This is because tiemzone data needs glibc but glibc has not been built yet.
There is no DEPEND on glibc in timezone-data's ebuild
Comment 1 Jeroen Roovers (RETIRED) gentoo-dev 2014-07-21 19:43:31 UTC
If you need to build anything against a C library (in this case the tz tools) then build a stage3 toolchain with crossdev first:

crossdev --help:
[...]
    -s3, --stage3            Also build the C library

All the earlier stages have limited use anyway.
Comment 2 Joakim Tjernlund 2014-07-21 19:55:46 UTC
This does not help when you define ROOT to some other dir and rebuild
from scratch because then there is no glibc to start with.
(don't look at my /usr/x86_64-tm-linux-gnu/ path, it has been replaced
with a bind mount to an empty dir with only etc/portage in it)

It is quite obvious that glibc do not need timezone-data to build.
Either timezone-data should be PDEPEND or timezone-data should move into
the system profile and its dep be removed from glibc.
Comment 3 Joakim Tjernlund 2014-07-22 12:01:58 UTC
One would think thate USE=vanilla would do the trick but vanilla
blocks timezone-data so one cannot emerge timezone-data seperatly.

Please open this bug again

Comment 5 SpanKY gentoo-dev 2014-07-28 05:25:17 UTC
sys/types.h is provided by the C library.  if your compiler is broken, then random packages are expected to fail.

adding circular dependencies won't help either.  this is why we have the stage1->stage3 process, and why crossdev bootstraps a sysroot for you.

we specifically classify this as not a bug.

It is not broken, been built with crossdev, no special options.

I do use my own sysroot though as the standard sysroot has limitations:
1) you must be root to install pkgs there.
2) you can only have one active branch of development

No circluar deps. Is it not possible to only PDEPEND on timezone-data in
glibc and then add DEPEND glibc in timezone-data?

This sysroot does not always work well due to 1) and 2) above.
If the PDEPEND idea does not fly, can the RDEPEND:
  vanilla? ( !sys-libs/timezone-data )
be removed?
Then one can build glibc with USE=vanilla and you can pull in timezone-data
manually.
Comment 7 SpanKY gentoo-dev 2014-07-31 13:46:46 UTC
(In reply to Joakim Tjernlund from comment #6)

if you want to use your own sysroot, you must take care to initially seed it with a C library

crossdev needs to gain support for making it easy to create arbitrary sysroot support for users (rather than only supporting /usr/$CTARGET out of the box).  at that point i might reconsider this, but not now.

yes, this is what I am doing but the odd dependcy for timezone-data is getting in my way.
Oddly timezone-data is missing a DEPEND on glibc and glibc has 
DEPEND+="
		!vanilla? ( >=sys-libs/timezone-data-2012c )"
RDEPEND+="
	vanilla? ( !sys-libs/timezone-data )
	!vanilla? ( sys-libs/timezone-data )"

There is no real DEPEND for timezone data and why is there a:
RDEPEND= vanilla? ( !sys-libs/timezone-data )
This all feel like a workaround for something else but what?

That would be nice :)
Currently I use proot to bind mount my own sysroot over /usr/$CTARGET
Comment 9 SpanKY gentoo-dev 2014-08-05 03:57:21 UTC
(In reply to Joakim Tjernlund from comment #8)

historically glibc has provided the timezone data.  when we added the sep package, we couldn't just let every system out there stop installing timezone data entirely.  even today, there's not really a better place to express this dependency.  hence glibc depends on it.

and yes, it does utilize /usr/share/zoneinfo at runtime, so glibc RDEPEND-ing on it makes sense.  however, timezone-data does not require glibc, so it does not DEPEND on it.  it merely needs a C library.

but when you build with USE=vanilla, it goes back to glibc building+installing the timezone-data, hence blocking the sep data files also makes sense.
Comment 10 Joakim Tjernlund 2014-09-12 15:48:45 UTC
So I have tested PDEPEND now, if I do like so:
timezone-data:
 DEPEND="!<sys-libs/glibc-2.3.5"
 RDEPEND="sys-libs/glibc"

glibc:
 PDEPEND+="
		vanilla? ( !sys-libs/timezone-data )
		!vanilla? ( sys-libs/timezone-data )"

./cross-emerge -1a glibc 

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N     ] sys-libs/glibc-2.19-r1 to /usr/x86_64-tm-linux-gnu/ USE="-debug -gd -hardened -multilib -nscd -profile (-selinux) -suid -systemtap -vanilla" 
[ebuild  N     ] sys-libs/timezone-data-2014f to /usr/x86_64-tm-linux-gnu/ USE="-nls -right_timezone"


It works really nice!
Would you consider adding this to timezone-data and glibc?

