[perl #29612] ndbm failure in make test

# New Ticket Created by clock [at] twibright
# Please include the string: [perl #29612]
# in the subject line of all future correspondence about this issue.
# <URL: http://rt.perl.org:80/rt3/Ticket/Display.html?id=29612 >

This is a bug report for perl from clock [at] twibright,
generated with the help of perlbug 1.34 running under perl v5.8.0.

-----------------------------------------------------------------
[Please enter your report here]

Following the INSTALL instructions doesn't yield flawless perl compilation
on all systems.

On my system, make test fails on 5 tests all with problems with ndbm.

/home/clock/perl-5.8.4-bad/perl: relocation error: ../lib/auto/NDBM_File/NDBM_File.so: undefined symbol: dbm_open
# STATUS: 32512
# Failed at run/fresh_perl.t line 53

ndbm is present on my system:
clock [at] beto:~$ locate ndbm
/usr/include/db1/ndbm.h
/usr/include/gdbm/ndbm.h
/usr/include/ndbm.h
/usr/lib/libndbm.a
/usr/lib/libndbm.so
/usr/lib/perl5/site_perl/5.8.0/i686-linux/ndbm.ph

It is provided by gdbm. I ensured up-to-date version of gdbm is installed
by freshly reinstalling gdbm (gdbm-1.8.3), removing perl source and trying
everything again. I also did ldconfig after reinstalling gdbm. I also don't
have full disk.

Thanks for your report. I was hoping someone else would answer since
I'm not a linux user myself, but rather than let the silence continue,
I will stick my neck out and hope someone else will correct me.

Looking at the hints in ext/NDBM_File/hints/linux.pl, it seems that
perl is of the opinion that the libndbm.a library is to be avoided and
the compatibility routines in libgdbm.a used instead.

However, I thought that as of gdbm-1.8.1, the compatibility routines
were moved to a separate library libgdbm_compat.a. I see no sign of
perl's configuration process checking for or using this library
(except with cygwin), but I do see several linux bug reports where the
library is being linked; this implies to me that some linux
distributions are getting Configure to do so.

So, are you sure the libndbm* files are from your fresh gdbm
installation? If so, commenting out the $self->{LIBS} = line in the
linux hints file may help; if not, and there are the libgdbm_compat*
files, changing it to say -lgdbm_compat may help. Please let us know
the results.

Also, please send output from the ./myconfig script in your build
directory. The info attached to your report was from a 5.8.0
installation. For future reference, you can run "make nok" to
generate a bug report using the failed build's information (or just
email your report to perlbug [at] perl with the ./myconfig output
attached, assuming at least the Configure stage was successful).

Oops -- we need the ./myconfig from your 5.8.4 installation attempt.

Unfortunately, where different Linux distributions have put the libndbm
library has varied considerably over the years, and suggested patches to
improve detection have often been incomplete and/or inconsistent, since
there is no one true way to do it. Life is further complicated by the
split between dbm packages and dbm-devel packages. You need the -devel
forms to actually compile in NDBM support.

However, Configure does try to find dbm_open() by itself before deciding
to include NDBM_File. The usual occurence, if ndbm doesn't look like
Configure expects, is that Configure simply fails to find dbm_open() and
doesn't suggest to use it.

Still, we need to see the ./myconfig output and the output of
'grep dbm config.sh' before making too many wild guesses.
