perl DBD::TEXIS driver

wtian · Post by **wtian** » Wed Apr 18, 2001 3:12 pm

We have full version of TEXIS and want to implement functions using perl.
I understand that the perl driver is not fully supported but hope for some help here.

I got some error/warning message during compile. The test phase just wont go through. The message during "make test TEST_VERBOSE=1" is something like this (not just this one, but that are all similar):
---------------------------------------------------------------------------
t/01base............install_driver(TEXIS) failed: Can't load 'blib/arch/auto/DBD/TEXIS/TEXIS.so' for module DBD::TEXIS: dlopen: blib/arch/auto/DBD/TEXIS/TEXIS.so: symbol "Perl_no_modify" unresolved at /usr/local/lib/perl5/5.6.1/alpha-dec_osf/DynaLoader.pm line 206.
at (eval 1) line 3
Compilation failed in require at (eval 1) line 3.
Perhaps a required shared library or dll isn't installed where expected
at t/01base.t line 14
------------------------------------------------------------------------------
I even tried copy TEXIS.pm and TEXIS.so to the perl library tree where perl can find them. The driver will load but them I got core dump when I try some thing like this:
----------------------------------------------------------------------
#!/usr/bin/perl
use DBI;
use DBD::TEXIS;

$database="/usr2/httpd/html/database/testing";

DBI->trace(9);
my $dbh = DBI->connect("DBI:TEXIS:$database")
------------------------------------------------------------------------------------

I can tell that the dbd tar ball we got was version 0.93 and compiled under 5.00404. I have the newest perl
(5.6.1) which I understand is what I should do. I compiled perl without backward binary compatible option. Just as I was told to do somewhere in the document.

Please let me know which version of perl is supported. If you have a new version of DBD driver, where can I get it. Detailed error message is available if they may help.

Any help is sincerely appreciated.

Currently the only version of Perl that we know that version will run with is the version it was compiled under (5.00404).

John,

With Perl constantly changing as it is, is there any version flexibility is there with our DBD or do we have to rebuild Texis for every Perl upgrade?

Currently there are at least three different namespaces in Perl, and currently our DBD needs Texis to be recompiled for each. We are planning to improve the flexibility which should allow it to run with any fairly recent version.

Thanks.

It is working after I installed perl5.00404.

John, Your last message seems suggest that perl support is compiled in texis binarys.
Maybe your "recompile" means that the driver need to be revised? I found that the non-compatible issue with new perl release also exists for some other DBDs. But not all of them.

I do not know details involving a DBD driver, is it possible to build a dll(so) for texis and use them? Then, the DBD should be able to be writen in pure perl which use the loadable lib, or even user applications.
I thought DBD::TEXIS is built on the texis API. Just some thoughts.

I am glad to hear that you are planing on working on the DBD.

Yes, the shared library approach is what will be needed to make it work.
