HI i am trying to compile a kernel for that machine but i cant, i tried with the genkernel on the first time but didnt work so i went oldschool and tried to compile but i get this error:
| Code: | # make
HOSTLD scripts/kconfig/conf
scripts/kconfig/conf -s arch/sparc64/Kconfig
CHK include/linux/version.h
UPD include/linux/version.h
CHK include/linux/utsrelease.h
UPD include/linux/utsrelease.h
SYMLINK include/asm -> include/asm-sparc64
CC kernel/bounds.s
kernel/bounds.c:1: error: -m64 is not supported by this configuration
kernel/bounds.c:1: error: -mlong-double-64 not allowed with -m64
kernel/bounds.c:1: error: -mcmodel= is not supported on 32 bit systems
make[1]: *** [kernel/bounds.s] Error 1
make: *** [prepare0] Error 2

This are my CFLAGs i used to have -mcpu=ultrasparc but i changed it to ultrasparc3
| Code: | | CFLAGS="-O2 -mcpu=ultrasparc3 -pipe" |
This is my .config file |

Hi
It would seem that in your processor section of the kernel you have enabled 64 bit options. This is having a conflict as it cant be run.. hence the is not supported on 32 bit systems.
Sugest going through the menuconfig -> processor type and features section slowly and read each options help. Check what you have selected there.
then try the make again once you have changed/fixed it.
hope that helps

Your flags are fine, but for reasons unknown standard gcc cannot handle -m64. You need to 'emerge kgcc64' if you haven't already done so (the compiler for building the kernel), then when you build the kernel, you need
make CROSS_COMPILE="sparc64-unknown-linux-gnu-" ...
And no, I don't know why upstream forced this.
