issue building iputils with uclibc

[John Toomey]

Hello all

I'm having problems compiling iputils with uclibc -

It works fine with eglibc. Any help would be greatly appreciated!

Do you have UCLIBC_HAS_RESOLVER_SUPPORT=y
in uclibc .config ?

I dont think so, is there an easy way to check?

How would I set it to try this?

It works fine with eglibc. I posted this question before but didnt 
really get a good answer - can anyone help point me in the right direction?

IIRC the thread ended with Khem asking if UCLIBC_HAS_RESOLVER_SUPPORT='y' was 
in the uclibc configuration, the implication being that dn_comp is unavailable 
unless that is true. I'm not too familiar with how uclibc is configured and 
with only a brief glance at the recipe I can see the config seems to be 
automatically generated but I can't see exactly how additional options (beyond 
what gets added from DISTRO_FEATURES) would be added.

Khem, could you help out here?

Cheers,
Paul

go into the uclibc build tree and like kernel or busybox it will have
a .config and grok that. If this is disabled then enable it in
uClibc.distro file under uclibc recipes dir and rebuild uclibc.
ideally these are distro knobs but for tests you can try it
file ( uclibc uses kconfig )

Hi Folks

I am unable to find a .config file in the uclibc build tree, can you be 
more specific about the path i might find it at?

UCLIBC_HAS_RESOLVER_SUPPORT=y doesnt seem to be present in the 
uClibc.distro file, i added it and tried running the build again with no 
success. Is there anything else I can try?

Thanks,
John

OK, so I just gave this build a try. You can find the configuration actually 
used in the build in TMPDIR/work/i586-poky-linux-uclibc/uclibc-0.9.32-
r4.3/git/.config  (directory names may vary slightly depending on your build 
configuration). 

With master, when I checked my version of that file, 
UCLIBC_HAS_RESOLVER_SUPPORT=y is set, so apparently this feature is getting 
enabled by default. However, when I did the same on edison (which uses uclibc 
0.9.32 as opposed to 0.9.33) that setting is not present. Digging around I'm 
beginning to wonder if this option was perhaps added in uclibc 0.9.33, which 
if true would explain why it is not present when building uclibc in edison; 
but does that mean the underlying functionality was added in that version or 
just the option?

Cheers,
Paul

thats makes it clear. Its 0.9.33 feature. I was assuming thats what
you were using.

More detective work - the dn_comp() function was indeed not in uclibc until 
0.9.33; also, the reference to dn_comp() was added in the following commit to 
iputils:

http://www.linux-
ipv6.org/gitweb/gitweb.cgi?p=gitroot/iputils.git;a=commitdiff;h=ac3fe58bc1939c8ed3cf34c30f713dfe82b27ce5

So I guess you have a few options:

1) Avoid using iputils altogether - you can get very basic versions of the 
utilities in iputils from busybox. Looks like on the face of it nothing 
depends on iputils but it is pulled in via task-core-basic (which is pulled in 
by core-image-basic).

2) Upgrade to uclibc 0.9.33 (can be done in a separate layer on top of edison)

3) Patch iputils to remove the call to this function and any others that 
aren't in uclibc 0.9.32

4) Patch iputils to not build ping6

5) Build an older version of iputils

Cheers,
Paul
