[Pkg-haskell-maintainers] Bug#738428: GenBind.evalConstCExpr: Casts are not implemented yet

[John Millikin]

The version of libncursesw5-dev packaged in Debian Unstable includes this macro:

        #define NCURSES_BITS(mask,shift) (NCURSES_CAST(chtype,(mask))
<< ((shift) + NCURSES_ATTR_SHIFT))

which differs from the version on my build machine:

        #define NCURSES_BITS(mask,shift) ((mask) << ((shift) +
NCURSES_ATTR_SHIFT))

The new NCURSES_CAST() is breaking c2hs, which added support for
integer casts in version 0.16.6 (unstable has 0.16.5).

My recommendation is to upgrade the c2hs package version to at least
0.16.6. I've verified that "cabal install c2hs==0.16.6" lets ncurses
build on unstable.
