Word is not an instance of Bits
by Daan Leijen 29 Nov '04

29 Nov '04

Hi, I am trying to compile DData with nhc98, but unfortunately, the Word type is not an instance of the Bits class, so I find myself unable to do an unsigned shiftR operation on them... Is there a workaround? All the best, Daan. ps. I am not subscribed to this list, so please cc.

-t doesn't link

Hi, Even trivial programs don't link for me if I use the -t flag: $ echo 'main = putStrLn "Foo"' > q.hs $ nhc98 q.hs -o q -t /usr/lib/nhc98/ix86-Linux/PreludeAll.z.a(Monad_IO.z.o)(.data+0x228): undefined reference to `FN_NHC_46Internal_46_95apply1' /usr/lib/nhc98/ix86-Linux/PreludeAll.z.a(PutStrLn.z.o)(.data+0x3c): undefined reference to `FN_NHC_46Internal_46_95apply1' /usr/lib/nhc98/ix86-Linux/PreludeAll.z.a(Show_IOError.z.o)(.data+0x1e8): undefined reference to `FN_NHC_46Internal_46_95apply1' [...] /usr/lib/nhc98/ix86-Linux/PreludeAll.z.a(COrd.z.o)(.data+0x1c0): undefined reference to `FN_NHC_46Internal_46_95apply2' /usr/lib/nhc98/ix86-Linux/PreludeAll.z.a(ShowParen.z.o)(.data+0x50): undefined reference to `FN_NHC_46Internal_46_95apply1' collect2: ld returned 1 exit status $ This happens with both the 1.16-11 deb and CVS checked out earlier today. Both used ghc to compile nhc. Additionally, just an aesthetic issue, with dash as sh I also get: sh: Illegal option -- $ sh --version sh: Illegal option -- "if sh --version | grep -i gnu >/dev/null" in tprofprel should probably be "if sh --version 2> /dev/null | grep -i gnu >/dev/null" or somesuch. Thanks Ian
