Here's my simple program: #include <stdio.h> #include <libpq-fe.h> int main() { int i, j; PGconn *dbconn; PGresult *results; dbconn = PQconnectdb( "hostaddr=AN_IP_ADDR user=USERNAME dbname=SOMEDB" ); results = PQexec( dbconn, "select * from account" ); for( i = 0; i < PQntuples( results ); i++ ) { printf( "Row #%i\n", i ); for( j = 0; j < PQnfields( results ); j++ ) { printf( " Field: %16s / Value: %s\n", PQfname( results, j ), PQgetvalue( re sults, i, j ) ); } } PQfinish( dbconn ); return( 0 ); } I'm trying to compile a simple program using libpq and initially get the following linker error: -g -Wall -I/usr/local/pgsql/include -L/usr/local/pgsql/lib -lpq test.c -o test /usr/bin/ld: table of contents for archive: /usr/local/pgsql/lib/libpq.a is out of date; rerun ranlib(1) (can't load from it) make: *** [all] Error 1 After running ranlib on libpq.a, I get the following: gcc -g -Wall -I/usr/local/pgsql/include -L/usr/local/pgsql/lib -lpq test.c -o test /usr/bin/ld: Undefined symbols: _PQconnectdb _PQexec _PQfinish _PQfname _PQgetvalue _PQnfields _PQntuples make: *** [all] Error 1 Any ideas? -Stephen
