Manlio,
so compiling to native machine code works ok but if using ghci byte-code interpreter doesn't ..... can you supply your program please?
Right. Can't you reproduce the problem?
The program is very simple (I was just testing your package, since I suggested the use of clock_gettime to Mauricio in a previous post):
import System.Posix.Realtime.RTTime import System.Posix.Realtime.RTDataTypes
main = do time <- clockGetTime Clock_Monotonic; print $ tvSec time print $ tvNsec time
runghc rttime.hs
I suspect that this is a problem with shared library loading in ghci, since the C code you use for your package, is also used by the base package (for the Posix subsystem).
By the way: I don't see reasons to add all that code, since it is not used.
^^^ which code?
However, when I tried to remove all the unused code, executing the program gave me a stack exception (maybe I have removed too many things...).
One personal note: I don't like `tvSec` and `tvNsec`, I think `seconds` and `nanoSeconds` is a better choice. ^^^ ok .. I agree and will change. I asked others for criticisms(constructive) when I put to hackage but didn't get any. This is good ...
Also, it would useful a function to compute elapsed time (maybe a general class in base package, and a specialized instance declaration in posix-realtime for the timespec?)
