Subject: patch to install unstripped vDSO on disk breaks powerpc kernel build
Date: Fri, 09 May 2008 11:16:39 -0600 [thread overview]
Message-ID: <482486F7.3090805@nortel.com> (raw)
I'm using gcc 3.4.3 and binutils 2.15.92.0.2. I originally saw the
following problem in 2.6.25 but it's present in git head as well:
CALL /home/cfriesen/kernels/2.6.25/linux-2.6.25/scripts/checksyscalls.sh
CHK include/linux/compile.h
CALL
/home/cfriesen/kernels/2.6.25/linux-2.6.25/arch/powerpc/kernel/systbl_chk.sh
AS arch/powerpc/kernel/systbl.o
OBJCOPY arch/powerpc/kernel/vdso64/vdso64.so
BFD: arch/powerpc/kernel/vdso64/vdso64.so: The first section in the
PT_DYNAMIC segment is not the .dynamic section
/home/cfriesen/bin/ppc64-R9a/bin/ppc64-R9a-objcopy:
arch/powerpc/kernel/vdso64/vdso64.so: Bad value
BFD: arch/powerpc/kernel/vdso64/vdso64.so: The first section in the
PT_DYNAMIC segment is not the .dynamic section
/home/cfriesen/bin/ppc64-R9a/bin/ppc64-R9a-objcopy:
arch/powerpc/kernel/vdso64/vdso64.so: Bad value
make[3]: *** [arch/powerpc/kernel/vdso64/vdso64.so] Error 1
make[2]: *** [arch/powerpc/kernel/vdso64] Error 2
make[1]: *** [arch/powerpc/kernel] Error 2
make: *** [sub-make] Error 2
I installed git and bisected the problem. It turns out that it's due to
the following commit:
commit 8150caad02266623b5b9f58088d589f130fccd97

[POWERPC] powerpc vDSO: install unstripped copies on disk
This keeps an unstripped copy of the vDSO images built before they are
stripped and embedded in the kernel. The unstripped copies get
installed in $(MODLIB)/vdso/ by "make install". These files can be
useful when they contain source-level debugging information.

Anyone have any idea what's going on?
Thanks,
