Hopefully someone can help with this;
I have an extension library which basically adds some common financial
functions from gnumeric. This has worked
just fine for a couple of years on a 32 bit machine running 8.1.0. and still
does. I have recently built a new
dual core 64 bit gentoo system with 8.1.0 installed.
The library in question compiles and links just fine. I install it in
/usr/lib.
When I execute the create or replace function call that also succeeds
however when I execute
the command .. for example:
select * from eomonth('10/22/2006',0);
1. Is there anything special I should have done when building postgres ?
