Hello,
Last time I got such an error, it was because I was using 'read' for a
type I had defined myself, deriving Read, but on something that was not
reelated to the type. For instance:
data Foo = Foo deriving (Read, Show)
x :: Foo
x = read "Bar"
Do you use read somwhere?

Hi all,
I created a cabal project with the attached cabal file. I run:
cabal configure --enable-tests cabal build cabal test
and then I get the error:
cabal: Prelude.read: no parse
I'm not sure how to debug this any further. If I execute:
./dist/build/scientific-pl-testsStub/scientific-pl-testsStub
with any input I've tried (numbers, array notation, string notation, etc.) and I get that same error.
I can post the whole project if that is helpful.
Thanks for the debugging tips!
