cannot compile linux-2.6-tip tree
Jiri Olsa
I just updated 'linux-2.6-tip' and was not able to link drivers/pnp
I bisected the issue, but not sure what happened:
(git tree git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git, x86_64 arch)

That's a strange error. Are you sure you didn't run out of diskspace or
something?

you cannot reproduce, too bad :) I'll dive into and try to find out..
disk space is fine, also checkouts before the bisected commit work fine
let me know if you're interested in any debug info, I'll provide

Could you send me your config privately

that typically happens if you Ctrl-C a parallel kernel build, and GCC
leaves around an empty .o file.
It's rare but happens. 'make clean' will cure that.

I tried make clean and it did not help..
I'm not sure if I'm not overlooking something obvious or am getting
crazy, but this is what I've done so far:
I took gcc command line for drivers/pnp/card.o and drivers/pnp/core.o
from make V=1 and run it manually ending up with this:
compile:

drivers/pnp/.tmp_core.o: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped
I checked other objects in drivers/pnp/ and for some reason the file command shows
card.o (the object which is failing) as "stripped" and others as "not stripped" ... no idea why :)
I'm probably going to clone new tree... :)

- Did you change the architecture without `make mrproper` in between?
Yes, `make clean` should cure that but ....
- Did some cross-gcc, cross-objdump, ... get in the PATH?
Save .config, `make mrproper`, put .config back, `make` and see it it
persists.

Yeah, the box I tested your config on filled up before finishing. But it
made it to the linking of the vmlinux before it died.
I did a:
$ cd linux.git
$ git checkout 2e7c0e0cafee # what you showed was the problem
$ mkdir ../tmp
$ cp ~/olsa-config ../tmp/.config
$ make O=../tmp
When it died, tmp was 7964.05 MB in size!

wow :) new tree clone with the same config works for me

I did "git clean -xdf" to wipe all out and hit the same issue
thanks,
