With the new version of GHC (7.8.3) I am running into problems with cpp.
The header of one of the files of my uu-parsinglib library reads as follows:
{-# LANGUAGE NoMonomorphismRestriction,
RankNTypes,
FlexibleContexts,
CPP #-}
#define DEMO(p,i) demo "p" i p
#define DEMOG(p,i) demo "p" i (mkP (p))
module Text.ParserCombinators.UU.Demo.MergeAndPermute where
...
However when I try to compile this file I get error messages like:
Text/ParserCombinators/UU/Demo/Demo.hs:88:17:
Not in scope: data constructor ‘DEMOG’
So it seems that the cpp is no longer called at all.
Any hints? I am running:
MacBook-Doaitse:src doaitse$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.8.3
MacBook-Doaitse:src doaitse$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1

Any help is appreciated,
