Hi everyone!

I'm trying to transfer an entire project from a computer to another;

Project is developed on Lazarus, plus Zeos to connect to a Postgresql
database;

I installed all the mess using the same settings used in the first
computer, but I don't know if the Postgres instalation requires some
special configuration to work with Zeos;

THE ISSUE:

When I try to turn the connection to True, at dev time, Lazarus yields
"Access Violation" error; When debugging, I catch the SIGSEGV error;

I kept the same settings about protocol and stuff; I've found some
guys talking about DLL as drivers and so on, but I still didn't find
any related docs on Zeos documentation;

Thanks in advance.

I debugged the "ZConnection1.connected:=True" code closer, so caught a
message of "libpq.dll is missing";

So, I've found this solution:

(Environment Variables Settings - Postgres didn't that automatically)
