Unfortunately, the patch you mentioned doesn't seem to address the problem. I'm getting the following compile error:
|
||
|
|
|
||
|
|
Data/Digest/SHA2.hs:111:4:
|
||
|
|
Could not deduce (Show a) arising from a use of `showHex'
|
||
|
|
from the context (Integral a)
|
||
|
|
bound by the instance declaration at Data/Digest/SHA2.hs:109:10-39
|
||
|
|
Possible fix:
|
||
|
|
add (Show a) to the context of the instance declaration
|
||
|
|
In the first argument of `(.)', namely `(showHex a)'
|
||
|
|
In the expression:
|
||
|
|
(showHex a)
|
||
|
|
. (' ' :)
|
||
|
|
. (showHex b)
|
||
|
|
. (' ' :)
|
||
|
|
. (showHex c)
|
||
|
|
. (' ' :)
|
||
|
|
. (showHex d)
|
||
|
|
. (' ' :)
|
||
|
|
. (showHex e)
|
||
|
|
. (' ' :)
|
||
|
|
. (showHex f) . (' ' :) . (showHex g) . (' ' :) . (showHex h)
|
||
|
|
In an equation for `showsPrec':
|
||
|
|
showsPrec _ (Hash8 a b c d e f g h)
|
||
|
|
= (showHex a)
|
||
|
|
. (' ' :)
|
||
|
|
. (showHex b)
|
||
|
|
. (' ' :)
|
||
|
|
. (showHex c)
|
||
|
|
. (' ' :)
|
||
|
|
. (showHex d)
|
||
|
|
. (' ' :)
|
||
|
|
. (showHex e)
|
||
|
|
. (' ' :)
|
||
|
|
. (showHex f) . (' ' :) . (showHex g) . (' ' :) . (showHex h)
