[Info-ingres] Problem compiling perl DBI
Martin Bowes
Hi All,
In response to a strange situation where my programs had connected to a database, set date_format ‘dmy’ and then returned dates in the installation default multinational4 format I decided on a fresh install of Perl DBI on this platform.
The platform is: CentOS Linux release 7.9.2009 (Core)
Can anyone explain the following?
perl Makefile.PL
Configuring DBD::IngresII...
Found Ingres at : "/dbsystem/II"
Using DBI 1.627 (for perl 5.016003 on x86_64-linux-thread-multi) installed in /usr/lib64/perl5/vendor_perl/auto/DBI/
Checking if your kit is complete...
Looks good
Warning (mostly harmless): No library found for -lingres
Writing Makefile for DBD::IngresII
And $II_SYSTEM/ingres/lib/libingres.a is in existence on this host. So that message surprised me. Nonetheless it was flagged as mostly harmless so I pressed on and the compilation seemed to complete. Then I ran a test program which failed at the connect, generating the following:
install_driver(IngresII) failed: Can't load '/home/ingres/DBD/auto/DBD/IngresII/IngresII.so' for module DBD::IngresII: /home/ingres/DBD/auto/DBD/IngresII/IngresII.so: undefined symbol: __gxx_personality_v0 at /usr/lib64/perl5/DynaLoader.pm line 190.
at (eval 4) line 3.
Compilation failed in require at (eval 4) line 3.
Perhaps a required shared library or dll isn't installed where expected
at /home/ingres/scripts/perl/Classes/runDBI.pm line 336.
Anyone?

is a option -L missing?
Following option -lingres the compiler search for libingres.a,
libingres.so ... on a list of directories. The directory list is
expanded with options -L...
my makefiles use
... -L/opt/Actian/IngresII/ingres/lib -lingres ...

The Makefile has:
OTHERLDFLAGS = -L"/dbsystem/II/ingres/lib" -lingres -lrt
That is the correct path for this installation.

Hi Marty,
I'm compiling DBD::IngresII quite often on Centos 7. What I have to do is to add stdc++ library to compilation. Without this library you can’t compile IngresII.so. I’ve written to the author of this module but no response. The best option is Makefile.PL:
$opts{dynamic_lib} = { OTHERLDFLAGS => " $ld_options -lstdc++" };
Hope this helps

Hi Vasek,
Spot on! That’s solved the problem.
Thanks Heaps.
Marty
