Hi
Here's an addition to my "Mysterious function timer_settime" message:
This test program:
import HsShellScript
main =
call (exec "/bin/echo" ["bla bla"]
-|- exec "/bin/cat" [])
produces this output:
test: test: <stderr>: hPutStr: illegal operation (handle is
closed)<stderr>:
hPutStr: illegal operation (handle is closed)
test: timer_settimetest: : Invalid argument
timer_settime: Invalid argument
test: Exited (ExitFailure 1)
I'm almost sure that the two examples work fine in the last working version of
HsShellScript. They use GHC-6.11. (I can't verify this, since I have
GHC-7.0.4 version installed. The old GHC version isn't available as a Debian
package any longer.)
So there appears to be a downwards-incompatibilty in the GHC libraries. I'm
fiddling with the internals quite a bit, in order to get forks, pipes and
redirects etc. working.
Any hint would be appreciated.
Volker
