Problems building 2.6.31.6 with 64bit Fedora-11

Problems building 2.6.31.6 with 64bit Fedora-11

[Reg Clemens]

OK, Im new to Fedora-11, and this will be my first 64bit
kernel build, so this is probably going to be something
stupid, but I dont see it.

The top of my .config file reads:

---

#
# Automatically generated make config: don't edit
# Linux kernel version: 2.6.31.6-PPS
# Thu Nov 19 20:08:27 2009
#
CONFIG_64BIT=y
# CONFIG_X86_32 is not set
CONFIG_X86_64=y
CONFIG_X86=y
CONFIG_OUTPUT_FORMAT="elf64-x86-64"
CONFIG_ARCH_DEFCONFIG="arch/x86/configs/x86_64_defconfig"
CONFIG_GENERIC_TIME=y
CONFIG_GENERIC_CMOS_UPDATE=y
CONFIG_CLOCKSOURCE_WATCHDOG=y
CONFIG_GENERIC_CLOCKEVENTS=y

--- 

So it seems that I am really doing a 64bit build, but the problems
start with the first cc/ld, viz

So whats going on here?
Why the file-format-not-recognized ???

[andrew hendry]

What arch are you building on?

What does 'file' say about the bad object files?
eg file vmlinux.o
vmlinux.o: ELF 64-bit LSB relocatable, AMD x86-64, version 1 (SYSV),
not stripped

Re: Problems building 2.6.31.6 with 64bit Fedora-11

[Reg Clemens]

I sent this message to the list yesterday, but it never appeared,
Probably a side effect of my new Fedora-11 install.  In any case
here is another try. The question is about a failue of a build
of linux 2.6.31.6 on a 64bit Pentium 4.

a 64bit Pentium 4.

A File shows:

reg@deneb kernel]$ file *.o
microcode.o:       ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not 
stripped
microcode_amd.o:   ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not 
stripped
microcode_core.o:  ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not 
stripped
microcode_intel.o: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not 
stripped
test_nx.o:         ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not 
stripped

while nm shows

[reg@deneb kernel]$ nm *.o
nm: microcode.o: File format not recognized
nm: microcode_amd.o: File format not recognized
nm: microcode_core.o: File format not recognized
nm: microcode_intel.o: File format not recognized
nm: test_nx.o: File format not recognized

Almost looks like the wrong version of nm, but Im sure someone
out there will have a better idea.
