g++ problem with -l option and PostgreSQL
- by difek
Hi
I've written simple program.
Here a code:
#include <iostream>
#include <stdio.h>
#include <D:\Program Files\PostgreSQL\8.4\include\libpq-fe.h>
#include <string>
using namespace std;
int main()
{
PGconn *conn;
PGresult *res;
int rec_count;
int row;
int col;
cout << "ble ble: " << 8 << endl;
conn = PQconnectdb("dbname=db_pm host=localhost user=postgres password=postgres");
if (PQstatus(conn) == CONNECTION_BAD) {
puts("We were unable to connect to the database");
exit(0);
}
}
I'm trying to connect with PostgreSQL.
I compile this code with following command:
gcc -I/"d:\Program Files\PostgreSQL\" -L/"d:\Program Files\PostgreSQL\8.4\lib\" -lpq -o firstcpp.o firstcpp.cpp
This command is from following site:
http://www.mkyong.com/database/how-to-building-postgresql-libpq-programs/
And when I compile it I get following error:
/cygnus/cygwin-b20/H-i586-cygwin32/i586-cygwin32/bin/ld: cannot open -lpq: No such file or directory
collect2: ld returned 1 exit status
Does anyone help me?
