Hello sir,
Whenever I compile the following sample code
# include <stdio.h>
# include <pgsql/libpq-fe.h>
void
exit_nicely(PGconn *conn)
{
PQfinish(conn);
exit(1);
}
main()
{
char *pghost,
*pgport,
*pgoptions,
*pgtty;
char *dbName;
int nFields;
int i,
j;
/* FILE *debug; */
.........
}
i get a compilation error which is of the following
/tmp/ccTCPDUs.o(.text+0x77): undefined reference to `PQstatus'
