configure problem

[Alan secker]

I am trying to install per 5.8.3 on a Linux Mandrake 9.2 system and
failing at the confiuration stage. It seems that regardless of the
options that I select, I end up with the following:

The command the script builds to run a test file is:

gcc -0 try try.c -lnsl -lndbm -ldb -ldl -lm -lcrypt -lutil -lc ./try

The output:

/usr/lib/libndbm.so undefined reference to 'errno'
collect2: ld returned 1 exit status

Can anyone put me sraight?

TIA

Are you *sure* that's exactly the attempted command?

Cut-n-paste it, don't try to copy by hand.

OTOH if that *is* the real command, something else is
seriously messed up.

This is the cut 'n paste as generated at the end of configure:

<START>
I used the command:

gcc -o try -O3 -fno-strict-aliasing -I/usr/local/include
-L/usr/local/lib try.c -lnsl -lndbm -ldb -ldl -lm -lcrypt -lutil -lc
./try

and I got the following output:

/usr/lib/libndbm.so: undefined reference to `errno'
collect2: ld returned 1 exit status
I can't compile the test program.
(The supplied flags or libraries might be incorrect.)

Just a guess ....
Do you have NDBM installed? Is it the most up to date version? How about
the header (development RPM) files installed?

It seems to me that this is where the problem lies. Some distros of Linux
alter the various db libraries in such a way that it takes something short
of an act of God to set things right (Berkeley DB on SuSE comes to mind -
which I had to jump through hoops to get to work right).

Like I said ... it's just a guess.

I certainly didn't have NDBS installed. In facr after shooting through
25 pages of Google I'd be surprtised if anyone has! It certainly is a
mysterious entity to nail down. I found something called NDBM_file.pl.
is that it?

As for the header files.Which header files would they be?
Sorry to be so dense.

I certainly didn't have NDBS installed.

You do, or at least you have it partly installed. You have
/usr/lib/libndbm.so, which is the NDBM shared library.

*Please* be precise. It really matters with this sort of thing. You
(almost certainly) found something called NDBM_File.pm. No, that is
not it: that is the Perl module to interface to the ndbm C library.

As for the header files.Which header files would they be?

The ndbm header files . Specifically, either /usr/include/ndbm.h or
/usr/include/gdbm/ndbm.h (according to Configure).

1. Do you have either of these files?

2. If you do, is it a symlink to somewhere else? Where?

3. Is /usr/lib/libndbm.so a symlink? Where to?

4. I take it you're using glibc... what do you get if you run
/lib/libc.so.6
(yes, I do mean execute the shared library as an executable)?

5. What do you get from
nm -D /usr/lib/libndbm.so | grep errno
?

6. If you know how, enquire of your package-management system whether
you have ndbm installed... rpm -q ndbm springs to mind, but it's
(thankfully) a long time since I last had to use rpm.

Sorry to be so dense.

That's fine: these things are not easy to understand. It is important
to be accurate, though.

You mean you actually entered the above line ??

Normally you just do as per instructions in the 'INSTALL' file (which
can be found in the top level directory of the source distro).

Building perl that way was trivial for me on Mandrake-9.1.

I would guess that the 'I' there is Configure, not Alan: this is an
extract from Configure's log.

Aaaah, yes .... I think that's a good guess

No I didn't key it in, the configure script informed that that is what
it did. Very impressive the way that interfaces with the user. On the
whole very user friendly. As t how I did it, I used the instructions
unbundled along with everything else (from the .tar, gz, .rpm etc) I'm
not in front of my machine right now, which is why I'm vague on that point.

I will follow up Ben Morrow's points within the next couple of hours.

Thanks for your help.

Quite right, I do.

No, I definitely do not have those files.

2. If you do, is it a symlink to somewhere else? Where?

3. Is /usr/lib/libndbm.so a symlink? Where to?

Yes, it points to libdb.so which in turn points to libdb.so.2.0.0

4. I take it you're using glibc... what do you get if you run
/lib/libc.so.6
(yes, I do mean execute the shared library as an executable)?

package ndbm is not installed

Is the above helping?

Right... at least on my system, which has the same version of glibc
(with threads) and has ndbm a symlink to db the same, ndbm.so *doesn't*
have the symbol errno but does have __errno_location... this is as it
were the threadsafe version of errno.

package ndbm is not installed

I think the answer is to reinstall the 'db' or 'berkeley-db' or 'db2'
package along with the corresponding '-dev' package. Sorry I can't be
more specific: I'm not familiar with how Mdk names things.

Thank you. I think you've cracked it for me. I found:
http://rpm.pbone.net/index.php3/sta...ivier Thauvin <thauvin_aerov_jussieu_fr>.html
thank provides, what looks like the answer. I'll check it out later.
Anyway, I'm very grateful.
