling I get the error "unimplemented: 64-bit mode not compiled in". Any pointers much appreciated.

Step2:
bash-3.00$ make V=1 CC="gcc.c4.5.3-p0.linux" ARCH=x86_64