I don't understand why I have to add RDEPEND="sys-libs/glibc" to
timezone-data to make portage emerge timezone-data after glibc.

Since glibc-2.19-r1 has a timezone-data dependency in RDEPEND, emerge attempts to satisfy that dependency before it builds glibc-2.19-r1. Therefore, it builds timezone-data first.

But I changed that RDEPEND to PDEPEND to prevent that. Still timezone-data
is pulled in first.

In the absence if circular dependencies, PDEPEND behaves much like RDEPEND. So, the changes that you suggested in comment #10 look reasonable to me.
Comment 15 SpanKY gentoo-dev 2014-09-16 04:29:19 UTC
i can live with it being in PDEPEND:
http://sources.gentoo.org/sys-libs/glibc/glibc-2.20.ebuild?r1=1.2&r2=1.3

the latest glibc still builds & installs tzcode progs (not tzdata zoneinfo files), so the blocker is still necessary otherwise

What is then in timezone-data:
 DEPEND="!<sys-libs/glibc-2.3.5"
if not a circular dep?

BTW, is there a difference between
  DEPEND="!<sys-libs/glibc-2.3.5"
and
  DEPEND=">=sys-libs/glibc-2.3.5"
?

Blockers don't create circular deps, they only specify conflicts.

Yes, they are different because a blocker specifies what must NOT be installed, without saying anything about what MUST be installed. So, the blocker atom only serves to specify a state that would result in some sort of conflict.

Right, of course. Do we still need that old blocker? 2.3.5 and older are long
gone in the tree. 

That should have been RDEPEND and changing that to
 RDEPEND=">=sys-libs/glibc-2.3.5
makes the new PDEPEND in glibc work as intended.
Having just 
  DEPEND=">=sys-libs/glibc-2.3.5"
has no effect on PDEPEND which I still find a bit odd. 
timezone-data should DEPEND on glibc too as it also
has a build dep on glibc.

I wonder if we can change all glibc ebuilds to PDEPEND and then
just update timezone-data too?

I'll let the toolchain herd / Mike answer that.

When ROOT!=/ the DEPEND behavior depends heavily on your use of the --root-deps option (the cross-emerge wrapper probably uses it).

> timezone-data should DEPEND on glibc too as it also

Yes, that seems reasonable to me. However, Mike has already expressed his own reasoning for the opposite (that you MUST use a sysroot or seed stage instead).

That's for the toolchain herd / Mike to decide.

Right, I had forgot about just using --root-deps, doing that,
a DEPEND=glibc will be enough to pull in timezone-data after glibc

Yes, but this is a step in the right direction to be able to drop that and
it is backwards compatible(or so I think).

  Yes

     Perhaps we this report now can loose the INVALID status?

Thats better :)

timezone-data do need an actual RDEPEND&DEPEND on glibc to make
the PDEPEND in glibc work as intedend though.
Can one have:
RDEPEND="!sys-libs/glibc[vanilla(+)]
         sys-libs/glibc[vanilla(-)]"
? (unsure about the syntax)

I think it is safe to change all glibc's to PDEPEND as it stands
today. Then one can start moving timezone data over to xDEPEND on glibc

So I did some experiments, using sys-libs/glibc-2.20 and sys-libs/timezone-data-2014g

Adding 
 DEPEND="sys-libs/glibc[-vanilla]"
 RDEPEND="${DEPEND} !sys-libs/glibc[vanilla(+)]"
to timezone-data appears to work but this was not an exhuastive test though.
Not sure why !sys-libs/glibc[vanilla(+)] ?

Thar should be 
DEPEND="virtual/libc"
RDEPEND="${DEPEND} !sys-libs/glibc[vanilla(+)]"

As long there isn't a dependency on glibc, portage is allowed to merge
any of glibc's PDEPENDs before glibc itself.

sounds fine to me.  i guess that means we're back to the point where relying on emerging glibc w/out glibc won't work

Yes, we never left that state. I don't see why you are reluctant to add
DEPEND/RDEPEND on glibc. To me there are only upsides:
1) timezone-data has as real DEPEND and RDEPEND on glibc
2) Adding that will ensure that glibc is built before timezone-data
   which will ensure timezone-data is built against the correct glibc
3) Also makes it possible to start with an empty SYSROOT(and ROOT?)

I honestly do not see what might break?

Gentoo, by design, does not list virtual/libc in packages.  the # of packages in the tree that "need a C library" is so significantly high that adding such a dep is completely pointless.

i don't find the fact that it helps out in the initial sysroot bootstrap case compelling enough here as we've never made the guarantee that will work.

Yes, I have noticed that. I didn't know that it wasn't allowed at all though.
I figured one could add libc xDEPEND if there was a real need for it, as
is the case here.

I know, but this is a step in the right direction, no need to make any
guarantees yet.
