My apologies if this is not the appropriate list for this, but the "novice" list has provided no response for weeks.
 
I'm using Visual Studios C++ Express 2008 on Windows 7 with the "standard" (pre-packaged) 64-bit Windows distribution of PostgreSQL v.9.0.4 and I am having unresolved refs when linking to libpq.lib.  The relevant elements of my program are:
 
#include "stdafx.h"
#include "libpq-fe.h"
using
namespace System;
 
int main(array
<System::String ^> ^args)
{
  ...

  char *pghost = "localhost",
        *pgport =
"5432"
,
        *pgoptions = NULL,
        *pgtty = NULL;
  char *dbName = "mydb"
;
  PGconn *conn;
  /* make a connection to the database */
  conn = PQsetdbLogin(pghost, pgport, pgoptions, pgtty, dbName, NULL, NULL);
  ...
)
 
Linking against libpq.lib in the postgres "lib" directory, the error I get is:
 
DBTest.obj : error LNK2001: unresolved external symbol "extern "C" struct pg_conn * __cdecl PQsetdbLogin( ...
 
In the project properties I have included the path to the postgres "lib" directory and listed "libpq.lib" as a linker input.

So, what am I missing?  How do Iget this thing to link without error?
