Can a pawn on the 7th rank prevent castling?

Every rulebook I've read doesn't seem to cover this. Does a pawn "control" a square it can't
move to, that is, an empty square on the diagonal? Can't castle thru a controlled square.
Say black wants to castle kingside, and there is a pawn on g7, black can't castle kingside, you get what I'm saying?
Dafuq? What d'ya mean?

FIDE rules:

... (2) Castling is prevented temporarily:
[a] if the square on which the king stands, or the square which it must
cross, or the square which it is to occupy, is attacked by one or more of
the opponent's pieces, or ...
Sure, but how is a pawn "attacking" a square it can't move to unless there's a piece there?
The threat is stronger than its execution!

Of course there will be piece there to take: the Rook^^

Because castling is seen as a king moving the squares individually. A king can not move into check and it would be in check if it enters a square that the pawn is attacking.

Pawns attack the square forward-left and forward-right.
The rook being under attack doesn't prevent castling, only squares the King passes thru or lands on.
I suppose I'll have to use Stockfish to set up a board in the position concerned and see what it says.
Basically, the king isn't allowed to move through check. A pawn gives check diagonally, so it counts. It is important to note that this does not apply to the rook; the b1 and b8 squares can be under attack from opposing pieces but queenside castling is still a valid move provided all castling criteria are met.
Pawns can only attack diagonally. So a pawn at g7 (for white) will prevent black from casting kingside, even if the knight and bishop are out of the way.

Does this help?

Black can castle, if rook is being attacked. Say an empty board and a bishop at a1 is attacking h8. Black can still castle kingside.
