p.s. is there a way to identify which perl module supplies the
Perl_Gthr_key_ptr symbol? perhaps it's just a dependency issue
that didn't exist in 10.04 but is somehow in 11.04.
That symbol would be defined in libperl.so and is on my system.. It
sounds very much as if this software is not playing nicely. Does it
have its own version of perl, perhaps embedded? Is it messing with
LD_LIBRARY_PATH or something similar?
i think i'm close, just need another push. i tried building all my
host tools on this system and the build of git still failed with the
same error i've seen before:
/home/rpjday/WindRiver/prj/4.3/vrf_host/host-cross/bin/perl
Makefile.PL
PREFIX='/home/rpjday/WindRiver/prj/4.3/vrf_host/host-cross'
/home/rpjday/WindRiver/prj/4.3/vrf_host/host-cross/bin/perl: symbol
lookup error: /usr/lib/perl5/auto/Cwd/Cwd.so: undefined symbol:
Perl_Gthr_key_ptr
Makefile:41: *** [perl.mak] Error 127
and now another google shows me this:
https://bugs.archlinux.org/task/24575
ah, so the build might just be picking up the totally wrong Cwd.so
file, and a quick find shows, yes indeed, there are two of them on
my system:
/usr/lib/perl/5.10.1/auto/Cwd/Cwd.so
/usr/lib/perl5/auto/Cwd/Cwd.so
and checking which packages they belong to:
$ dpkg -S /usr/lib/perl/5.10.1/auto/Cwd/Cwd.so
perl-base: /usr/lib/perl/5.10.1/auto/Cwd/Cwd.so
$ dpkg -S /usr/lib/perl5/auto/Cwd/Cwd.so
libfile-spec-perl: /usr/lib/perl5/auto/Cwd/Cwd.so
$
and it seems clear that the build is picking up the second one of
those. any guesses that the first one is the right one? and what
would be the proper solution here? if i try to remove
libfile-spec-perl, apt-get tells me that's the only package that
would go so dependencies wouldn't be an issue.
If you run 'perl -V' from the command line and look at @INC you should be able
to detect the order in which the /usr/lib/perl* directories are searched.
and why would i have ended up with two packages each containing
Cwd.so? that sounds like a recipe for confusion and badness. but i
don't want to delete anything just yet until i'm feeling more
confident.
I've actually two similarly placed CWD.so's on my system so I am not entirely
sure it is a bug in your system - it would seem the software you are trying to
install isn't very friendly but that could simply be a result of your trying to
tie it into software it doesn't want to use i.e. your Ubuntu installed Perl
versus the perl binary that came with the software.
If the software came with its own binaries and environment then you really
should try building using what it expects to use. I wouldn't declare it a bug
in your system nor a bug in the software. The bug, such as it is, is the way
you are trying to solve the problems you're encountering. Been there, done
that, got the T-shirt ;)
Good luck
