Please post the whole code. I did a small test using the Perl bindings 
and code, which should be similar

my $ds = Geo::OGR::Driver('GPKG')->Create('test.db');
my $l = $ds->CreateLayer(GeometryType => 'Point');
my $f = Geo::OGR::Feature->new($l->Schema);
$f->Geometry({WKT => 'POINT (1 2)'});
$f->FID(2);
$l->CreateFeature($f);

and the result is a small database with one spatial table, which has two 
columns: fid and geom, and one row. The fid is 2 on the row.
