This is my first attempt at using libpq, and I'm running across a strange problem. Here is my bare-bones program: #include <stdio.h> #include "libpq-fe.h" int main(int argc, char **argv) { PGconn *conn; fprintf(stderr, "connecting\n"); conn = PQconnectdb("dbname=postgres"); PQfinish(conn); return 0; } I expected this program to print "connecting", but in fact I get no output whatsoever. If I comment out the PQconnectdb and PQfinish lines, I see "connecting" as expected. What could be going on here? A few notes: - I'm running PostgreSQL 8.3.6 on Windows XP. I used the one-click installer to install. - I'm compiling the program with MinGW. I get no compiler warnings or errors. - I can connect to the database just fine using pgAdmin and the command-line client. The database is running on localhost. - I've tried adding code to see if PQstatus(conn) == CONNECTION_OK, but this hasn't been useful. Since fprintf() isn't working, I can't display a message showing the result of the comparison. - I've tried various combinations of connection options in case there was an issue with the hostname, database name, username, or password. I always get the same result: no output. - I've tried printing to stdout and to a file, but neither helped. Thanks for any help you can provide. Joey
