Dear Slao,

Thanks for the explanation.

I figured out what was casuing my make to fail.
Solution: move the cygwin/bin before winnt;winnt/system32 in the PATH
variable.  I recommend adding a note at the bottom of

I was able to build the postgres7.1.2-1 source and also build the
module (thanks Slao).  Evertyhing works in a windows shell...I can run my
simple test script and query the database properly:

test script:
#use Pg;
#$conn = Pg::connectdb("dbname=intake");
#if ($status != PGRES_CONNECTION_OK) {
#    print STDERR "fatal error ($status), terminated\n";
#    exit (1);
#    Pg::doQuery($conn, " select * from tbl_checklist", \(at)arreglo);
#    foreach my $i (0 .. $#arreglo) {
#        foreach my $j (0 .. $#{$arreglo[$i]}) {
#            print "$arreglo[$i][$j]\t";
#        }
#        print "\n";
#    }
#exit (0);

result from test in shell:
200005100000    121
200005100000    122
200005100000    123
200005100000    124
200005100000    128
200005100000    129
200005100000    130
200005100000    131
200005100000    132
200005100000    133
200005100000    134


Now I need to figure out how to do this in a CGI ... my cgi seems to be
hanging again where I say "use Pg;".  The browser just waits there until the
cgi times out.  I don't think Pg is being loaded properly.

here is the CGI:
use Pg;
use CGI qw(:standard);

print header;
print start_html('A PostgresSQL Example'),
      h1('A PostgresSQL Examplee2'),
      "SQL: select * from tbl_checklist",

#$conn = Pg::connectdb("dbname=intake");
$conn = Pg::new('','','','','intake');

if ($status != PGRES_CONNECTION_OK) {
    print STDERR "Error fatal en la conexion ($status), terminamos\n";
    exit (1);

$sql = "select * from tbl_checklist";
$result = $conn->exec($sql);

$t = '1';
$html3 = $t;
$align = $t;
$header = $t;
$tableOpt = 'Border';

$result->print(stdout, $header, $align, $standard, $html3, $expanded,
               $pager, $fieldSep, $tableOpt, $caption);

print end_html;

Ok, then it's clear your scripts are using the Pg driver bundled with

From the point the above affirmation was made, any reference to DBI/DBD
drivers becomes redundant. If your scripts use the Pg driver, migrating
to DBI/DBD::Pg driver could be difficult, as they should be (quite some
more than) batch changed.

Maybe yet another comment :) You must not forget to place
somewhere so that Perl is able to find it. I think the layout with
libpq.dll and pg.dll in winnt/system32 is viable. But, anyway, for any
eventual problems, here's what "make install" in "src/interfaces/perl"

$ ls -lR /usr/local/lib/perl5/site_perl/5.6.0/cygwin/
total 9
-r--r--r--   1 lao      544         18124 Sep 27  1998

-r--r--r--   1 lao      544            81 Jun 11 08:57 autosplit.ix
-r--r--r--   1 lao      544         93106 Jun 11 08:57 libPg.a

I think that a link to winnt/system32/Pg.dll in
/usr/local/lib/perl5/site_perl/5.6.0/cygwin/auto/Pg could solve any
(eventual) Perl instalation issues.

Good luck!
