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



Vasek

Hi Uwe



The Makefile has:

OTHERLDFLAGS =  -L"/dbsystem/II/ingres/lib" -lingres -lrt



That is the correct path for this installation.

Hi,



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 ...
