[PATCH oe-core] valgrind: add powerpc to the compatible host and add eglibc-dbg in rdepends

[PATCH oe-core] valgrind: add powerpc to the compatible host and add eglibc-dbg in rdepends

[b19537]

From: Zhenhua Luo <b19537@freescale.com>

    1. add powerpc into the compatible host list
    2. valgrind requires the non-stripped eglibc libraries, so add eglibc-dbg
       into RDEPENDS

So I might be completely off-base here having never tried it, but what if 
you're using uclibc?

Hello Paul,

May I know what's the concern with eglibc instead of uclibc?

So my concern is, if you add a runtime dependency on eglibc-dbg to valgrind 
and you've selected uclibc instead, it will force installation of eglibc when 
you install valgrind (not to mention building it when you build valgrind); 
this is almost certainly not what you want.

If a dependency on the libc debug packages is really needed you could do 
something this instead:

RRECOMMENDS_${PN} += "${TCLIBC}-dbg"

(I suggest using RRECOMMENDS here rather than RDEPENDS in case here is no such 
debug package for the user's selected libc.)

Cheers,
Paul

Or:

RECOMMENDS_libc-glibc = "glibc-dbg"

I'm not sure which one is better, but I wanted to point out the libc overrides :)

with extra R and PN, right?
RRECOMMENDS_${PN}_libc-glibc = "glibc-dbg"

This seems better since it include uclibc if that was selected...

This is only provided by eglibc now, so it leaves out uclibc... I think...

I don't really understand why valgrind is doing that at all.  Aside from
the missing _${PN} thing (which I think is a QA warning, which in turn
makes me wonder how well tested this really is) it seems as though the
libc debug symbols should be Suggests at most.  I don't think it's
reasonable to drag them in as a hard dependency for valgrind.

[Luo Zhenhua-B19537] The reason is that valgrind requires non-stripped libraries of glibc during running.

What is the failure mode if you don't have them?

Would adding these packages to RDEPENDS_powerpc and RDEPENDS_powerpc64
be more the best solution then?

What provides ld.so? That package should provide a ${PKGNAME}-dbg
which contains the debug version. This work should already be done, in
theory at least. Unless I am missing something.

This is what I am suggest. If we include valgrind in an image and the
arch is powerpc or powerpc64, we need to include ld.so with debug
symbols by default. Otherwise valgrind will not work at all. This
seems like a reasonable thing to do for these two arches.

I think we might be evading the real issue here. Which symbols are
valgrind interested in ? is this something ppc specific or general
case. Are we stripping ld.so too much ?
some of the symbols are needed to be kept for ld.so for gdb to work
and I am guessing its similar kind of issue here. If you can figure
this then we may solve this issue by just not stripping needed symbols

I think the RRECOMMENDS on ppc only is therefore the right solution for
now. 

There is perhaps a case here for splitting out the ld.so -dbg from the
rest of libc so the installation requirements aren't so large.

Richard
