I tried to use libpq this morning and all it can do is crash. I have
Postgresql running on my local machine and have installed the ODBC drivers,
not that that matters at this point. I can't seem to get past the call to
connect to the database.:
my code looks like:
PGconn * connection;
char conninfo[250];
sprintf(conninfo, "user=%s password=%s dbname=%s hostaddr=%s
port=%d", "user", "password", "foo", "192.168.3.3", 5433);
qDebug() << "Foo1: " << conninfo;
connection = PQconnectdb( conninfo );
qDebug() << "Foo1: ";
And I get
The program has unexpectedly finished.
