Re: FW: NPTL support on PPC32 (MPC5200) ?

From: Jim Freeman <hidden>

Possibly related (same subject, not in this thread)

The attached script (wrapper/setup to crosstool.sh) gets me
a toolchain sufficient to build the default-config ppc kernel
(2.6.8.1, NPTL, gcc-3.4.2, glibc-2.3.3).

It tweaks the patch Dan references below for a ppc-ism,
then adds a patch (thanks Google!) to mask an issue that
gcc-3.4.2 has with inline functions calling setjmp() ( see
http://mirrors.mathematik.uni-bielefeld.de/pub/linux/suse/ftp.suse.com/pub/projects/powerpc/ftp.linuxppc64.org/pub/people/janis/old/README.20040130
)

The toolchain build fails near the end while linking
build-glibc/elf/sln with undefined references to
`_Unwind_Resume' and `__gcc_personality_v0' (which Google
hints is/was a popular problem, but I don't have time to
track it down).  In any case, 'sln' isn't needed for kernel
building, so it's good enough for me for now.

Hi Stephen,
to build NPTL, you need to apply 
contrib/crosstool-0.28-rc34-nptl_fixes.patch
Then see demo-x86_64-nptl.sh

Enough people need this that I've been intending for two weeks to merge it 
asap,
but I haven't gotten around to it.

That patch was only tested for x86, but ppc32 shouldn't be any
harder, right? :-)

Hi. I'm attempting to use your crosstool to build a NPTL capable GLIBC
and toolchain for a 32-bit PowerPC target.

Thanks for any pointers at all!

My question is - can anybody tell me, or point me at a website that
definitively tells me:

1) Is NPTL available on PPC at all? I assume so, since I found one of
the original announcement of NPTL, which mentions performance on a large
SMP PPC system.
