Greetings All,
I hope that this post will not be considered off topic for Sun
Managers. The reason I'm posting here is that I believe that my problem
must be something related to my system setup and not Perl or the Perl
module in question. If you believe this to be off topic, please hit
delete now (or flame me if it'll make you feel better <grin>), as this is
a rather lengthy post. Anyway, here's the details...
There is a Perl module (CIsam-1.0) which I have downloaded from CPAN.
I successfully installed the module on our development server, an Ultra 2
running Solaris 2.8 and a third party app called Vista. Vista, BTW, uses
DIsam files, a variation on CIsam by a company called Byte Designs. In
any case, the module installed without a problem on the development
server. Our programmers have been using it for about a month now to
access the DIsam files from Perl. The steps I performed to install the
module on the development server were: 1) edited Makefile.PL as follows:
use ExtUtils::MakeMaker;
# See lib/ExtUtils/MakeMaker.pm for details of how to influence
# the contents of the Makefile that is written.
WriteMakefile(
'AUTHOR' => 'Ilya Verlinsky ilya@wsi.net',
'ABSTRACT' => 'Object Oriented Interface to C-ISAM files',
'NAME' => 'CIsam',
'VERSION_FROM' => 'CIsam.pm', # finds $VERSION
'LIBS' => ['-lm -ldisam'], # e.g., '-lm'
'DEFINE' => '-DCISAM4', # e.g., '-DHAVE_SOMETHING' if
you use Informix C-Isam v.4.xx do '-DCISAM4'
'INC' => '-I/opt/disam96/head', # e.g.,
'-I/usr/include/other'
'PMLIBDIRS' => [ 'lib', ${BASEEXT}, 'eg' ],
);
2) edited CIsam.xs and changed "#include <isam.h>" to "#include
<disam.h>", 3) ran "perl Makefile.PL", 4) ran "make", 5) ran "make
test" (all tests passed), 6) ran "make install". As I mentioned above,
no problems.
One of our programmers has a Perl program which is ready to move to
production. Therefore, yesterday I attempted to install the very same
Perl module on our production server, an E4500 also running Solaris 2.8
and the same version of Vista (and DIsam) as the development server. I
should also point out that we are using the stock Perl that Sun ships with
Solaris on both servers and we are also using the same Sun Forte compiler
(v6) on both (we have a site license and NFS mount it from another
server).
Since the Makefile.PL and CIsam.xs were the only two files I modified
on the development server, I copied them to the production server and ran
"perl Makefile.PL". Here's the output:
Checking if your kit is complete...
Looks good
Note (probably harmless): No library found for -ldisam
Writing Makefile for CIsam
The note is not harmless, however, as the subsequent "make" returns
warnings and the "make test" fails:

at test.pl line 11
BEGIN failed--compilation aborted at test.pl line 11.
*** Error code 255
make: Fatal error: Command failed for target `test_dynamic'
I have double-checked everything I can think of. The DIsam libraries
exist and are in the same location on both servers. Since we are running
the same Solaris, same Vista, same DIsam, same Perl, same Perl module,
same C compiler, etc. on both servers, I began to suspect it must be an
environment problem. Therefore, on the development server I executed "set
> dev.env", then copied that file to the production server and sourced it.
I then ran "make clean" followed by "perl Makefile.PL" on the production
server and got the exact same warnings / errors.
One thing I have noticed (by running diff on them) is that the
Makefile produced by "perl Makefile.PL" is slightly different (two lines)
on the two servers. On the development server there are two lines which
read:
EXTRALIBS = -lm -ldisam
LDLOADLIBS = -lm -ldisam
On the production server those same two lines are:
EXTRALIBS = -lm
LDLOADLIBS = -lm
Seems relevant, doesn't it? The Makefile contains the following
warning, however:
# This Makefile is for the CIsam extension to perl.
#
# It was generated automatically by MakeMaker version
# 5.4302 (Revision: 1.222) from the contents of
# Makefile.PL. Don't edit this file, edit Makefile.PL instead.
#
# ANY CHANGES MADE HERE WILL BE LOST!
#
Now, why running "perl Makefile.PL" produces different output in the
first place is a mystery to me! However, I decided to try copying the
Makefile from the development server to the production server and
rerunning the "make". The "make" failed with:
ld: fatal: library -ldisam: not found
ld: fatal: File processing errors. No output written to
blib/arch/auto/CIsam/CIsam.so
*** Error code 1
make: Fatal error: Command failed for target
`blib/arch/auto/CIsam/CIsam.so'
I'm stuck. Does anyone have any ideas why this might be failing on
the production server? I'd really appreciate any help anyone can give me,
as I am supposed to leave on vacation Friday afternoon and need to get
this working before then! Thanks everyone; summary to come...
