Hi all,
I'm trying to build current mainline git with gcc version 4.4.1 as a
cross compiler and I'm getting the following:
CC arch/powerpc/kernel/ptrace.o
{standard input}: Assembler messages:
{standard input}:1619: Error: junk at end of line: `1'
{standard input}:2074: Error: junk at end of line: `1'
{standard input}:2742: Error: junk at end of line: `1'
{standard input}:2855: Error: junk at end of line: `1'
{standard input}:2943: Error: junk at end of line: `1'
{standard input}:4699: Error: junk at end of line: `1'
{standard input}:4794: Error: junk at end of line: `1'
{standard input}:4915: Error: junk at end of line: `1'
{standard input}:4985: Error: junk at end of line: `1'
{standard input}:5087: Error: junk at end of line: `1'
make[2]: *** [arch/powerpc/kernel/ptrace.o] Error 1
make[1]: *** [arch/powerpc/kernel] Error 2
make: *** [sub-make] Error 2
Any ideas on how to deal with this? Is this a code error or a compiler
error?
Chris

It could be either can you:
a) try the 4.6.3 cross compiler from: https://www.kernel.org/pub/tools/crosstool/
b) Try a ppc64_defconfig build.
If the newer compiler with your .config fixes it it's a compiler issue.
If chaning the config with you 4.4.1 compiler fixes it please post you
.config to see if we can work out what's going on.
Also when you say "current mainline git" I assume you mean the HEAD of
linus's tree not Ben's right?
Yours Tony

I used the 4.6.3 cross compiler for x86_64 from the above location. It
seems to be able to build arch/powerpc/kernel/ptrace.c, but then it
gives a different error:
CC arch/powerpc/kernel/epapr_paravirt.o
AS arch/powerpc/kernel/epapr_hcalls.o
CC arch/powerpc/kernel/prom_init.o
AS arch/powerpc/kernel/head_64.o
/tmp/ccnAw2ZB.s: Assembler messages:
/tmp/ccnAw2ZB.s: Internal error, aborting at
/home/tony/buildall/src/binutils/gas/config/tc-ppc.c line 6351 in
md_apply_fix
Please report this bug.
make[2]: *** [arch/powerpc/kernel/head_64.o] Error 1

Yes, that's correct.

Can you send the .s and .i files ? Also you can try with newer compilers
(there are some cross compilers on kernel.org)
Cheers,
Ben.

Here are the two files. My resuilts with a newer compiler is in my
other message.
