Hello, thanks for help, -m32 option to Makefile and make was successful, so was also make test & make install. Our own tests are connecting to postgres - at least so far. Tom,we are using 32-bit perl & 32-bit postgres on 64-bit RHEL4, because some of our sw still are 32-bit. DBD::Pg is the latest version 2.10.7 from CPAN. Again, thanks for great help !

Yes, the problem must be that the compiler produces 64-bit code which cannot be linked with 32-bit code. You can either install 64-bit PostgreSQL libraries or give gcc the -m32 option so that it generates 32-bit code. Yours, Laurenz Albe
