Hello,
I am working on Linux RH 6.0 platform.
I want use PostgreSQL as a backend. 'C' language as a front-end.
I am not able to connect to each other.
I am using libpq.
The program is :-
/*conn2.c*/
#include <stdio.h>
#include "/usr/include/pgsql/libpq-fe.h"main(){ char *pghost, *pgport, *pgoptions,*pgtty; char
*dbName; PGconn *conn; pghost = NULL; /* host name of the backend server */ pgport = NULL;
/* port of the backend server */ pgoptions = NULL; /* special options to start up the backend
* server */ pgtty = NULL; /* debugging tty for the backend server */
dbName= "template1";
/* make a connection to the database */ conn = PQsetdb(pghost, pgport, pgoptions, pgtty, dbName);
}
The compiling is ok, but linking have error.
$ gcc conn2.c -c -o conn2
No error
The program compile and linking result :-
*****************
$ gcc conn2.c -o conn2
/tmp/cchKU26L.o: In function `main':
/tmp/cchKU26L.o(.text+0x47): undefined reference to `PQsetdbLogin'
collect2: ld returned 1 exit status
*****************
How to remove this linking error, or how to make link between PostgreSQL and
'C'?
Thanks in advance
