[wxhaskell-devel] processExecAsync and processExecAsyncTimed don't work in version 0.10.3

[Bernd H. <ber...@ic...>]

Hi all,

I am developing a test management GUI where processes are started and
their output (on stdout and stderr) are shown on corresponding console
windows. The process management worked quite OK with version 0.9.4 but
does no longer work in version 0.10.3 (using ghc 6.8.3 on Windows XP).

The attached small example application shows what happens: with
processExecAsync only garbage is shown on both the stdout and the stderr
console window, with processExecAsyncTimed the stdout console works
fine, but the stderr console shows nothing. Main.hs is the wxHaskell GUI
with two buttons, both calling the application compiled from
Testproc.hs, one using processExecAsync, one using the Timed variant.
The attached makefile builds everything.

If someone with understanding of the internals of wxHaskell could have a
look on this topic, I would be very grateful. Perhaps the (soon?) coming
new wxHaskell version 0.11 will do correctly?

Thanks,
Bernd
