I have tried various things to no avail .... [EMAIL PROTECTED]:~/FTP/Haskell/unix-2.2.0.0/tests/timer$ runhaskell Setup.lhs build Preprocessing executables for Test-1.0... Building Test-1.0... [1 of 1] Compiling Main ( ./timer.hs, dist/build/timer/timer-tmp/Main.o )
./timer.hs:22:0: Unacceptable argument type in foreign declaration: Sigval When checking declaration: foreign import ccall safe "wrapper" mkNotify :: Notify -> IO (FunPtr Notify) => here is my Sigval def data Sigval = SivalInt Int | SivalPtr (Ptr Char) I did a find/grep for "Unacceptable argument" in the ghc compiler source and assuming no typo I didn't find. ?? Thanks.
