Thread: DBD::Pg 2.10.7 compile failed on RH4

What it looks like to me is that you've got a 64-bit perl build ("file"
on the perl executable would be a good way to confirm that). If so,
you're going to need a 64-bit version of libpq.so to link into it.
There's no reason a 64-bit libpq wouldn't interoperate with a 32-bit
server, so just installing the 64-bit postgresql-libs RPM alongside what
you have ought to be sufficient.

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
