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?
Probably the missing file is where the preprocessor should store the output. Probably you need to write a wrapper script. See: https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/options-phas... Claude -- http://mathr.co.uk
