Any ideas why I cannot build native valgrind ? http://pastebin.com/e2h6AWxN
"Missing or unbuildable dependency chain was: ['valgrind-native',
'glibc-dbg-native']"
Also tried bitbake glibc-dbg . nothing provides that, but it is required
in recipe

The short answer is because valgrind doesn't have a native form yet.
Presumably you added BBCLASSEXTEND=native yourself, so you get to fix it. :)
valgrind RRECOMMENDS $(TCLIBC)-dbg as without debugging symbols it's fairly
useless, and TCLIBC is the variable for the libc being used (in your case,
glibc). As a recommends, it will be built.
However, native recipes don't usually depend on the C library (base.bbclass
handles the addition of those core dependencies, and doesn't run on native
builds) so you've hit a new corner case.
The easy fix would be to remove the recommends in the native build case:
RRECOMMENDS_${PN}_class-native = ""
Surprisingly enough it then builds!
Also remember that we strip the native sysroot, so if you want a native
valgrind to be useful in any way you'll have to disable that too
(INHIBIT_SYSROOT_STRIP).
(it would probably be easier to use the host valgrind, to be honest)

Hi Ross,
many thanks for nice explanation. At my shallow research, I notice, that
valgrind is somewhat special demanding packages with debugging symbols,
sooo... I actually don't need all packages to be unstripped. Only those
I am developing and testing. Therefore i might need create some class
that will require debug symbols.
And, propalby I will also need glibc with DBG symbols... or not ?
"Presumably you added BBCLASSEXTEND=native yourself, so you get to fix
it. :)"
Indeed, I did so ;-]

Yes, if you set INHIBIT_SYSROOT_STRIP then all of the sysroots will be
unstripped, but you'll want all the debug symbols for the libraries that
are used from the host (such as glibc).
