Game with postgreSQL


I developed this game a bit long ago, and would like to share with the world.

Yes, ofcourse, we can optimize the code of c here, but i have concentrated only on desired functionality for this. Once, i got the desired result, i haven't looked into any of the line in this code. {Very bad habbit, i need to over come this.}

I hope you enjoy it, and correct if any problems occurs.

This game is for only 2 players, which will give you the realtime game feel with your opponent.

First find the code, and then instructions.

Steps to run the game

-=-=-=-=-=-=-=-=--=-=

Step 1:-

Execute above SQL in your instance and in your opponent instance.



Step 2:-

Require second player’s details in your pg_hba.conf

Create a file “/tmp/.cred”



192.168.1.2:5432:postgres:postgres:postgres => Your details.
192.168.1.3:5433:postgres:postgres:postgres => Your opponent details.

Syntax:- ::::

Caution: - Don’t provide any dbname/user/password which is having “:” symbol. 



Step 3:-

If you have the PGHOME=/opt/PostgreSQL/9.0 then game.c will work fine. If you don’t have, then please change the header file “/opt/PostgreSQL/9.0/include/libpq-fe.h” in game.c accordingly.



Step 4:-




export LD_LIBRARY_PATH according to your 9.0 instance.
Ex:-
export LD_LIBRARY_PATH=/opt/PostgreSQL/9.0/lib






Step 5:-
