Hello,
I am getting what is to me a mysterious error in a test case that I am writing:
vigalchin@ubuntu:~/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:11:45: Not in scope: data constructor `FunPtr'
It seems like the compiler is complaining about the lack of FunPtr in it's symbol table but System.Posix is imported:
module Main where
import System.Posix
import Foreign
import Foreign.C
import Foreign.Ptr
main = do
let event = Sigevent{sigevFunction=(FunPtr (notifyFunc))} <<<<<< error here
timerId <- timerCreate Clock_Realtime Nothing
timerDelete timerId
return ()
notifyFunc :: Sigval -> IO ()
notifyFunc sigval = do
putStrLn "timer POP!!!!!!!"
return ()
I am probably looking right at the answer and not seeing it. ??
Thanks, Vasili
