Hello,
today I tried to compile a Haskell program using m4 as preprocessor,
with the
{-# OPTIONS_GHC -F -pgmF m4 #-}
pragma on top of a .hs file. I didn't add anything else, there are no
''' or '`' in the source. Upon compiling, ghc (7.8.3) complains:
m4: cannot open `/tmp/ghc10655_0/ghc10655_1.hspp': No such file or directory
I searched the net for a solution, but no dice (apparently there are no
Haskell programs using -F -pgmF m4?), so I am writing here.
Any ideas on what is wrong?
