Sam,

thanks for your qualified hints.
I tried as you did suggest it to me and then it works in the subdir. Then i retried with "make bzImage" and came to that point in compilation for the origin of the failure. (see appended log, "noise" on language macros an similar stripped...)

As you, and possibly others can see,
the compilation happens from the arch/i386/kernel/timers subdir, where we got lead to by th arch/i386/kernel subdir directly and in this case the needed settings seem to lack despite they were present in a former stage of the compilation.

Having a qualified fix done by a skilled person for that bad behaviour in any future standard kernel would be nice thing. Thank you so far.

-Alex.

As you, and possibly others can see,
the compilation happens from the arch/i386/kernel/timers subdir, where we got lead to by th arch/i386/kernel subdir directly and in this case the needed settings seem to lack despite they were present in a former stage of the compilation.

What happens is that the value assigned to AFLAGS_vmlinux.lds.o is lost between the first and the second invocation of make in arch/i386/kernel

The only difference is the setting of LANG etc. - which you deleted from the log.

Pleae try to delete the following lines from the top-level Makefile and try again:

line 622-626:

	$(Q)if [ ! -z $$LC_ALL ]; then          \
	export LANG=$$LC_ALL;           \
	export LC_ALL= ;                \
	fi;                                     \
	export LC_COLLATE=C; export LC_CTYPE=C; \

If this cures the problem then please provide me with you LANG settings. Both LANG and LC_* variables.

If it still fails please provide me with the _full_ unedited log up until the point where it fails.

Since I have to reports on this issue I really would like to have it nailed before 2.6.8 is out.

The other report is from: Pawe? Sikora <[email protected]>

^^^ works for me.

Thanks!

I need to track this a bit more.
Could you please provide me with information of what you are running.

make version (make --version)
shell & version of shell
distribution

Could you also try if the attached two Makefiles exhibit the same problem. Just copy them to an empty directory and execute make.

A good run looks like:
Makefile2:1: lds=-P
Hi

A bad run does not have any -P after the '='.

Needless to say my make does not exhibit this issue.

with a minor fix...
