sorry and please forget the name and what it is meaning for.
just look at in syntax aspect
the error : "parse error on input `|'
Failed, modules loaded: none."
linerFind :: [Int] -> Int -> MaxSA -> MaxSA --MaxSA is MaximumSubarray
linerFind xs len ms1@(MaxSA l h m) -- (MaxSA leftPosition
rightPosition maxsum)
| h<len = keepFind ms1
where keepFind ms'@(MaxSA l' h' m')=
let ms2@(MaxSA l2 h2 m2)= find' xs l' (h'+1) in
if m < m2 then linerFind xs len ms2
else keepFind ms2
|otherwise = ms1 --compiler say error is
in this line

You must have the where clause after the guards,
linerFind ...
| h < len = keepFind ms1
| otherwise = ms1
where

Formatted in this way should be compile:
linerFind :: [Int] -> Int -> MaxSA -> MaxSA --MaxSA is MaximumSubarray
linerFind xs len ms1@(MaxSA l h m) -- (MaxSA leftPosition
rightPosition maxsum)
| h<len = keepFind ms1
| otherwise = ms1
where keepFind ms'@(MaxSA l' h' m') = let ms2@(MaxSA l2 h2 m2)= find' xs l'
(h'+1)
in if
m < m2
then linerFind xs len ms2
else keepFind ms2
