Thanks, Spencer Janssen already set me straight. It was indeed the lack of --package mtl. I'm pretty sure I didn't have that before, but my memory could be faulty. Thanks again, Deborah On Oct 9, 2006, at 5:57 PM, Ian Lynagh wrote:

That sounds like good news, thanks :-)
but an attempt to compile gives:
$ ghc example25.hs /usr/bin/ld: Undefined symbols: _mtlzm1zi0_ControlziMonadziState_evalStateT_closure _mtlzm1zi0_ControlziMonadziState_gets_closure _mtlzm1zi0_ControlziMonadziState_zdf1_closure _mtlzm1zi0_ControlziMonadziState_zdf7_closure _mtlzm1zi0_ControlziMonadziState_zdf9_closure _mtlzm1zi0_ControlziMonadziWriter_zdf5_closure _mtlzm1zi0_ControlziMonadziWriter_zdf7_closure collect2: ld returned 1 exit status
This didn't happen before.
Any ideas? Am I doing something wrong, or is there something wrong with the 20061008 snapshot?
Are you sure it used to work before, exactly like that? It looks like it is failing to link because you didn't use "-package mtl" or "--make".
Thanks Ian
