Hi everyone,

I've checked-in changes that make a number of fixes needed for Ubuntu
11.10.  To get these, do:

cvs up -dP

If you have a failed install, you'll need to do:

sudo rm -rf /opt/ltib/usr/src/rpm/BUILLD/*

and then re-try the build with:

./ltib

It works for me.

Regards, Stuart

Hi Andrew,

Good catch, that looks like the issue.  I'll poke around in lkc and see if I
can move -lncurses to the right place.
Can you stomp over it with something like?
CFLAGS="$CFLAGS -Wl,--no-as-needed"


Though this may not guarantee that --no-as-needed would be later in
the arg list than --as-needed.

I am getting the same errors here in 11.10 as well.  After a bit of
looking around perhaps this explains the cause?

Quote:
"just for future reference as this is a common problem:

oneiric uses the linker flag --as-needed by default. With this flag
correct ordering of libraries and objects on the commandline is important.
objects needing symbols must be placed before libraries providing them.
E.g. file.o and staticlib.a need symbols from libm:
wrong:
gcc -lm file.o staticlib.a
gcc will think libm is not needed and drops it, when it later encounters
the objects needing it you will get undefined references
right:
gcc file.o staticlib.a -lm

Important for autotools makefiles. Place libraries into LIBS or LDADD
variables, not in LDFLAGS"

So moving where -lncurses is in the command might fix the problem?

Hi Guys,

I've checked-in a fix for the --force-debian flag.  It seems to be
something they put in for a while and removed later (but using it as a
test does not return an error, sigh).

As far as the lkc missing symbol errors go, I can repeat this too, but
have not yet had time to look at (and likely won't have time for several
days).  If anyone else has time to dig into this I'd appreciate it.

I've installed 11.10 and I'm looking into this on the train this evening
while commuting.  I'll let you know what I find.

I am seeing exactly the same thing on Ubuntu 11.10, but haven't had a
chance to investigate.  The failing gcc line includes "-lncurses", and
a readelf on /usr/lib/libncurses.a shows defs for the unresolved
symbols.  Haven't had time to investigate it further than that yet.

There is some evidence of this having happened to folks on previous
releases of Ubuntu, also; a google turned up, for
example
http://www.linuxquestions.org/questions/linux-software-2/failure-to-install-ltib-on-jaunty-jackalope-9-04-a-771464/

I also ran into the rpmdb --force-debian problem under Ubuntu that was
reported here previously.  It's strange that the script explicitly
checks for this, but still falls over (I hardwired the test to fail in
the script to work around it temporarily, then ran into the lkc/curses
problem.)

cheers,

Hi Nagesh,

I've not seen this before, what host platform are you on?

Hi all,
I am new to ltib and trying to configure LTIB for the first time.
I am facing below error.

It seems that the errors are because of "unresolved symbols" while
linking lkc build.

Please find attached host_config.log.
